Products Description
ICS TRIPLEX T9852 (9852) 8-Channel Dual Digital Output Termination Assembly in stock
ICS TRIPLEX T9852 (short name 9852) is dual redundant digital output termination assembly for AADvance SIL3 safety instrumented system. It is matched with T9451 digital output module, acting as the field wiring interface between safety I/O card and field actuators such as solenoid valves and shutdown valves. It accepts dual 24VDC field power supply and provides built-in fuses for overcurrent protection.


This termination unit adopts pluggable screw terminal blocks for convenient wiring and maintenance. It supports dual redundant signal path, preventing single power failure from causing safety loop loss. It complies with IEC 61508 SIL3 safety certification. It is discontinued legacy hardware, supplied as surplus or refurbished spare parts for maintenance and retrofit of existing AADvance safety systems.
