Bently Nevada 125720-01 is an input/output (I/O) expansion module in the 3500 series monitoring system, primarily used to expand the system's signal acquisition and control capabilities. It supports connections with external sensors, actuators, and other devices, enhancing the monitoring and control functions of the 3500 system in complex industrial environments. The following is the relevant content from its user manual:

Product Overview

As an expansion component of the 3500 system, this module is designed to make up for the insufficient number of I/O interfaces in the basic system. It can access various types of analog and digital signals, enabling the monitoring of auxiliary equipment parameters (such as temperature, pressure, liquid level, etc.) and supporting the output of control signals to drive external alarm devices or actuators. It is widely used in the auxiliary system monitoring of large rotating machinery such as steam turbines, compressors, and generators, and is an important part of building a comprehensive equipment condition monitoring network.

Technical Parameters

Power Supply: 24V DC input, typical power consumption ≤ 3.5W.
Signal Types and Channels:

Analog Input: 8 channels, supporting 4-20mA current signals or 0-10V voltage signals, with 12-bit resolution and ±0.1% FS accuracy.
Digital Input: 4 channels, compatible with dry contact or wet contact signals (input voltage 24V DC), response time ≤ 10ms.
Digital Output: 4 channels, relay output (normally open contacts) with a contact capacity of 250V AC/5A or 30V DC/5A.

Signal Processing:

Analog inputs support programmable filtering (low-pass filtering, with cutoff frequencies configurable as 1Hz, 10Hz, or 100Hz) to reduce high-frequency noise interference.
Digital inputs support edge triggering (rising/falling edge) or level triggering modes, with configurable debounce time (0-100ms).

Communication Interface: Communicates with the Rack Interface Module (RIM) via the 3500 system backplane, with a maximum data update rate of 100ms per cycle.

Operating Environment:

Operating temperature: -40°C to 70°C;
Storage temperature: -50°C to 85°C;
Relative humidity: 5% to 95% (non-condensing);
Vibration resistance: 5g (10Hz-2000Hz);
Shock resistance: 25g (11ms half-sine wave).

Mechanical Specifications: Approximately 100mm × 150mm × 35mm (half-height module), weight about 0.3kg.

Functional Features

Flexible Expansion: By adding this module, the number of I/O channels in the system can be expanded as needed, meeting the multi-parameter monitoring requirements of different devices without replacing core monitoring modules.
Mixed Signal Support: Simultaneously supports analog and digital signal input/output, compatible with common sensor and actuator types in industrial fields, improving system versatility.
Linked Control: Can be linked with vibration, speed, and other monitoring modules in the 3500 system. When key parameters exceed limits, it triggers external alarms (such as sound and light alarms) or protection actions (such as shutdown) through digital output, achieving closed-loop control.
Status Diagnosis: Equipped with channel-level fault diagnosis functions, capable of detecting analog input disconnections, short circuits, abnormal digital input signals, etc., and uploading fault information to the RIM module for quick problem location.
Modular Design: Supports hot-swapping, allowing installation or replacement while the system is powered on without affecting the operation of other modules, reducing maintenance downtime.
