Versatile FTA

Introduction

The TrustedTM 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 TrustedTM TMR Zone Interface Module T8448. It is also used as the interface for the TrustedTM 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 28V dc.

Features

40 channels per VFTA each configurable as inputs or outputs.

Industrial standard field device connections (2 or 3 wire).

Standard DIN rail compatibility.

Simple installation and connection.

Simple configuration using plug-in fuses and built-in resistors.

18-28Vdc operation.

Field power supply arranged in five groups of eight channels.

Option to supply power from a controllable output for each group.

Fused field power supply per channel.

Versatile FTA T8842

1. Description

The TrustedTM 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 (0-20mA) 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 using the Digital Output configuration shown in this document.

The 40 channels are arranged in five power groups each comprising eight channels. Each channel circuit includes two resistors.

High power 250R 7W 1% resistors to limit short circuit current

Precision 250R 0.25W 0.1% resistors to measure analogue field current

Each circuit contains a set of link positions and can be configured with the following components supplied with the VFTA to enable the user to set the channel for the required input or output configuration.

50mA plug-in TE5 series fuses to protect analogue current inputs

315mA plug-in TE5 series fuses to protect digital inputs

2A plug-in TE5 series fuses to protect digital outputs or act as low resistance links

The first channel of each power group may be configured as a power source for the other seven channels of the group, to allow fire loops to be hard reset by the application.

The cable linking the 40 channels on the TrustedTM Module to the VFTA is terminated at five 10-way connectors (TBG1 to TBG5). The dual 24Vdc power supplies are connected to the VFTA via five 4-way connectors (TBFP1 to TBFP5). Forty 3-way connectors are used for the field loops (TB1 to TB40).
