weighing scale load cell amplifier DJ04-2 RS485 digital junction box weighing transmitter with modbus for load cell

Digital junction box / weighing transmitter 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.
Digital junction box / weighing transmitter 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.
