ER-2 External Relay with DPDT Relay – #800-5624 – SPECIAL ORDER
The CIRCUITRON ER-2 circuits consisting of a 2 amp relay, double pole double throw, and all the necessary driver circuitry to enable it to be directly connected to the output of any CIRCUITRON Detection Units. The relay contacts can be used to control AC or DC circuits and are ideal for use with CIRCUITRON Block Occupancy Detectors to provide automatic train control. The ER-2 has 12 volt relays and requires a supply voltage of 11 to 14 volts DC. The ER-2 presents a negligible load on the Detection Unit to which it is connected as the control current is only around 2 milliamps.
