    FAQs

    Q1: What is the primary function of the 136188-02?

    It is the rear-slot I/O module for the 3500/92 Communication Gateway. It provides the physical communication interfaces (Ethernet RJ-45 and RS485 serial) that enable the 3500 rack to transmit monitored values, module statuses, and alarm information to external systems such as DCS, PLC, and SCADA.

    Q2: What is the difference between 136188-02 and 136188-01?

    The 136188-02 uses RS485 serial communication, supporting long-distance multi-drop bus topology (up to 500m). The 136188-01 uses RS232, limited to short-distance point-to-point connections (≤15m). For new projects, the 136188-02 is recommended to retain scalability

    Q3: Can the 136188-02 be hot-swapped?

    Yes. The module can be installed into or removed from the rack while power is applied, following proper procedures. However, communication with external devices (DCS, PLC, etc.) will be lost when the module is removed.

    Q4: Does the 136188-02 require a companion main card?

    Yes. The 136188-02 must be paired with the 136180-01 3500/92 Communication Gateway main card. The main card occupies the front slot, while the 136188-02 occupies the rear slot directly behind it. Both are required together for complete communication functionality.

    Q5: What is the lifecycle status of the 136188-02?

    The 136188-02 is discontinued (Obsolete) by Bently Nevada, as the 3500 platform has entered sustaining support. It is available through aftermarket suppliers as New Surplus stock. For new installations, Bently Nevada recommends migrating to the System 1 platform.
