Specification

The OMRON CJ2M-MD211 and CJ2M-MD212 are high-performance Pulse I/O Modules designed for the CJ-Series programmable logic controllers. These modules provide a powerful integration of pulse input (high-speed counter) and pulse output (stepper/servo control) capabilities in a single unit, enabling precise motion control for applications such as pick-and-place, packaging, and labeling machinery. With support for up to 4 high-speed counter inputs and 4 pulse output axes per module pair, they offer a cost-effective solution for multi-axis positioning without requiring separate high-speed modules. The MD211 features sinking-type transistor outputs, while the MD212 features sourcing-type outputs, ensuring compatibility with various field wiring standards.

Pulse Input Functionality: Each module can be configured as normal inputs, interrupt inputs, quick-response inputs, or high-speed counter inputs via PLC Setup. Input method (line-driver or 24-VDC) is selected by wiring.
Pulse Output Flexibility: Each output can be used as a normal output, pulse output (for stepper/servo control), or PWM output (for analog-like control). Output method (CW/CCW or Pulse + Direction) is determined by wiring and ladder instructions.
Advanced Motion Features: Supports target-value comparison, range comparison, and gate function for counters. Pulse outputs include linear and S-curve acceleration/deceleration, origin search, and both relative/absolute positioning modes.
High-Speed Performance: Up to 100 kHz pulse output frequency and 100 kHz single-phase input frequency ensure compatibility with modern stepper drives and servo amplifiers.
Compact and Modular: The 40-pin MIL connector allows for dense wiring in control cabinets, and the modules occupy only one slot in the CJ2M CPU rack or expansion rack.
Environmental Ratings: Designed for industrial environments with wide temperature range and standard humidity tolerance, ensuring reliable operation in harsh conditions.
