The GE IC220MDD840 is a combination discrete I/O and high speed counter module designed for the GE VersaMax Micro PLC platform. With 8 DC inputs (24 VDC), 8 relay outputs, and a dedicated high speed counter channel capable of up to 100 kHz, this module is the go-to choice for engineers who need precise pulse counting and motion feedback in a compact, DIN-rail-mounted form factor.
Where This Product Is Used
The IC220MDD840 is deployed across a wide range of industrial automation applications where accurate, high-speed pulse counting is critical:
- Conveyor & Material Handling: Counting encoder pulses to track belt speed, product position, and throughput on packaging lines.
- CNC & Machine Tool Control: Capturing spindle encoder feedback for speed regulation and position verification.
- Bottling & Filling Lines: Counting fill cycles and container indexing pulses to ensure accurate batch control.
- Printing & Converting Machines: Synchronizing web tension and registration marks via encoder pulse counting.
- Pump & Flow Metering: Interfacing with turbine or paddle-wheel flow meters for volumetric measurement in water treatment and chemical dosing.
- Automotive Assembly: Monitoring rotary encoder signals on torque tools and test rigs for quality assurance.
- Elevator & Hoist Systems: Tracking motor shaft position and speed for safe, precise floor-level control.

Application-Specific FAQ
Q: Can the IC220MDD840 read quadrature (A/B) encoders?
A: Yes. The high speed counter channel supports quadrature mode, allowing direction-aware counting for bidirectional motion applications.
Q: What is the maximum encoder frequency this module can handle?
A: The dedicated HSC channel supports up to 100 kHz input frequency, suitable for most industrial incremental encoders.
Q: Is this module compatible with the IC200 VersaMax Micro series?
A: The IC220MDD840 belongs to the IC220 (VersaMax Micro) family and connects directly to the VersaMax Micro local I/O bus. It is not directly interchangeable with IC200 series modules without a compatible base unit.
Q: Can I use this module as a standalone discrete I/O module without the HSC function?
A: Yes. The 8 DC inputs and 8 relay outputs operate independently of the high speed counter channel and can be used for standard discrete I/O tasks.
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.
Q: Can you supply a Certificate of Conformance (CoC)?
A: Yes, CoC and test reports are available upon request for orders of 3+ units.
