712XBXC-120产品概述
712 Series Alternating Relays
712 series is designed for duplex pumping systems where it is desiderable to equalize pump run time. The solid state alternating circuit drives an international electromechanical relay. A continuous power source and control switch are required. The control switch is connected between the L1 terminal and the control terminal. Each time the control switch is opened the output contacts will change status. Indicator lights on the case show the internal relay status. Setting the top toggle switch to Load 1 or Load 2 will lock the relay in the position, preventing alternation.
