Four-Channel Multi-Parameter Monitoring

As a 4-channel isolated I/O module, it supports simultaneous access to various industrial sensors, including accelerometers, proximity probes, and speed sensors. It enables multi-parameter measurement such as vibration, proximity, and rotational speed.
For example, during steam turbine operation, the module can:

Capture real-time vibration amplitude,

Monitor shaft rotational speed,

Detect bearing position and component status through proximity sensing,
thus providing comprehensive, multi-dimensional data for equipment diagnostics and troubleshooting.

Intrinsic Safety Protection for Hazardous Environments

A key feature of this module is its built-in isolation barrier, which provides an intrinsic safety interface for connected sensors. It integrates:

Over-voltage protection

Short-circuit protection

Reverse-polarity protection

This intrinsically safe design allows the module to operate reliably in hazardous locations such as oil and gas fields or chemical plants, where there is a risk of fire or explosion. Unlike external isolation barriers, the integrated design avoids performance degradation and helps maintain overall system responsiveness and accuracy.

Flexible Compatibility and Easy System Upgrades

The module can seamlessly integrate with the Bentley 3500 series mechanical protection system. It supports smooth communication with corresponding racks and management software, and is compatible with multiple industrial communication protocols such as DeviceNet and Modbus TCP, enabling flexible deployment, centralized management, and convenient system upgrades.
