RIB Relays RIBD2421C Enclosed Pilot Control Time Delay Relay

RIB Relays RIBD2421C Enclosed Pilot Control Time Delay Relay is engineered for precise sequencing in automation and control panels. This AC/DC operated device offers versatile coil voltages (24/120-277 VAC at 50/60 Hz) and SPDT contacts for flexible control in a compact NEMA 1 enclosure.

With fast operate time and rugged Pilot Duty capabilities, it meets UL 916/864, CUL, UL (Canada and US), CE, and RoHS compliance, making it a reliable choice for demanding environments. The relay handles loads up to 277 VAC and 30 VDC (resistive), with a current rating of 7/10 A (resistive) and a power rating of 1/4–1 HP. An LED indicator provides quick status checks, and the unit ships with 16" of 600V-rated wire and a 0.5" threaded nipple for easy mounting.
