ICS TRIPLEX T9300(T9851) Digital Output Termination Assembly

Model Number: T9300

Product Type: 3-way I/O Base Unit

Core Function: Provides mechanical mounting and electrical connectivity for up to 3 I/O modules 

(e.g., digital/analog input/output modules) and their associated termination assemblies (TAs).

Key Features: Din rail or panel mountable, connects to T9100 processor base unit or other T9300 

units via direct plug-in or T9310 expansion cables, supports redundant configurations, and includes 

backplane clips for secure interconnection.

Application Scope: Industrial control systems (e.g., emergency shutdown, fire & gas protection) 

requiring modular I/O expansion, compatible with AADvance controller series.

Model Number: T9851

Product Type: Simplex Digital Output Termination Assembly

Core Function: Interfaces 8-channel 24 Vdc digital output signals between AADvance I/O modules 

(e.g., T9451) and field actuators, providing screw terminals, built-in fusing, and polarization keying 

for correct module mating.

Key Features: 8-channel simplex design, commoned wiring, UL/ATEX/IECEx compliant for 

hazardous locations, and integrated overcurrent protection.

Application Scope: Connects digital field actuators (e.g., valves, relays) to AADvance I/O modules in 

safety instrumented systems (SIS) and critical process control setups.

Electrical Ratings: 18–32 Vdc input voltage; 9.6 A maximum backplane current (400 mA per slot).

Physical Dimensions: Approx. 233 mm (H) × 126 mm (W) × 18 mm (D) (excluding connectors).

Weight: 133 g (5 oz) approximate.

Mounting: Compatible with TS35 DIN rails or panel mounting (3 M5 screw holes per unit).

Expansion: Supports T9310 2-meter expansion cables for extending I/O rows; maximum bus length 

(base units + cables) limited to 8 meters.

Channel Configuration: 8 simplex digital output channels.

Electrical Ratings: 18–32 Vdc field voltage; 500 mA maximum backplane current; 10 A built-in fast-

acting fuses (replaceable via T9902).

Wiring Specifications: Accepts 16 AWG conductors (stripping length 6 mm), tightening torque 0.5 

Nm (0.37 ft-lb) for terminal screws.

Polarization Keying: Coding pegs (Key A=3, Key B=1, Key C=1) ensure correct mating with 

compatible digital output modules (e.g., T9451).

Fuse Requirements: Field power input requires 5 A / 125 V slow-blow fuses (compliant with UL 248-

14) for UL/ATEX/IECEx compliance.

Operating Temperature: -25 to +60 °C (-13 to +140 °F) for hazardous environments; -25 to +60 °C 

for non-hazardous environments.

Storage/Transport Temperature: -40 to +70 °C (-40 to +158 °F).

Relative Humidity: 10–95% (non-condensing).

Pollution Degree: 2 (IEC 60664-1).
