5B Isolated Analog Current Signal Conditioning Products

5B Current Conditioner Modules SCM5B32 Input Current Conditioner: Each SCM5B32 input current signal conditioner provides a single channel of analog current input which is filtered, isolated, amplified, and converted to a high-level analog voltage output. This voltage output is logic switch controlled, which allows these modules to share a common analog bus without the requirement of external multiplexers.

SCM5B39 Output Current Conditioner: Each SCM5B39 output current signal conditioner provides a single channel of analog output. The track-and-hold circuit in the input stage can be operated in a hold mode where one DAC can supply many output modules, or a track mode where one DAC is dedicated to each module. In addition to the track-and-hold circuit, each module provides signal buffering, isolation, filtering, and conversion to a high-level current output.
7B Isolated Process Control Current Signal Conditioning Products
7B Current Conditioner Modules SCM7B32 Isolated Current Conditioner Modules: The SCM7B32 input current signal conditioning modules accept input signals in the 4-20mA or 0- 20mA ranges from the field and provide a high-level output to the process control system. Current to voltage conversion occurs internal to the module, which is factory calibrated to ensure the highest accuracy.

SCM7B39 Isolated Process Current Output Modules: SCM7B39 process current modules accept high-level signals from the process control system and provide either 0 to 20mA or 4 to 20mA current to the field.
World's Smallest Isolated Analog Current Signal Conditioner
Miniature Current Conditioner Products 8B32 Input Current Conditioner Module: 8B modules are an optimal solution for monitoring real-world process signals and providing high-level signals to a data acquisition system. Each 8B32 module isolates, filters, and amplifies a process current input signal and provides an analog voltage output.

8B39 Output Current Conditioner Module: 8B modules are an optimal solution for monitoring real-world process signals and providing high-level signals to a data acquisition system. Each 8B39 module accepts an input signal from a non-isolated source, then isolates, filters, and converts the signal to an analog process current output.

High Performance DIN Isolated Analog Current Signal Conditioners
DSCA DIN Rail Mount Isolators DSCA32 Analog Input Current Signal Conditioners: Each DSCA32 current input module provides a single channel of analog input which is filtered, isolated, amplified, and converted to a high-level voltage output. Signal filtering is accomplished with a five-pole filter which which is optimized for step response. An anti-aliasing pole is located on the field side of the isolation barrier, and the other four poles are on the system side. After the initial field-side filtering, the input signal is chopped by a proprietary chopper circuit. Isolation is provided by transformer coupling, again using a proprietary technique to suppress transmission of common mode spikes or surges.

DSCA39 Output Current Signal Conditioners: Each DSCA39 current output module provides a single channel of analog output. The input signal is buffered, isolated, filtered and converted to a unipolar or bipolar current output. Signal filtering is accomplished with a five-pole filter which provides 100dB per decade of attenuation above 1kHz. An anti-aliasing pole is located on the system side of the isolation barrier, and the other four poles are on the field side. After the initial system-side filtering, the input signal is chopped by a proprietary chopper circuit. Isolation is provided by transformer coupling, again using a proprietary technique to suppress transmission of common mode spikes or surges.
User Programmable Temperature Transmitters
DSCP Current Conditioner Module DSCP81 Configurable Voltage/Current Input Signal Conditioner, DIN Mount: Each isolated DSCP81 signal conditioner is designed for measuring voltages up to ±1000VDC and currents up to ±100mA. The input type, measurement range, and other features are software configurable. A PC with RS-232C serial port, the DSCX-787 and DSCX-587 interface cables, and the DSCX-557 configuration software are required to program the DSCP81.

DSCP61 Pt100-to-DC Current/Voltage Converter: Each DSCP61 RTD Pt100 Converter provides a single channel of RTD input which is amplified, linearized and converted to a high-level current or voltage output. Inputs may be connected by 2, 3, or 4 wires and measurement range may be configured by dip-switch to cover a range of –150°C to +650°C. Power can be applied directly to the converter’s terminals or through a DIN rail mounted bus connector accessory, eliminating the need to wire power to each individual converter.
Loop Powered Two-Wire Transmitters
Isolated DIN Rail Mount 2-Wire Transmitters DSCT Analog Current Input Transmitters: Each DSCT32 current input transmitter provides a single channel of analog input which is filtered, isolated, amplified, and converted to a process current output. Signal filtering is accomplished with a five-pole filter, which provides 80dB per decade of normal-mode rejection above 100Hz. An anti-aliasing pole is located on the field side of the isolation barrier, and the other four are on the process loop side. After the initial field-side filtering, the input signal is chopped by a proprietary chopper circuit. Isolation is provided by transformer coupling, again using a proprietary technique to suppress transmission of common mode spikes or surges.
