DC Guarded Digital Output Modules
24 VDC, 48 VDC and 120 VDC
(T3461A, T3462A and T3468A)
Issue 1, March, 06
DC Guarded output modules provide Guarded switching of 
user-supplied DC voltages to a maximum of eight field loads. 
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. 
Extensive fault detection and redundant critical circuits 
ensure that each module operates in a fail-safe manner. 
Features
·
Eight Guarded output circuits configured as two separately
powered groups of four circuits each.
·
Fault tolerant operation when connected in parallel with
another module of the same type.
·
Hot-replaceable.
·
100% self-testing of all critical circuits.
·
Individual front panel indicators on each module show active
and fault, shutdown state, blown fuse, and output on/off status 
(logic side). 
·
2500 volt minimum electrical isolation between field and logic
circuits.
·
TÜV certified, Risk Class 5.
Two Guarded output modules can be connected in parallel to 
obtain fault tolerant control of power to 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.
