Position:Product / Weighing Transmitter
Multichannel digital weighing junction box
Product model:ADS301

Channel : 4-8 Channel

Work voltage: 12-24vdc; Signal output: RS485/422

Application: platform scale, digital weighbridge, tank weighing, axle scale, digital weighing module

Product specifications

There are N load cell inlets and an N-channel A/D module in eachHirs-N (N-channel) digital weighing J-Box, which can process each channelsignal and output signals separately, or do the processing at one time andoutput signals in serial to the bus. In addition, angular difference adjustmentcan be done in the J-Box. Especially for muti-channel hopper/tank weighing,digital truck scale, industrial process weighing instruments.
