Wiring Diagram
The following figure shows the DRC83000 wiring diagram.
NOTE:
1. When switching DC voltages, it is recommended that the source be connected to
the common pin and the load be connected to the N.O. or N.C. contact.
2. For 125 Vdc inductive loads, external clamping is recommended to extend relay
contact life (1N 4004 or equivalent).
3. N / C = Not Connected. N.O. = Normally Open. N.C. - Normally Closed.
