omron CJ1W-INT01 PLC interrupt input unit module

Module Specifications

• Number of Input Points: 8 points

• Input Type: Digital (DC)

• Electrical Isolation: Photocoupler isolation between the input terminals and the internal PLC bus.

Electrical Characteristics (Input Side)

• Rated Input Voltage: 24 V DC

• Operating Voltage Range: 21.6 to 26.4 V DC

• Input Impedance: 3.9 kΩ (Approx.)

• Input Current (at 24V DC): 6 mA (Typical)

• ON Voltage / ON Current: Min. 17 V DC / Min. 3.0 mA

• OFF Voltage / OFF Current: Max. 5 V DC / Max. 1.5 mA

• Response Time:

• ON → OFF: 1.5 ms max. (for interrupt inputs)

• OFF → ON: 1.5 ms max. (for interrupt inputs)

• Note: The fast response time is crucial for its interrupt function.

Interrupt Function

• Interrupt Modes: Supports input interrupt, count-up interrupt, and high-speed counter interrupt.

• Interrupt Response Frequency: Up to 1 kHz (for all 8 points used simultaneously).

Connection and Mounting

• Terminal Type: Removable Spring-clamp Terminal Block (Facilitates wiring and maintenance)

• I/O Points Used: Consumes 8 input points from the CJ-series PLC's maximum I/O capacity.

• Unit Classification: Consumes 1 unit from the CJ-series PLC's maximum number of mounted units.

• Backplane Current Consumption (5V DC): 0.12 A (from the CPU Unit or Power Supply Unit)

Indicator LEDs

• Unit Operation Indicator (RUN): Green, indicates normal unit operation.

• Error Indicator (ERR/ALM): Red, indicates an error such as a watchdog timer error.

• Input Indicators (IN 0 to IN 7): Green, one for each input point, lights when the corresponding input is ON.

Environmental & Mechanical Specifications

• Operating Temperature: 0 to 55 °C

• Storage Temperature: -25 to 65 °C
