Chapter 2 Installation Instructions
The adapter also monitors the input data paths and can detect faults within
each input channel. A visual indication of the module status and individual
channel status is provided by an array of front panel indicators.
The range of termination assemblies can accept one or two input modules.
Each assembly provides passive signal load termination and fuse over-voltage
protection on each input channel. The system provides flexible and scalable
input connectivity through mating termination assemblies with the relevant
number of input modules.
Field Wiring of Digital Input Termination Assemblies
The termination assembly routes each digital input through a circuit. See
. The input channel is protected with a 50 mA fuse. When an extreme
over-voltage is applied to the input, the fuse blows. Each digital input signal is
terminated by 5.11 k
high reliability load and is fed to the input circuit of the
input module.

IMPORTANT
If a fault occurs during normal operation in a duplex-configured
system, an input module can be removed and replaced without
disrupting the flow of input data.
