Yokogawa Analog I/O Module NFAI835-S50
Standard Specifications
Current Input Module and Current I/O Module (Isolated Channels)
The Current Input Module receives signals of 4 to 20 mA. The Current I/O Module receives and outputs signals of 4 to 20 mA. These two modules are isolated between the input/output signals and the system as well as between channels.

*1: A voltage drop by up to 0.8 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. Yokogawa Analog I/O Module NFAI835-S50
*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 GS 34P02Q53-01E HART Communication Functions.
*7: 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. Yokogawa Analog I/O Module NFAI835-S50
*8: 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.
