Configured for 24 VDC discrete signal acquisition in CJ-series PLC systems, the Omron CJ1W-ID262 (CJ1W-ID262 DC Input Unit) provides 64 digital input channels through two 40-pin MIL connectors. The unit supports PNP/NPN input devices, uses four 16-point common circuits, and allocates 4 words in the CJ I/O system. Official Omron specifications define a 20.4 to 26.4 VDC permitted input range and 90 mA maximum internal current consumption.

Technical Identifier Matrix

The official Omron product record identifies CJ1W-ID262 as a 64-input, 24 VDC digital input unit with two MIL connectors.

Hardware Specifications

The physical dimensions are from Omron's product record: 90 mm height, 31 mm width, and 83.6 mm depth. The catalog also specifies 110 g maximum unit weight.

PLC Backplane and I/O Density

CJ1W-ID262 is a high-density basic I/O unit for the CJ I/O Bus, providing 64 discrete input points in a 31 mm-wide module. The input circuits are arranged as four groups of 16 points with one common per group. At 24 VDC, Omron specifies a maximum simultaneous ON loading of 8 points per common, or 50%.

The unit accepts both PNP and NPN input devices, provided the same polarity is used for inputs sharing a common. Its configurable digital filter can be set from 0 to 32 ms to suppress unwanted external signal transitions.

Package Contents & Ordering Information

• 1x Omron CJ1W-ID262 DC Input Unit
• 1x CJ-series 64-point input module
• MIL connector plugs are not included
• External connector wiring requires compatible 40-pin MIL connector hardware
• Connector-to-terminal conversion options are available separately, including Omron XW2K series conversion units.

Field Installation Guidelines

• Mount the CJ1W-ID262 in the CJ-series PLC rack according to the applicable CJ-series hardware installation manual.
• Verify that the PLC backplane and CPU configuration support the installed Basic I/O Unit.
• Apply a 24 VDC input supply within the specified 20.4 to 26.4 VDC operating range.
• Keep the input supply within the specified voltage range during normal and transient operating conditions.
• Connect the two 40-pin MIL interfaces using correctly keyed and rated connectors.
• Maintain the same signal polarity for inputs belonging to the same common circuit.
• Do not exceed 8 simultaneously ON input points per 16-point common group at 24 VDC.
• Configure the digital input filter only as required by the signal characteristics; excessive filtering increases signal recognition delay.
• Separate discrete input wiring from high-current switching and high-frequency power wiring where practical.
• Use appropriate shield termination and grounding practices when the connected field devices or cable installation require noise control.
• Confirm the PLC I/O allocation because the CJ1W-ID262 occupies 4 words in the CJ I/O system.

Frequently Asked Questions

• Q: What input voltage does the CJ1W-ID262 require?

  A: The rated input voltage is 24 VDC, with a permitted input voltage range of 20.4 to 26.4 VDC.

• Q: How many digital inputs are provided?

  A: The module provides 64 digital input channels arranged as four groups of 16 inputs, with one common circuit assigned to each group.

• Q: What connector does the CJ1W-ID262 use?

  A: It uses two 40-pin MIL connectors for field I/O connections. Omron specifies that the connector plug is not included with the unit.

• Q: What are the physical dimensions of the module?

  A: The official dimensions are 9.0 cm x 3.1 cm x 8.36 cm for height, width, and depth respectively.

• Q: What is the maximum internal current consumption?

  A: Omron specifies 90 mA maximum internal current consumption for the CJ1W-ID262. This value is used for PLC power-budget calculations.

• Q: Can the input polarity be configured for PNP and NPN devices?

  A: Yes. The module supports PNP/NPN input devices. Inputs sharing a common must use the same polarity arrangement for that common circuit.

• Q: What input response time is specified?

  A: Both ON and OFF response times are specified at 8.0 ms maximum. The input filter can be configured between 0 and 32 ms through the applicable setup.

• Q: How many inputs can be simultaneously ON?

  A: At 24 VDC, the specified simultaneous ON limit is 50%, corresponding to 8 ON points for each 16-point common circuit.
