GENERAL
This GS covers the hardware specifications of analog input/output modules that can be installed in an FCN autonomous controller.
For connection with field equipment, refer to “Field Connection Specifications” (GS 34P02Q30-01E) and “STARDOM FCN/FCJ Installation Guide” (TI 34P02Q91-01E).
*1: A voltage drop of up to 3 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: 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.
*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
