20-Amp SPDT High Power Relay Option
This controller is available with a 20-Amp relay option, allowing control of high-power loads up to an absolute maximum of 240VAC at 20 Amps. Ideal for high-power switching applications, this relay should never be used for low-power signals. The 20-Amp relay is of the SPDT variety, which provides Common (C), Normally Open (NO), and Normally Closed (NC) connections. Common is connected to NC when the relay is off. Common disconnects from NC and connects to NO when the relay is activated. This relay is Rated at 20-Amps between NO and C. Do not exceed 10-Amps between C and NC connections. This relay uses .250″ Quick Connect terminals (optional accessory) to connect to the top side of the relay. The relay is molded with COM, NC, and NO markings into the plastic. Review Datasheet
