Description
BRT HX760 Load cell amplifier circuit module is a low-cost precision weight sensor signal conditioner designed for full-bridge load cell. It can convert the weight changes measured into the changes of resistance signal, and then converts the resistance signal into dc current or voltage signal output. Its output can be 0-10V voltage and 4-20mA current. Its differential input voltage is ±20mV, accuracy is 24bit. It operates in 9-24Vdc wide range power supply.

Terminal Definition
P1 Terminal block wring:
+24V: | Power supply + |
GND: | Power supply – |
V: | 0-10V output |
I: | 4-20mA output |
GND: | Power supply – |
Note:
Potentiometer RV1(OFFER) adjust output medium value.
Potentiometer RV2(ADJ) adjust output GAIN value (amplification times).
CH1 Terminal block wiring:
VDD: | Load cell power supply 5V + (red wire) |
I+: | Load cell in-phase input (green wire) |
I-: | Load cell anti-phase input (white wire) |
GND: | Load cell power supply -(black wire) |
*Note: please DO make sure the polarity connection is right, then power on! *It is designed for full bridge load cell/weight sensor, cannot be used with half bridge load cell.
HX760: output 4-20mA and 0-10V signal (0-10V output, power supply must be not lower than 15V.)
HX270: only outputs 4-20mA signal.
