FAQ What is the life expectancy of the REL-MR-12DC/21 relay contact?The mechanical service life is approximately 2 x 10^7 cycles. The electrical service life is dependent on the switched load; please refer to the manufacturer’s load limit curve in the datasheet for specific application details. Is this module suitable for switching inductive loads?Yes, the AgSnO contact material is well-suited for switching resistive and inductive loads. For high-frequency switching of significant inductive loads, an external protective circuit (e.g., a freewheeling diode) across the load is recommended to suppress voltage spikes and prolong contact life. What is the wire size range for the screw terminals on the PLC-BSC-12DC/21 base?The screw terminals can accommodate a wire size range from 0.14 mm sq to 2.5 mm sq, which corresponds to AWG 26 to AWG 14.
