Potentiometer Input Module
Input Range: 0 to 100 Ohms
Output Range: 0 to +5 V
Mechanical Format: Modular plug-in-board
Each SCM5B36 potentiometer-input module provides a single channel of Potentiometer-input which is filtered, isolated, amplified, and converted to a high-level analog voltage output (Figure below). This voltage output is logic switch controlled, which allows these modules to share a common analog bus without the requirement of external multiplexers.
The SCM5B module family is designed with a completely isolated computer-side circuit which can be floated to ± 50V from Power Common, pin 16. This complete isolation means that no connection is required between I/O Common and Power Common for proper operation of the
output switch. If desired, the output switch can be turned on continuously by simply connecting pin 22, the Read-Enable pin, to I/O Common, pin 19.
