Product Type: Expander Interface Module

Category: I/O Modules

Gross Weight: 0.80 kg

The T8850 is a high‑density field terminal assembly designed for Triconex TMR safety control systems.

This module acts as an expander interface to connect the main controller with field output devices.

It combines analog and digital output capabilities in a single unit to reduce cabinet space usage.

The T8850 accepts two wide voltage ranges to fit different power schemes in global industrial sites.

Each channel can drive up to 2A of current, supporting a variety of actuators and field loads.

Hazardous location certifications allow installation in potentially explosive industrial environments.

Sturdy terminal blocks ensure reliable wiring with specified torque and standard industrial wire sizes.

Its robust build maintains stable performance in harsh plant conditions with electrical noise present.

The T8850 integrates smoothly into TMR architectures to support safe and reliable output operation.

The T8850 serves as a 40‑channel analog and digital output field terminal assembly (FTA).

It functions as an expander interface module within ICS Triplex and Triconex safety systems.

Supply voltage ranges are 18–32 Vdc and 18–60 Vdc for flexible on‑site power compatibility.

Each output channel supports a maximum continuous current of 2A for field device control.

Total maximum current for the entire module is limited to 40A under full load conditions.

Recommended terminal torque is 0.5 N·m to ensure secure and long‑lasting wire connections.

Compatible wire sizes range from 30 AWG to 12 AWG, or 0.05 mm² to 2.5 mm².

The module holds certifications for ordinary locations, hazardous locations, ATEX, and IECEx.

These qualifications support safe deployment in oil, gas, and chemical processing environments.

The T8850 has a net weight of 0.8 kg, enabling lightweight and dense rack installation.

Its high channel count lowers overall system cost and simplifies cabinet layout design.

Mount the T8850 in a protected cabinet close to field equipment for shorter cable runs.

Confirm the applied supply voltage falls within 18–32Vdc or 18–60Vdc before powering the unit.

Select wires between 30 AWG and 12 AWG for all input and output field connections.

Tighten each terminal screw to a torque of 0.5 N·m for stable electrical contact.

Route signal and power cables away from high‑voltage sources to avoid electromagnetic interference.

Ensure proper system grounding to meet hazardous location and certification requirements.

Insert the module firmly into its assigned rack slot and secure it to the backplane connector.

Power on the system and verify each channel to confirm proper operation of the T8850.

Do not exceed 2A per channel or 40A total to prevent overheating and module damage.

Keep the installation area clean and dry to maintain certification compliance over time.
