Monitored Guarded output modules provide Guarded control
and line monitoring for sixteen field loads. Three types of
modules are available for interfacing to outputs powered from
24 VDC, 110 VAC, or 120 VDC field power supplies. These
modules are called Guarded because each module's dual-
redundant design ensures that no single fault within the
module will inadvertently apply power to an output. These
modules also monitor the output field wiring for open and
short circuit faults. Individual output line status is available
to application programs.
Features
· Sixteen Guarded outputs (in two groups of eight).
• Fault tolerant operation when connected in parallel with
another module of the same type.
• Hot-replaceable.
• Complete, automatic testing of all output circuits.
• Automatic line monitoring detects open and short field wiring
circuits.
• Individual front panel indicators on each module show module
fault/active status and shutdown state; additional indicators
show output status and load/fuse fault for each point.
· Fuses accessible from front panel.
• 2500 minimum electrical isolation between field and logic
circuits.
· TÜV certified, Risk Class 5.
Each module's triplicated Safetybus interface ensures that no
Regent system failure will inadvertently apply power to an
