Reference Common Analog
Figure 14 Bridge Input Wiring Diagram
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.
