描述

The LJR224AD is an electronic alternating relay designed to replace mechanical devices in control applications requiring duplexing or alternating action of control circuits for pumps, compressors, and similar equipment. It features SPDT or DPDT control relay configurations with 10 A resistive rated output contacts, AgCdO contact material, and operates on 24 VAC/DC, 110 VAC, or 220 VAC input (±15%, 50/60 Hz) with maximum power consumption ranging from 1.5 VA to 11 VA depending on input voltage. The relay provides a minimum pulse response of 30 ms, maximum switching voltage of 250 VAC/250 VDC, and delivers a maximum power rating of 2200 VA with mechanical life of 3×106 operations and electrical life of 2×106 operations at 2200 VA resistive load. The dust-resistant enclosure includes two red LEDs for status indication, operates over -10°C to +60°C, and is ideal for industrial control systems requiring reliable alternating or duplex switching functionality.
