Failure to do so may cause unexpected behavior of the loads.
2. Configure the external circuit so that the external 24Vdc power required for the transistor output circuits and power to the loads are switched on/off simultaneously. Also, turn off power to the loads before turning off power to the
3. Install fuses appropriate to the load current in the external circuits for the outputs. Failure to do so can cause fire in case of load

(2) Switching life of output relays
Expected relay life is more than 100,000 electrical cycles at rated maximum voltage and current, and more than 20 million mechanical cycles. The expected contact life (electrical cycles) is shown on the table below.
