RIB® Dry Contact Input Relay RIB21CDC-N4 Enclosed Pilot NEMA 4/4X 120-277VAC 10A SPDT
The RIB21CDC-N4 is a versatile and reliable dry contact input relay designed for a wide range of applications. This self-powered relay can be activated by various dry contacts, such as thermostats, switches, and other relays, making it a convenient solution for various installations. Its isolated relay contacts can switch any power-load or low-voltage load, providing flexibility and ease of use. Suitable for use in various industries, including commercial and industrial settings, this relay is a valuable asset for control systems, automation, and monitoring applications, offering a cost-effective and efficient solution for controlling and switching electrical loads.
Top product features:
- Self-powered with dry contact input allows activation by a wide range of dry-contacts such as thermostats, switches, other relays, or solid-state switches.
- The relay contacts are isolated from the input power and the dry contact input, allowing them to be wired to switch any other power-load or low-voltage load.
- Can operate from any voltage from 120vac 277vac, providing flexibility in installation.
Top product applications:
- Industrial Control Systems
- Building Automation Systems
- Commercial Lighting Control Systems
Rib® dry contact input relay rib21cdc-n4 enclosed pilot nema4/4x 120-277vac 10a spdt the dry contact input rib series offers all the advantages of the standard rib line; plus it can be activated by a wide range of dry-contacts such as thermostats switches other relays solid-state switches etc. The dry contact input rib provides the low-voltage (class 2) power needed to activate the relay (self-powered) - just close the dry-contact input. The 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. The relay contacts are isolated from the input power and the dry contact input; thus they can be wired to switch any other power-load or low-voltage load (see specifications for contact ratings). One model can be used for many installations (model rib21cdc can operate from any voltage from 120vac - 277vac; see specifications for the input power of other models).
