*1: Avoid connecting a power supply that produces over 30 VDC. Avoid connecting an AC power supply. Connecting one of these power supplies may cause a malfunction.
*2: The FAIL signal contact output terminal, 24VDC terminal, and internal circuit.
*3: The FG terminal, 24VDC terminal, and internal circuit.
*4: If an inductive load, such as a relay, is connected, a surge suppressor is required on the load side. Install a surge suppressor or diode near the load to ensure that the voltage applied to the FAIL signal contact output terminal does not exceed the contact rating.
*5: When wiring to this module, be sure to use the terminal block provided. A 10-pole push-in terminal block (model: A2320JT) is available as spare parts.
