Overview
The MK-BSQ-4CH is a weighing signal module that adapts load-cell outputs to a standard Modbus RTU interface, supporting the common read and write function codes used on plant networks. It is compatible with all Wheatstone-bridge strain-gauge sensors, so existing scale designs gain digital integration without changes to the mechanical build.
Key Features
- Standard Modbus RTU protocol
- Compatible with all strain-gauge load cells
- Sealed to Optocoupler isolation, power isolation, surge protection (not on basic version) for reliable operation in harsh environments
- Compact design for straightforward integration
Applications
Provides Modbus RTU integration of strain-gauge weighing signals into industrial control and monitoring systems.
