 RS485 RS232 420mA digital junction box weight transmitter for load cell

 

 the digital junction box is based on resistance strain sensor as signal source, It is composed of 24bits Σ-Δ type A/D conversion technology and the 8 bit single chip microcomputer etc.Large-scale integrated circuit. It is with high accuracy, high reliability. 

Main functions:

¨ panel keyboard settings, capacity calibration

¨ Has function to display weight setting. 

¨ Can point out failures, operational error.

¨ 4~20mA/RS485/RS232 output,Can set the corresponding weight value of 4mA and 20mA.
