GE IC695MDL664 PACSystems RX3i Smart Digital Input Module
A 16-point, 24 VDC positive-logic input module with per-module filter selection and advanced field-circuit diagnostics.
Function, System Position and Selection Boundary
IC695MDL664 connects 24 VDC field inputs to a PACSystems RX3i controller through a Universal PCI backplane slot. The module groups its 16 points as two groups of eight and reports input state to the PLC while supporting diagnostic checks that ordinary discrete input modules do not provide.
The official RX3i data identifies selectable on and off filtering from 0.5 to 100 ms. Selection must reflect the signal: fast transitions need a short value, while contact bounce or electrical noise may justify a longer filter.

Backplane and diagnostics
Diagnostic Input Commissioning
The diagnostic functions only help when the field circuit, terminal block and controller configuration are aligned. Record the existing filter and diagnostic setup before replacing a module.
Field circuit
Confirm 24 VDC positive-logic wiring and the common arrangement.
Configuration
Transfer the documented filter and diagnostic selections.
Acceptance
Exercise each point and verify state plus expected diagnostic behavior.
Installation and Acceptance Sequence
- Record slot, terminal block, point references and filter selection.
- De-energize field and rack power before disturbing wiring.
- Seat the module and terminal block without changing point order.
- Restore power, test every input and confirm diagnostic indications.
FAQ
Which backplane position is valid for IC695MDL664?
The official RX3i table restricts the module to a Universal PCI slot; it occupies one slot.
How should the input filter for IC695MDL664 be selected?
Choose one documented on/off value from 0.5 to 100 ms for the signal characteristics and preserve the approved project setting.
What terminal block belongs with IC695MDL664?
Use IC694TBB032 or IC694TBS032 as specified; the block is ordered separately.
Which checks distinguish IC695MDL664 from a basic input module?
Review open-wire, short-to-negative, input-pulse-test and short-to-positive diagnostics in addition to point state.
What should be proven after replacing IC695MDL664?
Prove all 16 inputs, common wiring, configured filters and the diagnostics used by the application.
