Description
BENTLY 3500/60 133819-01 Module Full Technical Profile
This is the non-isolated internal-termination I/O variant of the Bently Nevada 3500/60 temperature monitoring module, purpose-built for the 3500 series machinery protection system, to deliver high-precision multi-channel temperature monitoring for critical industrial rotating equipment and process points.
Core Product & Technical Introduction
- Basic Identification: Part No. 133819-01, belonging to the 3500/60 temperature monitoring series, paired with the 163179-01 main monitor board to form a complete 6-channel temperature monitoring unit.
- Core Functionality: Supports 1 to 6 independent temperature input channels, compatible with both Resistance Temperature Detector (RTD) and Thermocouple (TC) sensor types, no recorder output is provided to focus purely on temperature signal conditioning and alarm logic processing.
- Signal Processing: The module conditions raw sensor signals, performs built-in linearization compensation for different sensor curves, and compares real-time readings against user-programmable alarm setpoints to trigger pre-configured warning or trip actions.
- Electrical Design: Adopts non-isolated I/O architecture with internal termination design, all field wiring terminates directly at the rear of the rack, eliminating the need for external junction boxes to reduce on-site wiring complexity.

Adaptive Quality Assurance & Test Protocol
This protocol is strictly implemented at the factory to ensure every 133819-01 module meets industrial-grade reliability standards before delivery:
- Adaptive Sensor Compatibility Test: Automatically identifies connected RTD (Pt100, Pt1000 etc.) and TC (K, J, T, E etc.) types, performs full-range input simulation for each of the 6 channels, verifies measurement accuracy stays within ±0.1% of full scale across the entire -200°C to +850°C operating range.
- Dynamic Load & Temperature Cycling Test: Subjects the module to 10 consecutive temperature cycles from -40°C to +85°C under full 6-channel load, continuously monitors signal stability to ensure no drift or data loss occurs under extreme temperature fluctuations.
- Vibration & Shock Compliance Test: Performs 10-2000Hz sinusoidal vibration test and 15g peak shock test according to IEC 60068-2-6 standard, verifies no loose internal components or signal interruption during mechanical vibration scenarios on industrial sites.
- Long-Term Burn-In Test: Runs 72-hour continuous full-load operation test with 24/7 data logging, automatically screens out modules with hidden early failure risks, ensures the mean time between failures (MTBF) exceeds 150,000 hours.
- Communication & Configuration Validation Test: Verifies full compatibility with the 3500 rack backplane communication protocol, confirms all alarm setpoint configuration, data transmission and fault diagnosis functions work 100% correctly.
Field Engineer Technical Instructions
- Pre-Installation Preparation: Confirm the 3500 rack is in a safe maintenance state, follow site lockout/tagout procedures, verify the module firmware version is V4.0 or later to ensure full compatibility with the existing rack system.
- Wiring Guidelines: Use shielded twisted-pair cables for all RTD/TC sensor wiring, separate temperature signal cables from AC power cables by at least 20cm, route them through independent cable trays to avoid electromagnetic interference; for TC wiring, use dedicated compensation wires matching the thermocouple type to eliminate cold junction compensation errors.
- Configuration & Calibration: After hardware installation, access the 3500 configuration software, select the exact sensor type, measurement range and alarm setpoints for each channel, perform a loop calibration test with a portable temperature signal simulator to confirm each channel reading matches the reference value within ±0.2°C.
- Routine On-Site Troubleshooting:
- For “open circuit” alarm: Check the continuity of the sensor wiring and internal termination terminals, confirm no broken wires or loose connections.
- For abnormal reading drift: Verify the compensation wire for TC is correctly connected, check if the RTD three-wire wiring resistance difference is within 5Ω, re-calibrate the channel if necessary.
- For module “OK” indicator off: Confirm the 24VDC rack power supply is within 17.5~26VDC range, re-seat the module to ensure full backplane connection.
- Hot-Swap Operation: The module supports hot-swap under normal system operation, after replacing the module, re-verify all channel configurations and perform a full loop test before restoring the monitoring function.
Compatible Peer & Series Models
As the non-isolated internal-termination I/O unit of the 3500 temperature monitoring family, it is fully compatible with the 3500 rack system, and its common associated models include:
- 163179-01: 3500/60 main temperature monitor board (without recorder outputs), paired with 133819-01 to form a complete 6-channel non-isolated temperature monitoring unit.
- 3500/61 series: 6-channel temperature monitoring module with independent recorder outputs for each channel, supporting direct connection to external recorders or data acquisition systems.
- 3500/60 Isolated I/O variant: TC isolated version of the temperature I/O module, designed for sites with high common-mode voltage interference to provide electrical isolation for each channel.
- 3500/60 External Termination variant: External terminal type temperature I/O module, allowing on-site wiring outside the rack cabinet for easier maintenance access.
