*1: 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.
*2: For HART function specifications, refer to “HART Communication Functions” (GS 34P02Q53-01E). Yokogawa Analog Input Module NFAI143-S51/A4S10
*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: 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. Yokogawa Analog Input Module NFAI143-S51/A4S10
