An 8-pin Molex connector 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 43025-0800 with 8 female terminals 43030-0003. The Molex terminals
accommodate wire sizes from #20 - #24.
The relay outputs, when active, connect the POLARITY, SENSE, and ISOLATION
pins of the connector to the relay COMMON pin. The relays are rated at
120VAC/125VDC @ 1A; for DLM600 Series 600W, maximum ratings are 60V(PK),
30VA, and 1A. For DCS 1k, 1.2k, and 3k, the maximum ratings are 250V @ 8A. Any
change in output (voltage, current, etc.) initiated by the user from the RS-232, GPIB,
or Ethernet interface will generate a 10ms synchronization pulse at the rear panel
User Control Signal Connector of the master unit (Sync Signal).

Molex Pin Description
1
For RS-232/GPIB: FOLDBACK output signal, open collector,
active-low. Asserted when in foldback mode.
Reserved function for Ethernet interface.
3
FAULT output signal, open collector, active-low.
Asserted when a fault is recorded in the fault register.
6
POLARITY output signal, relay contacts. Asserted (contacts close
to COMMON) when a negative voltage is programmed.
(e.g., SOURce:VOLTage -5.0)
7
ISOLATION output signal, relay contacts. Asserted (contacts close
to COMMON) when the output relay is programmed OFF.
(e.g., OUTPut:ISOlation OFF)
8
SENSE output signal, relay contacts. Asserted (contacts close to
COMMON) when the sense relay is programmed OFF.
(e.g., OUTput:SENse OFF)
2
SHUTDOWN TTL input signal, active-high. Allows the user to
immediately shutdown the unit by a TTL input signal.
5 COMMON for all signals and relay contacts.
4
For RS-232/GPIB: SYNC output signal, open collector, active-low.
Pulsed for 10 ms when a change in the output occurs. Reserved
function for Ethernet interface.
