        Overview Manuals Connector Mapping Input Qualification Grouped Diagnosis Product Applications

        Features:

        • High-density acquisition: Sixty-four field states enter one compact CJ-series module position.
        • Four-circuit grouping: Independent common sections help structure the connector wiring when each pair is landed correctly.
        • Connector-specific identity: The Fujitsu/OTAX interface prevents silent substitution with the related MIL-connector model.
        CJ1W-ID261 is used when a CJ or NJ station needs many 24 VDC input points in limited panel space.

        Its two connector interfaces distribute four input circuits, making breakout-board identity and common continuity central to reliable service.

        Commissioning should compare field voltage, connector pin, channel indication and controller variable without assuming that a healthy module can correct a wiring-map error.

        Apter Power can help confirm the Omron CJ1W-ID261 CJ-Series 64-Point DC Input Unit, connector interface and field-wiring scope before quotation.

        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Exact connector: Confirm the installed breakout uses the Fujitsu/OTAX interface assigned to this model.
        • Dual-interface plan: Record which field circuits land on CN1 and CN2 before disconnection.
        • Common pairs: Wire both designated pins for every common and maintain one polarity within the circuit.
        • Label transfer: Preserve point identity so a connector swap cannot exchange whole channel groups.
        • Sensor residual: Confirm two-wire devices can reach the module’s required ON state after their own voltage drop.
        • Off-state current: Investigate leakage paths before treating a persistent input as a logic fault.
        • Response setting: Select filtering from the real signal speed and noise environment.
        • Simultaneous load: Review the active-point pattern for each common under the worst operating condition.
        • Sixteen-point symptom: Start with the affected common and connector section rather than sixteen separate sensors.
        • Thirty-two-point symptom: Inspect the relevant CN interface and field breakout before replacing the PLC unit.
        • Single-point symptom: Trace sensor voltage through the exact connector pin to the controller status.
        • Intermittent bank: Test connector retention and both common pins while the machine reproduces the fault.
        • Machine sensor arrays: Collects large groups of proximity, limit and presence signals.
        • Assembly equipment: Consolidates fixture, clamp and position feedback in one CJ-series position.
        • Material handling: Acquires distributed conveyor and transfer states through connectorized wiring.
        • Panel-density upgrades: Replaces lower-density input arrangements when the complete wiring design is engineered for this connector.
        Description
        CJ1W-ID261 adds sixty-four 24 VDC inputs to a CJ or NJ controller position, concentrating four 16-point input circuits into a narrow connector-style module.

        The Fujitsu/OTAX connector identity of CJ1W-ID261 distinguishes it from the MIL-connector ID262 variant, so the installed breakout hardware and common wiring must be matched by exact model.

        With CJ1W-ID261, response filtering is configured in the controller setup while the field design must respect its per-common simultaneous-on boundary, helping engineers separate configuration problems from wiring or sensor issues.
        Alternative Names
        CJ1WID261 CJ1W ID261 CJ-series 64-point Fujitsu OTAX input unit
        Technical notes
        CJ1W-ID261 accepts either input-supply polarity, but both common pins for each circuit must be wired and kept at the same polarity. A partial common connection can create grouped intermittent inputs that resemble module failure. Verify all four common circuits and the connector pin map before changing PLC logic or replacing hardware.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Sixteen inputs on CJ1W-ID261 disappear together. Which shared point should be checked before the module?
        Inspect both pins of the affected common circuit and its breakout connection. One incomplete common can remove a full channel group.
        Can CJ1W-ID262 replace CJ1W-ID261 if the controller project expects sixty-four inputs?
        Not without a wiring-interface change. The point count is related, but ID261 uses Fujitsu/OTAX connectors while ID262 uses MIL connectors.
        A two-wire sensor never turns CJ1W-ID261 fully on. What electrical boundary matters?
        The sensor must leave enough voltage and load current for the input to cross its ON threshold; otherwise review the device selection or approved bleeder arrangement.
        CJ1W-ID261 works slowly after a project reload. Should the field connector be replaced?
        First compare the configured input response time with the verified project. Filtering can delay a healthy electrical signal without any connector fault.
        Half of CJ1W-ID261 changes to unexpected PLC variables after service. What should controls staff compare?
        Compare CN1/CN2 placement, breakout pin mapping and I/O allocation with the archived drawing before moving individual field wires.
        What should purchasing specify when ordering CJ1W-ID261 for an existing panel?
        State the exact model and confirm whether the Fujitsu/OTAX breakout connectors and cables are already retained, because Omron lists no accessories with the unit.
