EXTERNAL USER CONTROL SIGNAL

CONNECTOR

A10-pin Molex connector (Figure 5-7) located at the rear panel provides
external auxiliary control signals to increase the user’s operating control of
the supply. The mating receptacle is Molex 43025-1000 with 10 female
terminals. The Molex terminals accommodate wire sizes from #20 - #24.

The relay outputs, when active, connect the POLARITY, ISOLATION and
SENSE pins (Pins 6, 7 and 8) of the connector to the relay COMMON pin
(Pin 5). The relays are rated at 120VAC/125VDC @ 1A. Any change in
output (voltage, current, etc.) initiated by the user from the RS232, GPIB, or
Ethernet interface, will generate a 10ms synchronization pulse at the rear
panel User Control Signal Connector of the unit (TRIGGER OUT).
