Solid state relay BI-25

Solid-state relays of the BI series (hereinafter referred to as the device) are a single-phase thyristor (triac) AC switch consisting of a switching device and a thyristor (triac) control circuit.
Solid state relays of this series provide switching of power circuits for loads of resistive or inductive type. Ideal for switching control circuits in PID and ON/OFF control systems.
Wiring recommendations: when driving an inductive load, it is necessary to install a varistor in parallel with the load circuit.
