ICS Triplex T8850 Trusted 40 Channel Analogue (or Digital) Output Field Termination Assembly (FTA)

Product Description

The ICS Triplex T8850 module is a Field Termination Assembly (FTA) designed for Rockwell Automation’s ICS Triplex Trusted safety and control systems. ICS Triplex is renowned for providing highly reliable and fault-tolerant control systems, particularly for critical applications in process industries, such as emergency shutdown (ESD), fire and gas (F&G), and turbomachinery control (TMC).

The T8850 FTA serves as a passive interface between the field wiring (from sensors and actuators) and the corresponding output modules within the Trusted system’s chassis. Its primary role is to provide convenient and robust termination points for a large number of analog or digital output field devices.

Key functions and features of the T8850 include:

• High Channel Density: It provides termination for up to 40 output channels, consolidating wiring from multiple field instruments.
• Simplified Wiring: It uses screw clamp terminals for easy and secure connection of field and power wires.
• Robust Design: Built for industrial environments, ensuring reliable connections and protection for critical safety applications.
• Compatibility: Designed to work seamlessly with specific output modules (e.g., T8451, T8461, T8471, T8480, etc.) in the ICS Triplex Trusted system.
• Diagnostic Features: It may include LEDs for on-board indication of field power supply, which can assist in troubleshooting.
• Flexible Mounting: Designed for standard DIN rail mounting (TS32 or TS35) in horizontal or vertical positions.

In essence, the T8850 acts as a bridge that simplifies the physical wiring from numerous field devices to the sophisticated output modules of the Trusted system, maintaining the integrity and reliability crucial for safety-instrumented systems.
