TrustedTM 60 Channel Analogue Input FTA - T8832

DESCRIPTION

The Trusted Channel is designed to act as the main interface between a field device generating a digital signal and the Trusted T8432.
The field supply is derived from dual 24V dc feeds, which are ‘commoned’ via diodes on the FTA. The supply is then fed to each channel. Channel 0 on the Trusted future to provide monitoring of the field power supply.
The supply voltage to the field is fed via a 50mA fuse. The incoming signal from the field device is developed across a 250R resistor, then connected to the appropriate input circuit on the Input Module. Line monitoring components (if required) provide the necessary thresholds used by the input module to detect the field loop/device status, i.e. open/short circuit, alarm etc.
The cable linking the 60 channels on the input module to the FTA is terminated at a 96-way socket. The dual dc power supplies are connected to the FTA via a single 4-way connector. Ten 12-way connectors are used for the field loops.
The FTA is designed to be mounted on either of the TS32 or TS35 DIN rails in the horizontal or vertical positions as required.
