Engineering Advantages
- High Channel Density: 16 points per single backplane slot maximizes rack utilization and reduces system footprint.
- Optical Isolation: Full galvanic isolation protects the CPU backplane from field-side transients and ground loops.
- Configurable Input Filter: Software-selectable response time eliminates contact bounce without external hardware.
- Hot-Swap Compatible: Supports RX3i hot-insertion for maintenance without system shutdown (rack-dependent).
- LED Diagnostics: Per-channel status LEDs enable rapid field-level fault isolation without a programmer.
- Series 90-30 Backward Compatibility: Drop-in replacement for legacy Series 90-30 IC693MDL645 installations with minimal re-engineering.
System Architecture & Signal Flow
Field devices (proximity sensors, limit switches, push buttons, relay contacts) connect to the IC694MDL645C terminal block. Each input channel passes through an optical isolator before presenting a logic-level signal to the RX3i backplane bus. The CPU reads all 16 input states within a single I/O scan cycle. Input filtering is configured via the Machine Edition (ME) programming software under the module’s hardware configuration properties. The module occupies one slot in any IC694- or IC695-series backplane.

Technical FAQ
Q: Is the IC694MDL645C compatible with Series 90-30 racks?
A: Yes. The IC694MDL645C is backward compatible with IC693-series backplanes and can replace the IC693MDL645 in most applications.
Q: What programming software is required for configuration?
A: GE Proficy Machine Edition (ME) is required for hardware configuration and I/O mapping. The module is not self-configuring.
Q: Can this module be used with a PACSystems RX7i or RSTi-EP?
A: The IC694MDL645C is designed for the RX3i/Series 90-30 backplane form factor and is not directly compatible with RX7i VME racks or RSTi-EP remote I/O systems.
Q: What is the maximum cable length for field wiring?
A: GE recommends a maximum of 1,000 feet (305 m) for 24VDC discrete input wiring, subject to cable gauge and noise environment.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all modules. Extended warranty options are available — contact us for details.
