TELE Controls Inc. Monitor - Relay Output E3YM230VS20

E3YM230VS20 is a multifunction voltage monitoring relay for 3- and 1-phase AC mains, with adjustable undervoltage, overvoltage, and phase sequence monitoring. It features two potential-free changeover contacts with a switching capacity of 1250VA (5A at 250V), housed in a 35 mm wide DIN-rail mountable housing with IP40 protection. The device operates from 132 to 230V AC, accepts a neutral connection, and monitors phase failure and sequence via a selectable rotary switch. Tripping delays are adjustable from 0 to 30 seconds, with a reset time of 500 ms and a rated surge voltage of 4 kV. Terminal connections support 0.5 to 4 mm² conductors, and the relay has a mechanical life of 20 million operations and an electrical life of 200,000 operations at 1000VA resistive load. Ambient temperature range is -25°C to +55°C.
