Peltec Timers Monitor - Relay Output 256-480

The 256-480 is a three-phase voltage and phase sequence monitor designed to detect phase failure and incorrect sequence in 3×480VAC systems. It features a SPDT form C relay output rated at 8A/250VAC, with a fixed 500ms time delay (T1) and an adjustable delay (T2) of 0 to 10 seconds. The device operates with a minimum threshold adjustable from 70% to 95% of nominal voltage and a cutoff at 60%. A red LED indicates fault conditions, while a green LED confirms supply voltage presence. It offers DIN rail mounting, IP40 protection from the front panel, and complies with UL, CE, and RoHS standards. The relay has a mechanical life of 10 million operations and an electrical life of 100,000 operations. Operating temperature ranges from -20°C to +55°C, and dielectric strength is 4kV.
