• Compliance Standards: Complies with EMC standard EN 61000 – 6 – 2/4; meets ATEX, IECEx and CSA standards for Class I, Zone 2 hazardous areas
• Front-Panel Indicators: Equipped with OK, TX/RX and bypass status LED indicators

Function Features

• Dual Pairing Programming: The monitoring channels can be programmed in pairs and can perform up to two monitoring functions at the same time. For example, the first two channels can monitor radial vibration while the latter two channels monitor thrust position, enhancing monitoring flexibility.
• Customizable Alarm Settings: Users can set alarm setpoints for each active static measurement value and danger setpoints for any two of these values. The setpoints can be adjusted between 0 – 100% of the full scale, adapting to the monitoring needs of different types of machinery.
• Intuitive Status Monitoring: Front-panel LED indicators clearly show the module’s operating status. The OK light indicates normal operation, the TX/RX light reflects communication status, and the bypass light shows whether it is in bypass mode, enabling maintenance personnel to quickly identify operational issues.
• Protected Output Interface: The buffered transducer outputs come with short-circuit protection. This design prevents module damage caused by short circuits in external circuits, enhancing the module’s operational reliability and service life in complex industrial environments.
• Flexible Parameter Monitoring: Through configuration software, each channel can be programmed to monitor multiple parameters such as radial vibration, thrust position, eccentricity, differential expansion, acceleration and velocity, covering all key health indicators of rotating machinery.

Function Features
