Quick Detail

Description

The 136711-01 I/O Module is a six-channel signal interface designed for the Bently Nevada 3500 Machinery Protection System, supporting 1 to 6 RTD or thermocouple inputs in automated machinery protection applications. The 136711-01 I/O Module delivers 30 kHz bandwidth with 3% amplitude accuracy at 10 kHz and ±1% channel amplitude precision, ensuring accurate temperature and dynamic signal acquisition. Each channel features 10 MΩ input impedance and intrinsic safety parameters such as Uo 26.25 V and Io 88.39 mA for hazardous area installations. With temperature accuracy of ±1 °C at 25 °C and dedicated internal barrier circuitry, the 136711-01 I/O Module enables direct sensor connection in explosion-prone industrial automation systems. Integrated within a 3500 rack, the 136711-01 I/O Module supports precise monitoring of rotating equipment, turbines, compressors, and process-critical assets.

Applications

Monitor turbine bearing temperature in hazardous zones
The 136711-01 I/O Module connects RTD sensors installed on steam or gas turbine bearings, using its ±1 °C accuracy at 25 °C to detect abnormal heat rise and transmit data to the 3500 rack for alarm or trip logic execution.

Collect thermocouple signals from compressor casings
With support for up to six TC inputs and 30 kHz bandwidth, the 136711-01 I/O Module processes fast temperature fluctuations in centrifugal compressors, enabling automated shutdown when preset thresholds are exceeded.

Interface explosion-proof field sensors in oil and gas units
Using intrinsic safety outputs such as Uo 26.25 V and controlled Io values, the 136711-01 I/O Module allows direct wiring of field-mounted RTD or TC sensors in classified areas without external barriers.

Acquire multi-point temperature data in power generation systems
Six independent channels and 10 MΩ impedance allow the 136711-01 I/O Module to gather distributed temperature signals from boilers and auxiliary systems for centralized automation monitoring.

Specifications

Competitive Advantage

Enable direct hazardous area sensor wiring without external barriers
The 136711-01 I/O Module integrates internal barriers with defined Uo, Io, Co, and Lo parameters, reducing additional hardware and cabinet wiring steps.

Capture both thermal and dynamic signal components up to 30 kHz
Unlike temperature-only modules, the 136711-01 I/O Module provides wide bandwidth for detecting rapid signal variations in rotating machinery.

Maintain precise channel-level measurement at ±1 percent amplitude
Each channel in the 136711-01 I/O Module maintains ±1% amplitude accuracy, supporting accurate alarm setpoint configuration in automated protection systems.

Support flexible six-channel configuration within a single rack slot
The 136711-01 I/O Module processes up to six RTD or TC inputs in one module position, optimizing rack space for large-scale automation projects.
