Bently Nevada 3500/60 133819-01 Temperature Monitor I/O Module

Configured for high-precision temperature data acquisition in the 3500 Machinery Protection System, the Bently Nevada 133819-01 (3500/60 Temperature Module) provides direct physical/electrical execution. This 6-channel component functions as the physical interface layer that routes and processes signals from field-mounted Resistance Temperature Detectors (RTDs) and Thermocouples (TCs) into the main monitoring rack.

Hardware Specifications

Machinery Monitoring & Cross-Talk Suppression

The 6-channel architecture uses a 16-bit analog-to-digital converter to track thermal variations on bearings, windings, and process loops. Because this specific iteration is a non-isolated hardware design sharing an internal common ground, the layout incorporates advanced hardware filters to maximize cross-talk suppression between adjacent probe lines. This design prevents high-frequency electromagnetic interference (EMI) from motor circuits or turbine environments from generating measurement drift, maintaining signal integrity over the 250 ms continuous conversion cycle.

Frequently Asked Questions

Q: Can a single 133819-01 module accept mixed RTD and Thermocouple field lines concurrently?

A: Yes. Each of the 6 independent channels is individually programmable via the 3500 Rack Configuration Software. You can configure any combination of supported 3-wire/4-wire RTDs and standard Thermocouples across the terminal matrix.

Q: What restrictions exist regarding hot-swapping the 133819-01 component?

A: This rear I/O module does not support hot-swapping while the 3500 chassis backplane is energized. Power to the rack must be completely isolated before extracting or inserting the card to avoid transient power surges that could damage the unisolated internal multiplexing circuits.

Field Installation Guidelines

• Chassis Card Guide Alignment: Insert the module into the rear slot of the 3500 rack directly behind the corresponding 3500/60 monitor module. Press firmly until the multi-pin array fully engages with the passive backplane. Secure the hardware by completely tightening the two integrated mechanical panel fasteners.
• Shield Grounding Regulations: Terminate all field sensor cable shields at the single-point instrumentation ground rail inside the monitoring panel. Do not ground shields at both ends, as the non-isolated architecture makes the loop highly susceptible to circulating ground currents.
• Cable Pathway Rules: Route low-voltage RTD and Thermocouple conductors through dedicated instrument wireways. Maintain appropriate physical clearance from high-voltage alternating current (AC) power lines and variable frequency drive cables to minimize noise injection.
• Thermal Management Clearances: Ensure that the enclosure layout does not block vertical convection airflow through the 3500 rack structure, keeping localized ambient temperatures strictly below the +65 deg C operating threshold.
