System compatibility

T9831 belongs to ICS TRIPLEX AADvance safety instrumented system,DIN rail mounted outside main rack. It serves as field termination and signal conditioning unit for AADvance analog input modules,accepting 4-20mA signals from pressure,temperature and level transmitters. Widely deployed in oil & gas,petrochemical and power plants for ESD and fire & gas safety applications.

Function

T9831 is high integrity simplex commoned analog input termination unit of AADvance SIS. It provides terminal connection,precision loop resistance and fuse protection for 16-channel analog field signals. It converts field transmitter current signals to matched input for AADvance AI module,designed for simplex safety configuration.

Installation

Mount T9831 on standard DIN rail inside control cabinet. Wire field transmitters to T9831 terminal blocks,connect signal cable from FTA to AADvance analog input module. Verify channel reading and loop health via AADvance Workbench engineering software.

Interface

‑Field screw terminal blocks for 16-channel 4-20mA analog wiring

‑Replaceable 50mA fuses per channel group

‑Signal output terminals to AADvance AI module

‑Onboard precision 135Ω loop load resistor and surge suppression circuit

Circuit feature

Rugged compact PCB design,built-in surge and overvoltage protection. Commoned loop architecture for simplex system,fully compliant with SIL3 functional safety hardware specifications.

Feature

T9831 is spare simplex commoned analog input FTA for ICS TRIPLEX AADvance SIS. Common faults include blown fuses,terminal loosening and loop wiring open/short circuit. Confirm AI module model before replacement.

Diagnostic

When fuse failure,loop open/short circuit or signal abnormality is detected,corresponding fault alarm will be displayed on matched AI module and uploaded to safety workstation.

Built‑in function

Field 4-20mA analog signal termination,onboard loop resistance,fuse overcurrent protection and conditioned signal transmission for AADvance analog input module,used as SIS simplex AI FTA spare replacement.

Product Brief

T9831 is ICS TRIPLEX SIL3 AADvance 16-channel simplex commoned analog input FTA,DIN rail mounted,matched with AADvance AI modules for field transmitter signal termination in simplex safety configuration. Verify system firmware compatibility before ordering. ESD anti-static protection must be followed during handling installation.
