The 12Vdc powered RLB8-DP features a strip of eight (8) individual dual buffered, Double Pole / Double Throw (DPDT) Relays which share a common power rail. (Relays may be separated from the strip for individual or group use.) Each relay features a transistor buffered input which may be triggered by any positive DC voltage over 5Vdc or by 0Vdc. (Inputs are provided for + or – trigger). Each relay segment is provided with a common pole link for each relay pole (DPDT=2 Poles) By setting this link, either +ve or -ve may be jumpered to the common of either relay pole.
