Monitored Digital Input Modules
24 VDC
(T3411)
Issue 1, March, 06
Monitored digital input modules provide input sensing for 16 
field input devices. With a line monitor device installed at the 
field switch, monitored digital input modules detect input 
switch status and field wiring open and short circuits. Input 
and line status are reported back to the controller for use in 
application program logic. 
Features
·
Sixteen input points.
·
Fault tolerant operation when connected in parallel with
another module of the same type.
·
Hot-replaceable.
•
Complete, automatic testing of all input circuits.
•
Automatic line monitoring detects open and short field wiring
faults.
·
Individual front panel indicators on each module show the
module’s active/fault and power status, as well as input status 
and line fault status for each point. 
·
2500 volt minimum electrical isolation between field and logic
circuits.
·
TÜV certified, Risk Class 5.
The input module circuits are completely and automatically 
tested, providing a fail-safe interface for safety-critical inputs. 
Two or three monitored digital input modules can be 
connected in parallel to obtain fault tolerant input sensing. 
In these fault tolerant configurations, a failed module can be 
removed and replaced without interrupting the input signals.
