A1A-D25 Load Cell Amplifier

ANYLOAD A1A D25 strain gage amplifiers provide load cell and transducer signal conditioning.  The A1A series strain gage amplifiers are DC-powered amplifiers that can drive 1 load cell connected directly. They can also drive several load cells up to 4 x 350Ω load cells or 8 X 700Ω load cells through a junction box. Housed in an aluminum casting enclosure. The A1A-D25 digitizer module includes both RS232 and RS485 communication interfaces with ModBus protocol.

  • Small volume and enable to mount inside of load cell
  • One input port, can connect directly to 1 x 350 Ω load cell, or max 4 x 350 Ω (or higher resistance) load cells through a junction box
  • 24-bit A/D Converter, high speed processor
  • Internal digital filter and strong anti-interference ability
  • Contains ability for 9 point linear calibration
  • Applied to all kinds of strain gauge bridge-type load cell, such as, tension, compression, torque and so on.
