Product introduction
The Bently Nevada 3500/22-01-01-00 138607-01 is an entry-level 4-channel temperature monitoring module, designed to provide reliable thermal data for cost-sensitive industrial applications. As a variant of the standard 3500/22-01-01-00, this model (138607-01) incorporates basic surge protection and enhanced accuracy, making it suitable for monitoring non-critical machinery such as auxiliary pumps, fans, and small motors—where temperature trends are essential but ultra-precision is unnecessary.
Unlike the 3500/65 145988-02, which focuses on executing protective actions via relays, the 3500/22-01-01-00 138607-01 specializes in temperature data acquisition. It feeds thermal measurements to controllers like the 3500/53 133388-01, which then uses this information to trigger actions via modules such as the 3500/65 145988-02. This division of labor—sensing vs. acting—makes it a foundational component in distributed monitoring systems.
Powered by the 3500/91 190782-01 supply, the module operates reliably in harsh environments, from factory floors to outdoor enclosures. Its compact 1-slot design maximizes rack space efficiency, while its support for common sensor types (PT100 RTDs, Type K/J thermocouples) ensures compatibility with existing installations—offering a balance of functionality and affordability.
Core advantages and technical highlights
Enhanced entry-level accuracy: The 3500/22-01-01-00 138607-01 improves on the standard 3500/22-01-01-00 with ±0.3°C accuracy for RTDs (0°C to +300°C), exceeding the typical ±0.5°C of basic modules. This allows it to detect subtle trends—such as a 0.5°C per hour rise in a motor bearing—enabling earlier warnings than less precise alternatives.
Basic surge protection: Unique to the 138607-01 variant, 2kV surge protection per channel safeguards against electrical transients, a feature absent in the standard model. This is critical for installations near high-voltage equipment, preventing sensor damage and data loss—addressing a vulnerability that the 3500/65 145988-02 (focused on relay outputs) does not cover.
Space-efficient design: Occupying just 1 rack slot, the module optimizes limited rack space, allowing integration with other 1-slot components like the 3500/53 133388-01. This contrasts with the 3500/65 145988-02’s 2-slot footprint, making it ideal for small-scale systems where space is at a premium.
Simplified integration: The module streams temperature data to the 3500 backplane, enabling seamless integration with controllers and relay modules like the 3500/65 145988-02. For example, it can send bearing temperature data to the 3500/53 133388-01, which then triggers a “Danger” relay via the 3500/65 145988-02 if thresholds are exceeded—creating a closed-loop protection system.

Typical application scenarios
In a wastewater treatment plant, the 3500/22-01-01-00 138607-01 monitors 4 submersible pump motors using PT100 RTDs. It sends temperature data to the 3500/53 133388-01 controller, which compares readings to predefined thresholds. When a motor’s temperature exceeds 90°C, the controller triggers Relay 5 in the 3500/65 145988-02, activating a warning light and shutting down the pump—preventing burnout. The module’s surge protection ensures reliable operation despite electrical noise from the plant’s pumps.
At a food processing facility, the module tracks temperatures of 2 conveyor bearings (Type K thermocouples) and 2 refrigeration units (4-20 mA transmitters). Its 1-slot design fits in a compact rack alongside the 3500/53 133388-01 and a 3500/65 145988-02. If refrigeration temperature drops below 2°C, the controller uses the 3500/65 145988-02 to trigger an alarm (Relay 2) and activate a backup cooling unit (Relay 3)—maintaining food safety compliance.
In a small manufacturing plant, the 3500/22-01-01-00 138607-01 monitors a hydraulic system’s oil temperature (PT100) and motor winding temperature (Type J thermocouple). Paired with a 3500/44-01-00 (vibration) and 3500/65 145988-02, it enables conditional shutdowns: the controller shuts down the system via Relay 10 only if both temperature exceeds 85°C and vibration exceeds 10 mm/s—reducing false shutdowns during startup.

Power off via the 3500/91 190782-01 before installation. Secure with screws torqued to 0.6 Nm, verifying backplane alignment. Connect sensors to terminal blocks: use 3-wire RTD connections to minimize error, and shielded cables for thermocouples to reduce noise.
Commissioning steps: Power on via the 3500/91 190782-01 and confirm all channel LEDs illuminate. Use 170180-01-00 software to configure sensor types, measurement ranges, and alarm thresholds (e.g., “Motor bearing: 85°C warning”). Calibrate using a precision temperature calibrator, verifying accuracy at 0°C and 100°C. Test communication with the 3500/53 133388-01 by confirming temperature data appears in the controller’s interface, and validate 联动 with the 3500/65 145988-02 by triggering a test alarm.
Maintenance suggestions: Inspect quarterly, checking terminal blocks for corrosion and tightness—clean with isopropyl alcohol if needed. Verify calibration annually using a NIST-traceable standard, adjusting via software if drift exceeds ±0.5°C. Test surge protection semi-annually using a transient generator to ensure 2kV immunity. Unlike the 3500/65 145988-02, no relay contact testing is required, simplifying upkeep.
