3500/42 176449-02
l Product introduction
- The BENTLY NEVADA 3500/42 176449-02is an advanced transducer signal conditioner module, designed to build on the capabilities of the 3500/40 176449-01 by offering expanded channel capacity, enhanced signal processing, and direct thermocouple compatibility. It serves as a high-performance bridge between a broader range of industrial sensors and the 3500 series machinery protection system, specializing in conditioning, filtering, and converting raw analog signals into standardized outputs for seamless integration with downstream modules.
- This module extends the monitoring capabilities of 3500 series racks by supporting not only ±10V DC and 4-20mA signals (like the 3500/40 176449-01) but also direct thermocouple inputs—eliminating the need for external transmitters. With 8 input and 8 output channels, it can handle more sensors simultaneously, making it ideal for complex machinery with multiple auxiliary parameters to monitor. Its Ethernet port enables remote configuration and data streaming, enhancing flexibility in large-scale installations. By converting signals to the 4-20mA standard, it integrates smoothly with alarm systems like the 3500/60 163179-01relay module, ensuring that critical sensor data triggers appropriate actions.
l Core advantages and technical highlights
- Expanded sensor compatibility: Building on the 3500/40 176449-01’s capabilities, the 3500/42 176449-02adds direct support for 7 thermocouple types (J, K, T, E, R, S, B), allowing direct connection of high-temperature sensors without external transmitters. This reduces complexity and potential points of failure in applications like furnace monitoring or exhaust gas temperature measurement. It also retains compatibility with ±10V DC and 4-20mA signals, supporting pressure transducers, flow meters, and level sensors.
- Superior signal processing: Equipped with 24-bit ADC resolution (compared to the 3500/40 176449-01’s 16-bit) and a wider filtering range (0.1Hz to 10kHz), the module delivers higher measurement accuracy and more precise noise reduction. For example, it can filter ultra-low-frequency drift from a level sensor or high-frequency noise from a high-speed pressure transducer, ensuring that signals sent to the 3500/60 163179-01relay module are clean and reliable.
- Enhanced isolation and safety: With 5kVrms channel-to-channel and channel-to-backplane isolation (double the 3500/40 176449-01’s 2.5kVrms), the module provides superior protection against ground loops, voltage transients, and electrical interference. This is critical in high-voltage environments like power plants or steel mills, where electrical noise can corrupt signals and compromise system safety.
- Remote configuration and monitoring: The integrated Ethernet port allows remote configuration via 170190-01Esoftware, eliminating the need for on-site access during setup or adjustments. It also supports real-time data streaming to cloud platforms or SCADA systems via the 3500/93 communication gateway, enhancing visibility in distributed facilities. This feature is particularly valuable for large installations where multiple 3500/42 176449-02 modules are deployed across different locations.
l Typical application scenarios
- In combined-cycle power plants, the 3500/42 176449-02replaces multiple 3500/40 176449-01 modules by handling 8 sensors simultaneously. It directly connects K-type thermocouples on gas turbine combustion chambers (eliminating transmitters), conditions 4-20mA signals from steam pressure transducers, and processes ±10V outputs from vibration accelerometers. The conditioned signals are sent to the 3500/60 163179-01 relay module, which triggers cooling system adjustments or shutdowns based on temperature and pressure thresholds. Operators monitor real-time data via the 3500/50 133388-02 display, while the Ethernet port streams data to a cloud platform for long-term trend analysis.
- Within steel mill rolling lines, the module monitors multiple parameters of hot rolling mills: it uses R-type thermocouples to measure roll temperature, 4-20mA pressure transducers to track hydraulic pressure, and flow meters to monitor coolant flow. Its high isolation (5kVrms) protects against electrical noise from nearby motors, ensuring accurate measurements. If roll temperature exceeds safe limits, the 3500/60 163179-01activates a relay to reduce furnace heat, preventing roll damage. The 3500/42 176449-02’s Ethernet port allows remote technicians to adjust filtering settings via 170190-01E software, optimizing signal quality without interrupting production.
- In chemical processing plants, the module integrates with hazardous area sensors (via intrinsic safety barriers) to monitor reactor temperature (S-type thermocouples), pressure (4-20mA transducers), and level (±10V sensors). It conditions these signals and sends them to both the 3500/50 133388-02display (for local monitoring) and the 3500/60 163179-01 relay module (for safety actions). If pressure spikes, the relay module triggers an emergency vent, while the Ethernet port alerts the plant’s DCS via the 3500/93 This multi-layered approach ensures rapid response to critical conditions.

l Installation, commissioning and maintenance instructions
- Installation preparation: Install the 3500/42 176449-02in an available slot in the 3500 rack. Power off the rack and use an anti-static wrist strap. Ensure the module is positioned to accommodate wiring from 8 sensors (e.g., thermocouples, pressure transducers) and an Ethernet cable. Required tools include a torque wrench (0.5-0.7Nm), wire strippers, and a screwdriver for terminal blocks.
- Installation steps: Align the module with rack guides and insert until the backplane connector engages. Secure with mounting screws. Connect sensors to input channels: use thermocouple-grade wire for thermocouple inputs and shielded cable (e.g., 149992-01) for other signals. Connect output channels to downstream devices like the 3500/60 163179-01relay module. Connect the Ethernet port to the plant network for remote access. Label all connections clearly.
- Commissioning: Power on the rack and connect to the module via 170190-01Esoftware (either locally via backplane or remotely via Ethernet). For each channel, configure input type (thermocouple type, ±10V, or 4-20mA), scaling, and filtering. Calibrate thermocouple channels using a reference thermometer and precision heat source; use a signal generator for other inputs. Test signal flow by applying known inputs and verifying outputs on the 3500/50 133388-02 display and 3500/60 163179-01 relay activation.
- Maintenance suggestions: Perform monthly visual inspections to check for loose connections, terminal corrosion, or damaged cables. Clean terminals with a dry cloth and tighten connections as needed. Quarterly, verify calibration using precision instruments: for thermocouples, use a dry-block calibrator; for other inputs, use a signal generator. Test isolation with a megohmmeter to ensure it remains above 5kVrms. Update firmware via Ethernet using 170190-01Esoftware to access new features. Backup configurations to the software and a secure server.
