Description
The Trusted Versatile Field Termination Assembly (VFTA) is designed to act as the main interface between field devices associated with the detection and suppression of fire and gas hazards, and the Trusted TMR Zone Interface Module T8448.
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 40V dc.
The 40 channels are arranged in five power groups each comprising eight identical channels. Each power group is supplied from dual 24V dc feeds which are commoned via diodes on the VFTA. The supply is then fed to each channel within the group.
The supply voltage to the field is fed via a 315mA fuse. The incoming signal (0-20mA) from the field device is fed through a 50mA fuse which effectively limits the input signal. The voltage developed across an input 250R resistor (high precision 0.1%) is used by the input module to detect the field device status.
The cable linking the 40 channels on the input module to the VFTA is terminated at five 10-way connectors. The dual 24V dc power supplies are connected to the VFTA via five 4-way connectors. Forty 3-way connectors are used for the field loops.
The VFTA is designed to be mounted on either of the TS32 or TS35 DIN rails in the horizontal or vertical positions as required.
Features
Forty input channels per VFTA
Industry standard field device connections (3-wire)
Standard DIN rail compatibility
Simple configuration using plug-in fuses
Simple installation and connection
24V dc operation
Fused field power supply per channel
Designed for use with current sinking and sourcing field devices

DPA53 series monitor for ultra-thin (17.5mm) rail mounting type, function: phase failure protection, phase sequence protection, voltage unbalance protection, adjustable set value undervoltage protection. It is suitable for the protection of the distribution system installed in the cabinet.
I. Overview
DPA53 series three-phase relays for three-phase or three-phase four-wire power supply for the monitor. This series of products measuring their own supply voltage, regenerative voltage, with phase sequence protection, lack of protection, undervoltage protection and other functions, N-type products with zero line disconnection protection. DPA53 series monitor for the ultra-thin (17.5mm) rail mounting type, suitable for installation of the cabinet to install the power distribution system protection, such as: distribution cabinet, distribution box, electric control box, machine tools and other equipment.
220 ~ 277VAC ± 15% (phase voltage) Model: DPA53AM48N
Phase sequence monitoring: When the three-phase power monitor power, such as the phase sequence is normal, the relay can pull.
Phase loss monitoring: When the three-phase power monitor power, each phase power is normal, the relay can pull.
Undervoltage protection: When the three-phase power supply line voltage is lower than the set value, then the relay release protection; when the voltage recovery, the relay back to work properly.
N line disconnection protection: DPA53AM23N and DPA53AM48N is suitable for three-phase four-wire system power monitor, the two products in the N line when the relay release.
