Pressure clamp terminal

*1: Type B does not carry out temperature compensation and can not measure under 44°C.
*2: Each wiring resistance should be equal. Yokogawa RTD Input Module NFAR181-S04
*5: Use a MIL connector cable for only mV input.
*6: The NFAT141 thermocouple input module imposes limitations in installation. See “Restrictions and Precautions on Installation”.
*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.
