Second Stage Amplifier

This amplifier is an inverting configuration that provides a signal attenuation of 2X, thus reducing the 10-volt fullscale input signal to obtain a 5-volt fullscale output. This output is routed to:

Recorder Output Resistor Network. It provides a jumper-selectable output of 0 to 10 mV, 0 to

100 mV, 0 to 1V, or 0 to 5VDC for a potentiometric recorder.

Current Output Receptacle J1. This connector accepts the optional plug-incurrent-output board.

Dual Alarm Amplifier Circuit. This circuit drives the optional 638254 Alarm Relay Assembly.
