    FAQs

    Q1: What is the primary function of the 3500/62-04-00?

    It is a 6-channel Process Variable Monitor that accepts 4-20 mA current inputs from industrial transmitters. It conditions these signals, compares them against user-programmable alarm setpoints (Alert and Danger), and triggers alarms or relay logic to protect machinery. It monitors non-vibration parameters such as pressure, flow, temperature, and level.

    Q2: What is the difference between 136483-01 and 136294-01?

    Both are isolated 4-20 mA I/O modules. The 136483-01 (this configuration) uses External Terminations—field wiring connects to separate external terminal blocks (136595-01 or 136603-01) . The 136294-01 uses Internal Terminations—field wiring connects directly to built-in terminal blocks on the module.

    Q3: Can the 3500/62-04-00 be used in a Triple Modular Redundant (TMR) configuration?

    Yes. For TMR applications, three identical 3500/62 modules must be installed adjacent to each other in the rack. The system uses two types of voting to ensure accurate operation and avoid single-point failures. This configuration provides the highest level of reliability for safety-critical applications.

    Q4: Is the 3500/62-04-00 hot-swappable?

    Yes, the module supports hot-swap capability. However, during replacement, the six-channel process-variable measurement is temporarily invalid while other rack modules continue running normally. Before pulling or inserting the module, bypass active alarms to avoid accidental machine trips.

    Q5: What is the difference between the 3500/62 and the 3500/60/61?

    The 3500/62 is a Process Variable Monitor for pressure, flow, temperature, and level signals (4-20 mA / ±10 Vdc). The 3500/60 and 3500/61 are Temperature Monitors for RTD and thermocouple inputs. The 3500/61 provides recorder outputs (4-20 mA retransmission) per channel, while the 3500/60 does not. Main boards and I/O modules cannot be swapped between these monitor types.
