CJ2M-MD211 Pulse I/O Module NPN 10 Inputs 6 Outputs MIL Connector | Omron

The Original New Omron CJ2M-MD211 is a dedicated pulse I/O module for CJ2M CPU units, providing high-speed positioning and motion control capabilities in a compact 20 mm width. Featuring 10 NPN inputs (four configurable as interrupt/quick-response inputs and two as high-speed counter inputs) and 6 NPN outputs (two pulse outputs, two PWM outputs, and two standard transistor outputs), this module enables multi-axis positioning, high-speed counting, and PWM control for demanding machine automation applications. The MIL 40‑pin connector (not included) provides high-density wiring for space‑efficient control panels.

Core Engineering Highlights:
10 NPN inputs (4 interrupt/quick-response + 2 high-speed counter inputs) | 6 NPN outputs (2 pulse, 2 PWM, 2 standard) | 2 kHz max pulse output frequency | Up to 4 axes positioning (2 modules max) | High-speed counter: 50 kHz differential / 100 kHz single-phase | MIL 40‑pin connector interface | 90 × 20 × 66.3 mm | 70 g | CJ CPU Bus connection | CPU hardware V2.0 or higher required
