Weidmuller Solid State Relays 2986890000

The PSSRN K 24VDC 1Z K 240VAC 20A is a solid-state relay designed for switching AC loads up to 20 A at voltages between 24 and 230 V AC. It features a compact width of 17.8 mm, integrates a heat sink, and mounts directly on DIN rail TS35. The control voltage ranges from 3 to 32 V DC with a nominal current of 7.5 to 11 mA, and the output is a zero-crossing thyristor with integrated varistor protection. It supports wire connections up to 2.5 mm² on the control side and up to 6 mm² on the load side, secure with M3 and M4 screws respectively. The device includes a green status LED, operates in ambient temperatures from -40 °C to 80 °C, and complies with RoHS and cULus E537615 standards. Its MTTF is 28 years.
