SCM9B Series

Isolated, Intelligent Signal Conditioning Products


9B Intelligent Signal Conditioning High quality 9B modules provide cost-effective protection and conditioning for a wide range of distributed data acquisition and control applications including process monitoring and control, remote data logging, product testing, and motion and motor speed control.

Our extensive line includes fixed and programmable sensor-to-computer and computer-to-analog output interface modules, RS-232/RS-485 converters, RS-485 repeaters, and applications software. Accessories include a complete selection of backpanels, DIN rail mounting options, interface cables, mounting racks, power supplies, and other accessory items.

All 9B products are CE Compliant and manufactured per RoHS Directive 2002/95/EC.


These isolated modules provide complete sensor/RS-232C or /RS-485 interfaces with 15-bit measurement resolution. They accept a variety of voltage, current, thermocouple, RTD/thermistor, strain gage, timer/frequency, and multichannel digital inputs/outputs.


These are complete, isolated interfaces designed for remote installation and communication with host computers via standard RS-232C and RS-485 serial ports. They offer 12-bit resolution in a range of analog output voltages and currents.


These products convert RS-232C communication signal levels to the correct RS-485 signal requirements, and may also be configured as repeaters to extend communication bus lengths.
