VT485m Modbus RTU extension
Previous
Next
Description
Allows to monitor up to 32 Modbus RTU devices/meters/sensors. The maximum distance of a daisy chain is up to 1000 meters. Each metered value of a Modbus device is addressed individually using input registers and is shown by the system as virtual sensors. You can configure thresholds and icon representations for these elements.
A slot PCB board can be inserted inside the monitoring unit while the unit is in operation. Has an internal termination and by default, it is switched ON (if required can be turned off).
Models
VT485m:
Used for monitoring systems VT335t, VT825t, VT855t. Power connector is tilted 90 degrees.
VT485d:
Used for monitoring systems VT336t. Power connector is looking straight.
Use cases
The VT485m Modbus RTU monitoring extension has various use cases across multiple industries and applications:
- Industrial Automation: The extension can be used to monitor various industrial devices and meters, such as temperature sensors, flow meters, or energy meters. It allows for precise real-time monitoring and control of processes.
- Building Management Systems (BMS): In a BMS setup, the extension helps monitor HVAC systems, lighting, and energy consumption using Modbus-compatible devices, ensuring efficient energy management and operation.
- Data Centers: This extension can track critical environmental data such as temperature, humidity, or power usage across multiple Modbus-enabled devices within a data center, ensuring optimized conditions and early alerting in case of abnormalities.
- Energy Management: For monitoring solar inverters, battery management systems, or other power meters, this extension facilitates efficient data acquisition and allows operators to maintain optimal energy flow and usage levels.
- Remote Monitoring of Critical Infrastructure: The extension is useful in applications where remote sensors are deployed, such as in oil and gas pipelines, utility substations, or other infrastructure that requires remote monitoring and control.
