Transgression of the slew rate limits identified above may lead to channel
failure resulting from diagnostics otherwise designed to verify that channels are
operating within their defined safety accuracy.
T9801/2/3 Termination
Assemblies for Digital Inputs
There are three termination assemblies for use with digital input modules that
supply simplex, dual and triple modular redundant configurations.
A T9801 termination assembly is for a simplex application and has
terminations for 16 non-isolated digital inputs, it has connections for one
T9401 or T9402 digital input module. The T9802 and T9803 termination
assemblies support 16 isolated digital inputs for dual and triple modular
redundant arrangements of digital input modules.
Illustrated is the T9802 dual termination assembly.

A replaceable fuse protects each channel from field faults. Fuses can be replaced
without removing a module or the termination assembly.
