CJ2M-MD211 Omron PLC Pulse I/O Module

Model of Pulse I/O

Modules CJ2M-MD211 (Sinking-type)

CJ2M-MD212 (Sourcing-type )

External Interface 40-pin MIL connector

Pulse Inputs Can be used as normal inputs, interrupt inputs, quick-response inputs, or high-speed

counter inputs.

(Function of each input must be selected in the PLC Setup.)

Input method: Line-driver input or 24-VDC input (selected by wiring)

Normal Inputs 20 max. (10 per Pulse I/O Module)

Input constants: Set in the PLC Setup (0, 0.5, 1, 2, 4, 8, 16, or 32 ms). Default: 8 ms

Interrupt Inputs and

Quick-response

Inputs 8 max. (4 per Pulse I/O Module)

Input signal minimum ON pulse width: 30 s

High-speed Counter

Inputs 4 max. (2 per Pulse I/O Module)

Input method: Differential-phase (4) pulses, pulse + direction, up/down pulses, or

increment pulse

Maximum response frequency: 50 kHz for differential phases or 100 kHz for single

phase

Counting mode: Linear mode or circular (ring) mode

Count value: 32 bits

Counter reset: Phase Z + software reset or software reset

Control method: Target-value comparison or range comparison

Gate function: Supported

Pulse Outputs Can be used as normal outputs, pulse outputs, or PWM outputs. (Function of each

output must be selected in the PLC Setup.)

Output method: Sinking or sourcing transistor outputs (The method is determined by

Pulse I/O Module model.)

Normal Outputs 12 max. (6 per Pulse I/O Module)

Pulse Outputs 4 max. (2 per Pulse I/O Module)

Output method: CW/CCW or pulse + direction (The method is determined by the I/O

wiring and the instructions used in the ladder program.)

Output frequency: 1 pps to 100 kpps (in increments of 1 pps)

Output Mode: Continuous mode (for speed control) or independent mode (for position

control)

Output pulses: Relative coordinates: 0000 0000 to 7FFF FFFF hex (0 to 2,147,483,647
