4.6 Remote Inhibit [Option]

A Remote Inhibit BNC input is located on the rear panel of the 2003RP if the -OP1 option

was specified at the time of purchase. This input may be used to disable the AC source

output using an external control signal.

Default mode of operation

If the Remote Inhibit (RI) input is left unconnected, the output of the AC source can be turned

on using the OUTPUT button on the front panel or the appropriate bus command. To disable

the output relay, a logic low level or a contact closure needs to be present across the

terminals of the RI BNC connector.

Typical use of the RI input is in rack systems where the RI input is wired to a switch that

detects removal of the rear panel. This input may also be used to simultaneously shut down

multiple AC power sources.

Note that the RI input has an internal pull-up resistor to TTL logic high. When the RI input

cable is disconnected, the output will recover and the output relay will be closed

automatically.
