System compatibility

T9851 belongs to ICS TRIPLEX AADvance safety instrumented system,DIN rail mounted outside main rack. It serves as field termination and signal conditioning unit for T9451 DO module,transmitting 24VDC safety trip output signals to field solenoid valves and safety relays. Widely deployed in oil & gas,petrochemical and power plants for ESD and fire & gas safety applications.

Function

T9851 serves as high integrity simplex commoned digital output termination unit of AADvance SIS. It provides screw terminal connection,surge protection and signal conditioning for 8-channel safety output signals. It is designed for simplex safety configuration and passes safety trip commands from DO module to field actuators.

Installation

Mount T9851 on standard DIN rail inside control cabinet. Wire field solenoid valves and safety relays to T9851 terminal blocks,connect signal cable from FTA to T9451 digital output module. Verify output status and wiring fault via AADvance Workbench engineering software.
