Current Conditioner
Dataforth product lines provide current conditioner solutions.
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.
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.
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
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
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.Loop Powered Two-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.PARAMETRIC SEARCH

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
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.
