ICS Triplex T8842C Versatile Field Termination Assembly

The ICS Triplex T8842C belongs to the Trusted™ series from Rockwell Automation and supports high-availability architectures across critical control environments. It works alongside Trusted TMR modules to manage both digital and analog field connections for fire, gas, and valve-monitoring systems. Its flexible 40-channel layout, efficient wiring design, and robust power distribution structure make it ideal for complex safety applications.

Reliable Field Connectivity with TMR Architecture

The T8842C VFTA connects directly to the Trusted T8448 TMR Zone Interface Module and the T8449 TMR Valve Monitor Module. Each channel integrates fused power distribution and configurable wiring options, which improve system protection while maintaining consistent signal integrity. Users deploy this assembly in hazardous-area detection systems that require dependable communication between field devices and the Trusted processor system.

Key Features

• Supports 40 configurable I/O channels for broad field-device integration
• Allows 2-wire or 3-wire analog and digital signal connections
• Organizes channel power in five groups of eight for efficient power routing
• Includes plug-in fuses and built-in resistors for fast field installation
• Accepts 18–28 VDC supply for flexible power infrastructure
• Mounts directly onto standard DIN rails to simplify panel design
