Compatible Replacement & Equivalent Models
If the MR-DPD-021 is discontinued, long lead-time, or out of budget, the following models offer functional equivalence or drop-in compatibility:
- MADOKA MR-DPD-020 – Previous generation DO module; same form factor, verify channel count
- MADOKA MR-DPD-022 – Upgraded variant with extended I/O; backward compatible in most racks
- Mitsubishi QY10 / QY40P – Industry-standard 16/32-point transistor DO modules; requires adapter or rewiring
- Siemens SM 322 (6ES7 322-1BH01-0AA0) – 16-point 24 VDC DO; functionally equivalent for most applications
- Omron CJ1W-OD211 – 16-point NPN transistor output; compatible with standard 24 VDC field devices
- Schneider Electric TM3DQ16R – 16-point relay output expansion; suitable for relay-type replacement
Important: Cross-brand replacements require verification of backplane compatibility, signal polarity, and software driver support. Contact support@konmask.com for application-specific guidance.

System Compatibility
The MR-DPD-021 is designed for use within the MADOKA MR-DP Series PLC platform. Confirm compatibility with your specific CPU and rack model before ordering:
- Compatible Racks: MADOKA MR-DP series base units (4-slot, 8-slot, 16-slot)
- Compatible CPUs: MADOKA MR-series CPU modules (verify firmware version)
- Software: MADOKA programming software (ladder/function block); no additional driver required
- Power Supply: Powered via backplane; no separate field power supply needed for logic side
Selection Guide
Use the following criteria to confirm the MR-DPD-021 is the right module for your application:
- Step 1 – Output Type: Confirm whether your field devices require transistor (fast switching, 24 VDC) or relay (AC/DC, higher current) outputs
- Step 2 – Channel Count: Verify required DO point count matches MR-DPD-021 channel capacity
- Step 3 – Rack Slot: Confirm available slot position and rack model compatibility
- Step 4 – Load Current: Check per-channel and total module current ratings against your actuator loads
- Step 5 – Environment: Verify operating temperature, humidity, and vibration ratings for your installation site
- Step 6 – Certifications: Confirm CE/UL/RoHS requirements for your target market or end-customer

Replacement & Compatibility FAQ
Q: Can I replace MR-DPD-021 with a third-party DO module?
A: Functionally possible in some cases, but MADOKA’s proprietary backplane protocol may not be supported by third-party modules. Always test in a non-production environment first.
Q: Is the MR-DPD-021 still in production?
A: Contact us for current availability and lead time. We maintain stock of both new and refurbished units.
Q: What is the difference between MR-DPD-020 and MR-DPD-021?
A: The MR-DPD-021 is the revised version with improved output protection circuitry. Both share the same form factor and are generally interchangeable in the same rack slot.
Q: Do you provide a datasheet or wiring diagram?
A: Yes — email support@konmask.com with your order or inquiry and we will provide the full technical documentation.
Q: Can I return a module if it is not compatible?
A: Yes, within 30 days of receipt in original condition. See our returns policy for details.
