Digital Junction Box-DJ04-2 With Modbus

Digital Junction Box-DJ04-2 With Modbus

Digital junction box with RS485 output +modbus

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.

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