RELAY X COMMON One of Eight Typical N/C 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. 654 840 USE 100 00 September 2002
