Power-Control Relays

New line of solid-state power-control relays provide controlled line voltage output proportional to the command signal received.

Operating from a 24-Vdc isolated power supply, the devices use an input control from 4 to 20 mA or 0 to 10 Vdc. Features of the relays include an integral heat sink for controlled cooling, DIN-rail mounting system for easy mounting and removal, and UL, CSA, VDC, and CE approvals. Standard models are for applications requiring 10 to 40 A at a maximum operating temperature of 40°C ambient. The relays are for use in the plastics, food-processing, semiconductor, and laboratory industries.
