Emerson IC694MDL660-BC RX3i 32-Point DC Input Module
A suffix-specific 24 VDC positive/negative logic input module with configurable input filtering.
Overview
IC694MDL660-BC is the BC hardware execution of the PACSystems RX3i thirty-two-point 24 VDC discrete input module. The base IC694MDL660 design accepts positive- or negative-logic field wiring and provides configurable on/off filtering.
The complete IC694MDL660-BC identifier matters because a replacement must preserve both the electrical module type and the installed hardware revision. Field polarity, common wiring, terminal assignment and every configured filter value belong in the exchange record.

Features
Thirty-two 24 VDC field inputs in one RX3i module position.
Positive- or negative-logic operation for the engineered field circuit.
Selectable filtering that balances contact-noise rejection and pulse response.
BC revision identity retained for traceable like-for-like service.
Applications
- Machine status, interlock and permissive inputs in 24 VDC control systems.
- Limit switches, proximity sensors and dry-contact interfaces wired to an RX3i rack.
- Remote RX3i I/O nodes where the approved scanner release supports the module.
Lifecycle
- Export the PAC Machine Edition hardware configuration and record all channel filter values.
- Photograph the IC694MDL660-BC side label, terminal assembly, common conductors and field-supply polarity.
- For time-stamped Sequence of Events service, preserve the documented IC695PNS101 scanner and release requirements.
- After exchange, simulate each input under an approved isolation plan and verify logic, HMI indication, alarms and short-pulse behavior.
FAQ
Why can an IC694MDL660-BC replacement pass a voltage test but still miss machine events?
A restored filter delay may be longer than the original value. The channel settings and the actual pulse width must be compared before the module is released.
What evidence prevents the wrong IC694MDL660-BC revision from being supplied?
A clear side-label photograph, rack slot, firmware baseline and purchase history distinguish the BC execution from another hardware suffix.
How should shared failures across several IC694MDL660-BC points be investigated?
Test the field supply, common conductors, terminal seating and rack power first; a common-path fault can mimic multiple failed channels.
When does an IC694MDL660-BC quotation need the PROFINET scanner details?
Include them whenever the module sits in remote I/O or performs Sequence of Events duties, because scanner type and release affect qualification.
Which acceptance record is appropriate after changing IC694MDL660-BC?
Record each stimulated point, polarity, filter response, controller status, alarm result and restoration of every isolated output or interlock.
