DJ04 RS485 digital junction box weight transmitter for load cell


Connect 4 analog load cells
Send out digital output in signal of RS485
Most suitable for silo scale, batching scale


 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.
