        Description
        The Bently Nevada 136294-01 Isolated I/O Module is designed to enhance the capabilities of the 3500/62 Process Variable Monitor by providing accurate signal isolation for critical process parameters such as pressure, flow, temperature, and level. Unlike the standard 3500/62 modules that may rely on external barrier connections, the 136294-01 integrates internal terminations, reducing wiring complexity and improving installation efficiency.

        Supporting input signals of ±10 Vdc, isolated 4-20 mA, or 4-20 mA with zener barriers, the 136294-01 delivers precise conditioning of process signals. Its operating range extends from -30°C to +65°C when used with internal or external terminations, and 0°C to +65°C with internal barrier I/O modules, with storage temperatures from -40°C to +85°C, ensuring reliability across a wide range of industrial environments. Compared to modules like the 3500/60, which have limited input flexibility or lower temperature tolerance, the 136294-01 supports broader input configurations and higher environmental resilience.

        The module integrates seamlessly with the 3500/62 Process Variable Monitor, enabling continuous comparison of conditioned signals against user-programmable alarm setpoints. This ensures immediate detection of deviations, protecting machinery from abnormal conditions. The 136294-01 allows programming via the 3500 Rack Configuration Software to perform either current or voltage measurements, supporting multiple industrial I/O requirements in one module.

        When deployed in a Triple Modular Redundant (TMR) configuration, the 136294-01 works alongside two other modules to perform dual voting, reducing the risk of single-point failures and ensuring uninterrupted machinery protection. Compared to other I/O modules without TMR support, such as some 3500/61 variants, the 136294-01 provides higher operational reliability in critical process applications.

        With a humidity tolerance of 95% non-condensing and robust isolation features, the 136294-01 maintains signal integrity in challenging industrial environments. Its compact design and internal terminations also simplify maintenance and reduce installation errors, making it a preferred choice over older isolated I/O modules like the 3500/60 or externally terminated barriers.
