3.4.2 Bridge Sensor Input Option

Caution: Improper initial setup of the Bridge Input Option could damage the attached bridge sensor.
!
Complete the Bridge Sensor Initial Setup in Chapter 3.4.2.1 prior to initial powering of the sensor.
An optional 16-channel, 12 bit Bridge Sensor Input board allows popular gas detectors to be connected
directly to the ViewSmart 1600+ without additional signal conditioning or transmitters. Up to eight dual
channel 10-0192 modules may be installed in each 16-channel 10-0347. Each 10-0192 channel is equipped
with a bridge amplifier and balance potentiometer and an adjustable switching regulator for setting the
correct sensor excitation voltage. A three position coarse gain jumper allows setting the gain of the bridge
amplifier. Fault supervision circuitry forces the ViewSmart 1600+ into a FAULT condition upon sensor
failure or removal.
