Description

The SCMD digital output modules are used for switching AC and DC loads such as relays, solenoids, motor starters, or indicator lamps. All models provide up to 4000Vrms of optical isolation between the field device and the control logic. The AC output modules incorporate zero voltage switching and an RC snubber circuit which allows switching heavy inductive loads. Functionality is denoted by case color—AC modules are black, and DC modules are red.

Six backpanels are available for mounting SCMD-M digital output modules.

FAQ

Frequently Asked Questions


Can Dataforth provide calibration reports for modules I purchased?
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

In DC Digital Output Modules, does Dataforth have any with Iout > 3A?
Yes, Dataforth has the SCMD-MODC5ML which can switch up to 5A DC from an off-state voltage up to 50VDC.

The basic data sheet can be found in the Dataforth Full-Line Catalog under SCMD–MOAC/MODC Miniature Digital Output Modules and at www.dataforth.com at the upper left, under Explore our product offerings:, click on Signal Conditioning. Then click on Isolated Digital I/O Modules. In the top center of the next page, click on the Adobe Acrobat symbol to the right of SCMD–MOAC/MODC. At the right edge of the page in a text box labeled Datasheet, click on SCMD Specifications for detailed specifications of all Digital I/O Modules.

How do I convert an RMS voltage to its corresponding peak voltage?
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

If the input range of my signal conditioner is -1V to +1V and the output range is 0 to 10V, does this mean that it ignores polarity?
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.

How does the load resistance of a module affect the noise at the output?
Noise at the output of a module is independent of load resistance.

What is the minimum current required to switch the output for the SCMD-MODC?
The current required to switch the output for the SCMD-MODC is 27mA. You can find this information in the datasheet on our website: https://www.dataforth.com/catalog/pdf/SCMD-MXXX-specsheets.pdf

Can the SCMD-MODC be used directly to drive loads such as solenoids? Or are these modules used to effectively step-up a low-level digital output, which can then get used to control a relay?
Yes, the SCMD-MODC modules can be used to directly drive loads such as solenoids. The maximum on state current for some SCMD-MODC models can be up to 5A.
