Models 3502E, 3503E, and 3505E can
self-test to detect stuck-ON conditions
where the circuitry cannot tell whether
a point has gone to the OFF state. Since
most safety systems are set up with a
de-energize-to-trip capability, the
ability to detect OFF points is an important feature. To test for stuck-ON
inputs, a switch within the input
circuitry is closed to allow a zero input
(OFF) to be read by the optical isolation
circuitry. The last data reading is frozen
in the I/O communication processor
while the test is running.
All TMR digital input modules support
hot-spare capability, and require a separate external termination panel (ETP)
with a cable interface to the Tricon

backplane. Each module is mechanically keyed to prevent improper installation in a configured chassis.
