System compatibility

T9801 belongs to ICS TRIPLEX AADvance safety instrumented system,DIN rail mounted outside the main rack. It serves as field termination and signal conditioning unit for AADvance digital input module,collecting discrete status signals from field limit switches,valve position feedback and pressure switches. Widely deployed in oil & gas,petrochemical and power plants for ESD and fire & gas safety applications.

Function

T9801 is high integrity commoned digital input termination unit for AADvance SIS. It provides terminal connection,surge protection and signal conditioning for 16-channel field discrete signals. It transmits conditioned field signals to AADvance DI module and supports simplex,dual and TMR redundant configurations.

Installation

Mount T9801 on standard DIN rail inside control cabinet. Wire field switch sensors to T9801 terminal blocks,connect signal cable from FTA to AADvance DI module. Verify signal quality and wiring fault via AADvance Workbench engineering software.

Interface

‑Field terminal blocks for 16-channel 24VDC digital input wiring

‑Signal output terminals to AADvance DI module
