*1: A voltage drop by up to 3 V may occur due to the internal protection circuit. Yokogawa Analog I/O Module NFAB841-S51
*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. Yokogawa Analog I/O Module NFAB841-S51
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.
