Functional Devices RIB21CDC-N4 : Dry Contact Relay, 10 Amp SPDT, Class 2 Dry Contact Input, 120-277 Vac Power Input, NEMA 4X Clear Housing

Functional Devices RIB21CDC-N4 : Dry Contact Relay, 10 Amp SPDT, Class 2 Dry Contact Input, 120-277 Vac Power Input, NEMA 4X Clear Housing

Product Features

• Prepackaged for quick and easy installation
• Provides low-voltage (Class2) power needed to activate the relay (self-powered) by closing the dry contact input
• Activated by a wide range of dry contacts such as thermostats, switches, other relays, solid-state switches, etc.
• Power to energize the relay can be brought to the relay on a separate pair of wires along with the control output of the controller, or can be a local power source near the relay
• Relay contacts are isolated from the input power and the dry contact input, so they can be wired to switch any other power-load or low-voltage load (see specifications for contact ratings)
