3.5.3 REMOTE CURRENT CONTROL USING D-C SIGNAL VOLTAGE
See Figure 3-17 for remote current control using a d-c signal voltage.
See Figure 3-18 for remote current control using a high impedance ±1V voltage. Preamplifier
“B” is used in the non-inverting configuration, so the output current will have the same polarity
as the input programming signal.

NOTES:
1. Set MODE Switch to CURRENT and CURRENT
CONTROL switch to OFF.
2. Local sensing shown. Remote sensing not
recommended for Current control.
3. For inductive loads in excess of 0.5mH, the BOP
output response may be optimized by placing a
capacitor across terminals (16) and (18) of the
Rear Programming Connector (
I
o COMP AMP).
