Guarded Analog Output Modules
4 to 20 mA
(T7480)
Issue 1, March, 06
Guarded analog output modules provide 4 to 20 mA current
outputs for a maximum of six user loads per module. These
modules are called Guarded because the module's dual-
redundant design ensures that no single fault within a
module will inadvertently change an output's signal. The
module's triplicated Safetybus interface ensures that no
Regent system failure will inadvertently affect the output
signal. Extensive fault detection and annunciation of critical
redundant circuits ensures the modules will continue to
operate in a fail-safe manner.
Features
· Six 4 to 20 mA output circuits.
· Dual, high resolution, 12-bit D/A converters per output.
· Fault tolerant operation when connected in parallel with
another module of the same type.
· Hot-replaceable.
· Comprehensive self-testing of all critical circuits.
· Front panel indicators on each module show active/fault,
shutdown, and on status.
· 2500 volt minimum electrical isolation between field and logic
circuits.
· TÜV certified, Risk Class 5, non-interfering.
Two Guarded output modules can be connected in parallel to
obtain fault tolerant control of current to the loads. In this
parallel module configuration, either module can be removed
and replaced while the other Guarded module continues to
control the loads without interruption.
