Securitron RB-4 Relay Board

Securitron, RB-4 Relay Board

Product Overview

The RB4 board mounts four double pole, double throw relays with connection points to the coils and contacts being implemented on screw terminals. The boards are furnished on Snap Trak mounting permitting their installation in a variety of situations. The relays provide 2amp contacts on each pole. The 12 volt version of the board uses relays that draw 13 mA each and the 24 volt version uses relays that draw 8 mA each. The relays operate on DC only but will accept +50%, -25% of nominal voltage. Pulsating DC (transformer + bridge rectifier) will operate the relays. According to the status of jumper wires, the relays may be operated with one side of their coils in common or they may be fully isolated from each other.
