GENERAL ASSEMBLY
DESCRIPTION
The Trusted
TM Output Power Distribution Unit is designed to provide
24-120V dc for use with Trusted TM sourcing output modules, e.g. T8451 and
T8471, 24V dc and 120V dc Digital Output Modules respectively, and T848X
Analogue Output Modules obtaining their 0V reference via Trusted
TM
Versatile Field Termination Assemblies (VFTAs).
The Unit is designed to be mounted on a DIN rail above the relevant output
module I/O connectors.
The Trusted TM Output Power Distribution Unit is designed to distribute the
+ve field loop power for the 24-120V dc range of Trusted TM sourcing output
modules. The output 0V reference and 0V power return is via the Trusted TM
Versatile Field Termination Assemble (VFTA).
Up to three output modules may be supported providing the total load does
not exceed the maximum rated capacity of the Unit.
Each supply stud is capable is capable of supplying the maximum rated
capacity and can be used in single or dual configuration as required. Dual
configuration may be used where the supply is fed via blocking diodes.
Where the total load current for three Trusted TM Analogue or Digital Output
Modules is less than 6A, the supply can be fed via the on-board blocking
diodes through terminal block TB1. If this method of supply is used,
insulating sleeves must be fitted to the redundant power studs.
