Proven Application Environments
- Variable Speed Drive (VSD) Control Panels — Extend drive I/O for start/stop, fault reset, and speed reference signals without external relay modules.
- Conveyor & Material Handling Systems — Interface proximity sensors, limit switches, and solenoid outputs directly through the drive option slot.
- HVAC & Pump Control — Integrate building automation system (BAS) digital commands with PowerFlex 753/755 drives in fan and pump applications.
- Water & Wastewater Treatment — Reliable 24V DC I/O in wet-area control panels where signal isolation and noise immunity are critical.
- OEM Machine Builders — Reduce panel footprint and BOM cost by consolidating I/O into the drive option slot rather than standalone I/O modules.
- Retrofit & Upgrade Projects — Drop-in replacement for earlier 20-750-2262 series revisions in existing PowerFlex 750 installations.
Engineering Advantages
- Backplane Integration: Communicates directly over the PowerFlex 750 internal option bus — no additional fieldbus wiring, no address configuration, zero latency overhead versus external I/O modules.
- Sink/Source Flexibility: All 6 digital inputs are configurable for NPN (sink) or PNP (source) wiring, accommodating both European and Asian sensor standards on the same module.
- Solid-State Outputs: Transistor outputs eliminate mechanical wear, reduce maintenance intervals, and support high-cycle applications (conveyor indexing, valve actuation).
- Optical Isolation: Input circuits are optically isolated from the drive logic, protecting the drive CPU from field-side transients and ground loops.
- Hot-Swap Capable: Supports drive power-on module insertion per PowerFlex 750 option module guidelines, minimizing planned downtime during maintenance.
- Firmware Transparent: Recognized automatically by PowerFlex 750 firmware; parameters appear in the drive parameter tree without manual configuration files.
System Architecture & Signal Flow
The 20-750-2262C-2R occupies one peripheral option slot (Ports 4–6) on the PowerFlex 750 drive chassis. Upon insertion, the drive firmware enumerates the module and maps its I/O points to the drive’s internal parameter database. A host PLC (e.g., Allen-Bradley ControlLogix or CompactLogix) accesses these I/O points via the drive’s primary network adapter (EtherNet/IP, DeviceNet, or PROFIBUS) using standard drive I/O messaging — no separate I/O scanner required.
Typical signal flow: Field sensor → 24V DC input terminal → optical isolator → drive parameter register → PLC tag (via network adapter) → PLC logic → drive parameter register → solid-state output → field actuator.

Technical FAQ
Q: Is the 20-750-2262C-2R compatible with PowerFlex 753 and PowerFlex 755?
A: Yes. The module is compatible with all PowerFlex 750 Series drives that have available peripheral option slots (Ports 4–6). Verify available slots in your drive’s hardware documentation before ordering.
Q: Can I use this module with a PowerFlex 700 drive?
A: No. The 20-750-2262C-2R is designed exclusively for the PowerFlex 750 Series option slot architecture. It is not compatible with PowerFlex 700 or earlier series.
Q: How many option modules can I install simultaneously?
A: The PowerFlex 755 supports up to 8 option slots (Ports 1–8); the PowerFlex 753 supports fewer. The 20-750-2262C-2R occupies one slot. Consult your drive’s installation manual for slot availability and power budget constraints.
Q: Does this module require a separate 24V DC power supply?
A: The module draws its logic power from the drive’s internal option bus. Field-side 24V DC for input/output circuits must be supplied externally by the panel’s 24V DC power supply.
Q: What is the difference between revision 2R and earlier revisions?
A: Revision designations reflect Rockwell Automation’s internal engineering change notices (ECNs). Functional I/O specifications remain consistent across revisions. For revision-specific change details, consult Rockwell Automation’s product change notification (PCN) database or contact our technical team.
Q: Can Konmask provide a datasheet or wiring diagram?
A: Yes. Contact support@konmask.com and we will provide the relevant Rockwell Automation publication (750-IN001 or equivalent) along with application-specific wiring guidance.
