Auxiliary Relays
Section Overview
Electrical Specifications:
Relay circuit rated to
switch:
2 A at 30 VAC or 30 VDC, resistive load.
Contacts:
Relay contacts are Form C dry contacts. Transorbs provide
suppression to Earth. Do not switch voltages greater than rating, or
damage may result.
Power
When power through auxiliary contacts is provided by the power supply, wiring is power-
limited.
When power through auxiliary contacts is not provided by the power supply, use in-line fuse
holder 208-165 with 208-183, 1A fuse with attached cap (supplied separately). If the power
source is not power-limited to the requirements of UL864, wiring is to be segregated to the
non-power-limited spaces of the cabinet.
Note:
The Aux Relays terminals on
the IDNAC power supply are
controlled by two on-board
programmable relays. The
relay circuits are not
supervised
