Common 1756-IV16 failures

Failure patterns we regularly see on ControlLogix digital input module hardware like the 1756-IV16:

Input point stuck ON or OFF after a field short or overvoltage on the sensor wiring
Group of inputs dead when the common for that group has been damaged
Slow or missed inputs: input filter components degraded
Removable terminal block pins bent or corroded, giving intermittent points
Module fault LED red at power-up

Repair or replace?

ReplaceI/O cards like the ControlLogix digital input module are the easiest modules to swap: same slot, same wiring, no setup. Replace the 1756-IV16 when a channel is dead and the machine needs to run now. Order the exact 1756-IV16. The catalog number sets the 16-point density and 12/24V DC rating, and a different suffix changes one of them. We have the 1756-IV16 in stock. Order before 5:00 PM Central and it ships the same day.

RepairA single blown point on the 1756-IV16 is a component-level repair (a driver, input channel or on-board fuse), so repair pays when replacements are scarce or you have several cards with a few bad channels each. The two 1756-IV16 symptoms we see most often are “Input point stuck ON or OFF” and “Group of inputs dead”. Every 1756-IV16 repair is fully function-tested and covered by a 1-year warranty.
