Bulletin 700 Control Relays

The Allen-Bradley Bulletin 700 Control Relay family is a broad line of industrial control relays and timing relays covering electrically held, magnetically latched, and tube-base timing configurations across more than 1,000 catalog numbers. Decoding the catalog number is the fastest path to the right part: the prefix 700-R designates an electrically held relay while 700-RM identifies a magnetically latched (bistable) variant that retains its state through power loss — critical for safety-conscious applications. Front-deck configurations support 1–4 poles in any NO/NC combination using snap-in cartridges; a rear deck extends capacity to 8 poles. Replacement cartridges follow a consistent scheme: 700-CR5 (NO, green), 700-CR6 (NC, yellow), 700-CR7 (RM NO, blue), and 700-CR8 (RM NC, red). Coil voltage selections span AC voltages from 24 to 240 V and DC voltages from 12 to 250 V. Popular in-stock items include tube-base timing relays such as the 700-HT12CU24 (24 V AC/DC, DPDT, on-delay) and 700-HTF12600SU120 (120 V AC/DC, DPDT, on-delay), alongside universal mounting strips in 8- and 16-relay configurations. Consult the Bulletin 700 Control Relay Technical Data (700-TD003) for full electrical ratings and accessory compatibility.
