SCM9B Series Intelligent Signal Conditioning Modules

Dataforth SCM9B modules provide cost-effective protection and conditioning for a wide range of valuable industrial control signals and systems. The extensive SCM9B line includes fixed and programmable sensor-to-computer input and computer-to-analog output interface modules, RS-232/RS-485 converters, RS-485 repeaters, and associated backplanes, accessories, and applications software. All products are European EMC Directive Compliant.

SCM9B-1000/2000/5000/D100 sensor-to-computer 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 gauge, timer/frequency, and multichannel digital inputs/outputs. 2000 series modules include additional programmable features such as ASCII output scaling to desired engineering units and linearization using straight-line segment approximation. 5000 series modules provide four analog input channels. The D100 series modules are DIN-rail mountable.

SCM9B-3000/4000 computer-to-analog output modules are complete, isolated interfaces designed for remote installation and communications 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. 4000 series modules have fully programmable output slopes, true analog readback, and data scaling.

SCM9B-A1000/2000/D192 converters and repeaters convert RS-232C communications signal levels to the correct RS-485 signal requirements and may also be configured as repeaters to extend communications bus lengths. They are optically isolated, require no external control signals, and are completely transparent to host software.
