Overview
The T8850 Trusted® 40 Channel Output Field Termination Assembly (FTA) interfaces Triple Modular Redundant (TMR) output modules with field devices. It handles both analogue and digital outputs, providing fault tolerance, redundancy, and reliable operation. Its robust design simplifies integration into industrial control systems while ensuring secure and continuous operation.
Key Features
- 40 Output Channels: Supports 40 independent outputs for analogue and digital signals.
- Industry Standard Connections: 2-wire field connections for broad device compatibility.
- DIN Rail Compatible: Fits standard DIN rails for simple installation.
- Screw Clamp Terminals: Ensures secure connections for field devices and power supplies.
- SmartSlot Connection: Allows hot replacement of output modules without system downtime.
- Isolated Groups: Five isolated groups of eight channels each reduce noise and improve protection.
- Field Power LED Indicators: Monitors field power supply integrity.
- Wire Size Range: Supports 12 AWG to 28 AWG terminals.
