SCM5B43-04D

DC channel to channel isolation for all SCMPB backpanels is 2121 VDC.

SCM5B, SCM7B, 8B SensorLex, and DSCA modules are well suited for use in high vibration environments. These modules and their associated accessories have undergone testing for random vibration, shock, and swept sine wave vibration. Details of each of these testing methods are provided below: Random Vibration (Operating): ○ MIL-STD 202G, Method 214A, Condition 1 - Frequency Range: 50-2000Hz, flat spectrum - Vibration Intensity: 7.56 Grms - Duration: 10min/axis (X, Y, Z) Shock (Operating): ○ MIL-STD-810F, Method 516.5 - Pulse Shape: Sawtooth - Test Level: 30G - Duration 11ms - Orientation: +/-X, +/-Y, +/-Z Swept Sine Vibration (Operating) ○ MIL-STD-810G, Method 514.6, modified - Frequency Range: 10-2000Hz - Vibration Intensity: 5Gp-p - Sweep Rate: 1 octave/min - Orientation: X, Y, Z Declaration of conformity for the above-listed tests can be provided upon customer request. Please contact customer service if a copy of the declaration is needed.

Two dimensional CAD models can be generated upon customer request. Please contact Customer Service for assistance.

A 3kHz bandwidth on an input module means it can accept voltages from DC to 3000Hz. Any frequency higher than that and the signal will start to be attenuated by the filter at the input.

Normally, a response time figure refers to how quickly a module's output can "respond" to a change in the input signal. "Response time, 90% span" refers to how fast a module can adjust its output when a step signal is applied at the input, where the magnitude of this step input is 90% of the input span of the module.

Yes, any signal conditioning module series and MAQ20 I/O modules can be hot swapped. A minimal amount of signal settling time may result, but there will be no damage to the device.

Yes, the DIN rail mounting hardware for the SCMPB04 can be easily detached and reattached from the board.

Please see the SCM5B Module Dimensions and Pinouts link from the SCM5B section of our website: https://www.dataforth.com/catalog/pdf/scm5bdim.pdf You can also find the module dimensions and pinouts in our product catalog.

The DIN rail mounting of the SCMPB04 can mount to DIN rail types EN 50022-35x7.5, EN 50022-35x15, EN 50035-G32. These can be purchased as part numbers SCMXRAIL1-XX, SCMXRAIL2-XX, pr SCMXRAIL3-XX where XX is specified as the length of the rail in meters.

Information on MTBF for SCM5B, SCM7B, 8B and DSCA is available on our website. Please see application note AN802 for more details. Application notes can be found under the "Literature" tab on the top navigation bar.

We do not recommend soldering the SCM5B pins to a board as it could potentially damage the module. Soldering the pins would also void the warranty. Many sockets are available which accept the mounting pins. TE Connectivity / AMP part number 50865-5 is an example of these sockets and any equivalent part will work as well.

Vout is used with input modules, which are all the SCM5B models except for the SCM5B39 and SCM5B49. Vin is used for output modules, SCM5B39 and SCM5B49. The reason for doing this is because input modules acquire a signal from the field side, and then output a corresponding signal to the system side. On the contrary, output modules acquire a signal from the system side, and then output a corresponding signal to the field side. Since SCM5B backplanes are designed for all channels to accommodate either an input or an output module, the terminal/pin that you would normally get your output signal from if you were using an input module is the same terminal/pin that you would be feeding your input signal to if you were using an output module.

Yes, calibration of Dataforth modules is traceable to NIST standards.

No, converting any of the 16 channel SCM5B backplanes to something DIN rail mountable is a much more involved process than the SCMPB03/04. If you would like a 16 channel SCM5B backplane that can mount on a DIN rail you must purchase an SCMPB01-2, SCMPB01-3, SCMPB02-2 or SCMPB02-3.

No, all SCM5B modules have the same power requirements (5VDC) regardless of their I/O specifications. The power supply current draw of different products in the SCM5B line may vary.

Yes. Backplanes with no CJC will still come with the CJC enable installed on the backplane.

J1-J4 on the SCM5B backpanels are jumper cables, so they should have 0 ohm resistance.

It is not recommended to ground the sensor wire shield to the 10-32 ground post on the SCMPB01 because that is the system side ground, while the sensor wire is on the field side. The sensor wire shield should be grounded to the field side ground, which varies based on the signal conditioner you are using. Please see the "Shield Grounding" application note for more information.

The factory configuration for jumpers J1 through J4 is the optimal configuration for most applications. If for some reason this jumper configuration will not work/is not working in your application, see our application note AN502 "Ground Connections and Host System Interfaces" for other valid jumper configurations and what situations you would use them.

No, the SCMPB03 comes with the CJC built into the backpanel.

The failure rate calculations for our SCM5B modules can be found in our application note AN503: https://www.dataforth.com/catalog/pdf/an503.pdf There are no dominant failure modes.

Yes, any of our SCM5B modules are able to be mounted and operated on Omega's OM5-BP-SKT-C board.

None of our standard SCM5B modules have a 50kHz bandwidth. However, it is possible to order a custom SCM5B module with 50kHz bandwidth. Keep in mind that new customs require a 10 pc minimum order and are subject to extra design fees.

Although we do not carry signal conditioners that can interface with AC LVDTs, we do have the SCM5B43, 8B43 and DSCA43 which can interface with DC LVDTs.

Yes, the SCM5B modules are isolated up to 1500 Vrms, which means that if the common mode voltage between the field side and system side is limited to 1500Vrms, the device will be protected. However, the input protection for SCM5B modules (i.e., the voltage across the +IN and -IN input terminals) is 240Vrms max.

Noise at the output of a module is independent of load resistance.

To convert an RMS voltage to its corresponding peak voltage, you simply take the RMS voltage value and multiply it by the square root of 2, or roughly 1.414. For example, 1500Vrms corresponds to a peak voltage of 1500 * 1.414 = 2121 Vp

A signal conditioner with these I/O ranges does not mean that the module ignores the polarity of your voltage input. The output of voltage input modules are scaled linearly, meaning an input of -1V would correspond to an output of 0V, an input of 0V would correspond to an output of 5V, an input of +1V would correspond to an output of 10V, and so on.

The recommended power supply for the Dataforth SCM5B and 8B modules are the linear power supplies in our SCMXPRT/SCMXPRE series. The SCMXPRT/SCMXPRE power supplies output 5V and have options for 1A output current (SCMXPRT-001) or 3A output current (SCMXPRT-003). The SCMXPRE series is identical to its SCMXPRT counterpart, but is configured for European voltage standards. The SCMXPRT-001/SCMXPRE-001 both have the option for DIN rail mounting as well (SCMXPRT-001D/SCMXPRE-001D). Other power supplies that meet that power requirements of the SCM5B and 8B modules can be used as well, but it is strongly recommended to use a linear power supply rather than a switch-mode power supply. Switching power supplies can add noise artifacts to the output of your modules.

The SCMXPRT-001 has an option for DIN rail mounting (part number: SCMXPRT-001D) but the SCMXPRT-003 does not. Instead, it can be mounted on the SCMXRK-002 which is a 19 inch metal rack for mounting the SCMXPRT-003 as well as various Dataforth backpanels and the SCMXIF interface board.

Yes, in general, Dataforth signal conditioning modules are a direct replacement for all Analog Devices signal conditioning modules. e.g. "SCM5B35-xx: Linearized 4-Wire RTD Input Modules" will replace Analog Devices "5B35: Isolated 4 Wire RTD Input Signal Conditioning Module". Please note that Dataforth signal conditioning modules are RoHS II compliant.

Yes we can provide calibration reports for the modules that you purchased. You can either a) visit https://www.dataforth.com/TestDataReport.aspx to search for Test Report Datasheets by Serial Number or b) you can send us a list of model numbers and their serial numbers to support@dataforth.com
