Primary Applications
Features:
- 40 channels per VFTA each configurable as inputs or outputs
- Industrial standard field device connections (2 or 3 wire)
- Field power supply arranged in five groups of eight channels
The Trusted Versatile Field Termination Assembly (VFTA) T8842 is primarily designed to act as the main interface between field devices associated with the detection and suppression of fire and gas hazards, and the Trusted Triple Modular Redundant (TMR) Zone Interface Module T8448.
It is also used as the interface for the Trusted TMR Valve Monitor Module T8449, for which digital outputs to solenoid valves alternate with valve position analogue inputs. Each channel of the VFTA is configurable to enable a variety of field devices to be connected. These include devices generating both analogue and digital input signals, and output devices requiring a digital signal at up to 28 Vdc.
The T8842 ICS triplex Trusted Versatile Field Termination Assembly may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The Trusted Versatile FTA T8842 provides termination for a maximum of 40 input or output channels from various types of field devices. The input signals may be analogue (0 mA to 20 mA) or digital, whilst output signals are digital only with the T8448 Zone Interface Module. However, the Versatile FTA T8842 may be used with the T8480 Analogue Output module.
- Fire and Gas Systems: Serves as the primary interface for sensors and devices used to detect and suppress fire and gas hazards.
- Safety Instrumented Systems (SIS): SIS is crucial for safety-critical processes in oil and gas refineries or chemical plants; any failure is absolutely unacceptable.
- Valve Monitoring: Used as the interface for the Trusted TMR Valve Monitoring Module T8449, processing digital outputs from solenoid valves and analog inputs for valve position.
- Wide Range of Industrial Automation Applications: Deployed in power plant DCS monitoring, robot control, and building automation, among other areas.
