*1: A voltage drop of up to 3 V may occur due to the internal protection circuit. Yokogawa Analog Input Module NFAI141-S51
*2: Depends on the actual voltage applied by analog field power supply (24 V DC) via base module.
*3: When this I/O module is used with 2-wire transmitter, 24 V DC needs to be supplied to an analog field power supply terminal of the power supply module. Yokogawa Analog Input Module NFAI141-S51
*4: For HART function specifications, refer to “HART Communication Functions” (GS 34P02Q53-01E).
*5: 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.
