Model 755A
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-in current-output
board.
Dual Alarm Amplifier Circuit. This circuit drives
the optional 638254 Alarm Relay Assembly.
