Three-phase rotation direction changeover relaysThese relays are designed to start and reverse the rotation direction of three-phase motors. They have input/output line isolation with opto-couplers, with very high immunity to difficult environments, dV/dT, humidity, and combustible atmospheres. Status display. Applications, conveyor belts, packaging machines, crane girders, etc. Stock no. | **231-0854** | **231-0860** ---|---|--- **Control system performance:** |   |   Supply voltage: | 15 to 30 V dc | 15 to 30 V dc Supply current: | 18 mA max. | 18 mA max.
