HiComponet AC Solid State Relay Module input can be 220VAC, 380VAC, 3-32VDC, 1A, 3A, 5A current, load operating voltage is 220VAC, 380VA, 50VAC, etc. Its input to output are in 1KV optical isolation, silicon controlled output or FET (Filed effect tube) output. Its external package has two types: 35mm DIN Rail-mount or PCB-mount. Small size, fast response, 1mA small leakage current, it is ideal to use it in machine controlling system or communication system.
