Bently Nevada 136711-01 Temperature Monitoring I/O Module for 3500 Series – Rear I/O for 3500/60 Temperature Monitor

The Bently Nevada 136711-01 is the rear I/O module used with the 3500/60 Temperature Monitor. From my experience, it’s the piece that quietly does the heavy lifting—terminating RTD and thermocouple wiring cleanly, providing cold-junction handling for TCs, and ensuring the temperature channels reach the monitor reliably through the 3500 backplane. If you’re maintaining a 3500 rack, this is a straightforward, drop-in I/O replacement that typically keeps your outage time to a minimum.

Key Features

• Purpose-built for 3500/60 Temperature Monitor – Ensures correct pinout and backplane connectivity with the 3500 rack.
• Multi-sensor support – Typically accepts RTDs (Pt100, 2/3/4‑wire) and common thermocouple types (J, K, T, E, N, R, S, B) via the monitor configuration.
• Clean field wiring – Plug-in terminal blocks help speed up installation and maintenance during turnarounds.
• Stable temperature measurements – Designed to work with the 3500/60’s cold-junction and linearization capabilities for consistent readings.
• Backplane powered – No external power wiring; the module draws from the 3500 rack.
• Drop-in replacement – Fits the standard 3500 rear I/O slot; no cabinet rework in most cases.

Technical Specifications

Application Fields

You’ll typically see the 136711-01 in continuous machinery protection systems where temperature is a primary indicator: compressor and turbine bearing metal temps, gearbox oil and casing temps, motor and generator stator winding RTDs, and high-value pump sets. It’s common across oil & gas, petrochemical plants, power generation (GT/ST), steel mills, pulp & paper, and large water treatment facilities—anywhere a 3500 rack is watching critical rotating assets.

Advantages & Value

• Reliability in harsh environments – Built for industrial cabinets with vibration and temperature swings.
• Exact fit, faster turnaround – Minimizes wiring changes and helps cut downtime during maintenance windows.
• System-level compatibility – Plays nicely with the rest of the 3500 ecosystem, which, in many cases, simplifies spares and configuration management.
• Practical cost control – A targeted replacement of the I/O module rather than full monitor swaps can materially reduce spend.
• Pre-shipment testing – From my experience, verified functionality before dispatch saves hours in the field.

A maintenance supervisor in a Gulf Coast refinery told us they swapped a 136711-01 during a night shift and had their bearing RTDs reading correctly within an hour—no re-termination hassle, no rework on the door layout.

Installation & Maintenance

• Panel/Cabinet – Install in a 3500 rack mounted within a ventilated cabinet; keep ambient within 0–65 °C and away from high EMI sources.
• Wiring practices – Use shielded twisted pairs for RTDs; for thermocouples, use proper TC-grade extension wire and avoid routing alongside power cables.
• Grounding – Maintain single-point grounding for shields; avoid ground loops that can skew low-level temperature signals.
• ESD & handling – Observe ESD precautions when inserting/removing the I/O module and terminal blocks.
• Routine checks – Verify terminal tightness during outages; spot-check calibration against a known reference if temperature drift is suspected.
• Firmware/config – Temperature linearization and alarm settings live in the 3500/60/TDI configuration; review after any channel or sensor changes.

Quality & Certifications

• CE compliant; UL/cUL for industrial control equipment (IEC/UL 61010-1) – typical for 3500-series modules
• RoHS compliant (2011/65/EU and amendments), depending on production lot
• Manufactured under ISO 9001 quality systems
• Seller warranty: 365 days

Related/Supporting Components

Note: Specific sensor type support and channel configurations are determined by the paired 3500/60 monitor and its configuration. If you’re replacing an I/O module in a mixed-RTD/TC cabinet, share a photo of the existing terminal labeling and we can help double-check wiring continuity and channel mapping before you power back up.
