GENERAL
This GS covers the hardware specifications of the Analog I/O Modules (for FIO) that can be installed in the Node Unit for ESB Bus (Local Node) (ANB10S, ANB10D), the Node Unit for ER Bus (Remote Node) (ANR10S, ANR10D) and Compact Field Control Unit (for FIO) (AFF50S, AFF50D, AFV10S, AFV10D).
STANDARD SPECIFICATIONS
Current/Voltage Input Modules (Non-Isolated)
These modules mainly receive 4 to 20 mA DC or 1 to 5 V DC standardized signal from 2-wire/4-wire transmitters. They can be used in dual redundant configuration.
TC Input/RTD Input Module (Isolated Channels)
These modules receive signals from mV, thermocouple (TC), RTD, and potentiometer (POT). These are isolated between the field and the system as well as between each channel.
They can be used in dual redundant configuration.
These two modules can be used in dual redundant configuration.
