Overview
The MK-BSQ-1CH is a digital weighing module that communicates over RS485 using standard Modbus RTU, supporting read and write function codes for straightforward system integration. It connects to Wheatstone-bridge strain-gauge sensors and converts their signal into digital weight data.
Key Features
- Standard Modbus RTU over RS485
- Works with Wheatstone strain-gauge sensors
- Supports 03, 06 and 16 function codes
- Sealed to Optocoupler isolation, power isolation, surge protection (not on basic version) for reliable operation in harsh environments
- Compact design for straightforward integration
Applications
Used to add digital readout and serial communication to load-cell-based industrial weighing systems.
