NFAI143-H50

*1: A voltage drop by up to 3 V may occur due to the internal protection circuit.
*2: Depends on the actual voltage applied by analog field power supply (24 V DC) via base module.
*3: HOLD: To hold output in which fallback is detected.
SETV: To output a specified value when fallback is detected.
*4: Select fallback [Yes/No] for each module.
If [Yes] is selected for fallback, set [HOLD/SETV] for each channel.
Fallback detection time: 4 seconds
*5: 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.
*6: For HART function specifications, refer to “HART Communication Functions” (GS 34P02Q53-01E).
*7: A Zener barrier is not allowed to be connected with this module. Use an isolation barrier when the module is used in
intrinsically safe application.

*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.
