TrustedTM 60 Channel Analogue Input FTA - T8832
GENERAL ASSEMBLY
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.
