*1: For details, refer to example of connection methods and other settings in the input mode.
*2: 0.1 to 800 Hz for an open-collector contact input.
*3: The withstanding voltage for using MIL connector cable depends on the electrical specifications of its cable. If you are using KMS40 cable, withstanding voltage of between input and system is 500 V AC for 1 minute.
*4: Depends on the actual voltage applied by analog field power supply (24 V DC) via base module.
When this I/O module is used, 24 V DC needs to be supplied to an analog field power supply terminal of the power supply module.
