Product Details
The RIB® dry contact input relay RIB02SBDC-NC is an enclosed device designed for use with 208-277VAC, 20A applications, featuring a Single Pole Single Throw Normally Closed (SPST-N/C) override. This relay offers the advantages of the standard RIB line while being activatable by a versatile range of dry contacts, including thermostats, switches, other relays, and solid-state switches. It requires low-voltage Class 2 power to activate the relay, being self-powered simply by closing the dry contact input. Power to energize the relay can be supplied through a separate pair of wires or from a local power source. Importantly, the relay contacts are isolated from both the input power and dry contact input, enabling them to switch various power loads or low-voltage loads; detailed specifications for contact ratings are provided. Additionally, one model supports multiple installations; for instance, model RIB21CDC can operate from any voltage ranging from 120VAC to 277VAC, with specific input power requirements outlined in the specifications. The product includes warranty information and complies with relevant industry standards.
