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
