Features:

  • Flexible External Termination for Simplified Field Wiring
  • Broad Sensor Compatibility Across 16 Channels
  • Rugged Industrial Reliability with Global Certifications
The Bently Nevada 172115-01 centralizes all RTD and isolated tip thermocouple sensor connections outside the 3500 rack, eliminating the need for internal chassis wiring. This external termination design significantly reduces installation complexity, accelerates commissioning, and allows maintenance personnel to access and troubleshoot field wiring without powering down the monitoring system or opening the main rack.

Supporting both 3-wire and 4-wire RTDs as well as isolated tip thermocouples, the Bently Nevada 172115-01 provides unmatched flexibility for multi-point temperature monitoring. Each of its 16 channels can be independently configured via 3500 rack configuration software, enabling a single termination block to handle diverse sensor types across turbines, compressors, bearings, and other rotating machinery assets.

Engineered for harsh environments, the Bently Nevada 172115-01 operates reliably from -30°C to +65°C and maintains high input impedance (>1 MΩ) to preserve signal integrity. When installed as part of a certified 3500/65 system, it supports hazardous area approvals including CSA/NRTL/C, ATEX (Ex nA nC ic IIC T4 Gc), and Class I Division 2, making it suitable for oil refineries, power plants, and other explosive or high-risk industrial settings.

The 172115-01 Bently Nevada external termination block may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Bently Nevada 172115-01 serves as the external termination interface for the 3500/65 temperature monitoring module, supporting up to 16 channels of RTD (3-wire or 4-wire) and isolated tip thermocouple inputs. Designed for demanding industrial applications, this termination block allows maintenance teams to centralize field sensor wiring, simplifying troubleshooting and reducing system downtime. Its robust construction ensures reliable operation in harsh environments, including high-vibration and extreme-temperature conditions commonly found in turbine and compressor installations.

Engineered specifically for external termination I/O modules (172109-01), the Bently Nevada 172115-01 eliminates the need for internal rack wiring, offering greater flexibility during system commissioning and retrofits. The Euro-style connectors provide secure and repeatable terminations, minimizing the risk of loose connections or signal drift over time. This plug-and-play approach significantly reduces installation errors and accelerates project timelines.

Whether you are upgrading an existing Bently Nevada 3500 monitoring system or building a new protection solution, the Bently Nevada 172115-01 delivers dependable performance. Its compatibility with standard 3500 rack configurations and adherence to global safety and environmental standards make it the preferred choice for reliability engineers and plant maintenance professionals worldwide.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the main purpose of the Bently Nevada 172115-01 in a monitoring system?
The Bently Nevada 172115-01 is used as an external termination block for the 3500/65 16-channel temperature monitor. Its job is to bring all field sensor wiring (RTD and thermocouple) to a single, accessible location outside the main rack, making installation and maintenance easier without disturbing the monitor chassis.
In what real-world applications would I use the Bently Nevada 172115-01?
You would use it in critical rotating machinery applications such as gas turbines, steam turbines, compressors, generators, and large pumps. It is common in power plants, oil refineries, LNG facilities, steel mills, and paper machines where reliable temperature monitoring of bearings, windings, or process temperatures is essential for asset protection.
Can I use the Bently Nevada 172115-01 with any 3500/65 I/O module?
No. The Bently Nevada 172115-01 is only compatible with the external termination I/O module (172109-01). It cannot be used with the internal termination I/O module (172103-01). Mixing them will result in an
What problems does the Bently Nevada 172115-01 solve during installation?
It solves the problem of cramped rack wiring and difficult troubleshooting. Without an external termination block, all sensor wires must be routed directly into the rack, making wiring messy, increasing installation time, and forcing maintenance personnel to open the rack for any wiring check. The Bently Nevada 172115-01 moves all terminations outside, allowing fast access and cleaner rack organization.
How does the Bently Nevada 172115-01 affect system diagnostics and troubleshooting?
By centralizing all field wiring at an external panel, the Bently Nevada 172115-01 allows technicians to quickly isolate sensor issues from monitor issues. They can measure signals directly at the terminal block without removing the I/O module or powering down the system, significantly reducing mean time to repair (MTTR).
