MeloAuto-Trusted PLC & DCS Parts Supplier
The Trusted® T8850 40 Channel Output Field Termination Assembly (FTA) acts as the interface between various Trusted Triple Modular Redundant (TMR) output modules (including both digital and analogue) and field devices. The module provides high reliability, robust performance, and simple integration, making it ideal for industrial applications requiring fault tolerance, redundancy, and secure operation.
Key Features
- 40 Output Channels: Designed to handle 40 output channels per FTA, accommodating a variety of field devices for both analogue and digital outputs.
- Industry Standard Connections: Supports 2-wire connections for field devices, ensuring broad compatibility with various equipment.
- DIN Rail Compatibility: The FTA is compatible with standard DIN rail mounts for easy installation and integration.
- Screw Clamp Terminals: Offers secure connections for both field and power supplies, ensuring reliable operation.
- SmartSlot Connection: Enables ‘one to many’ hot replacement of output modules without system downtime.
- Isolated Groups: The FTA has five isolated groups of eight channels for enhanced protection and noise reduction.
- Field Power LED Indicators: Provides onboard LEDs to indicate the integrity of the field power supply.
- Wide Wire Size Range: Supports a wide range of field terminal wire sizes from 12 AWG to 28 AWG.
