Description
This 4-channel measuring amplifier for sensors with strain gauges is equipped with a USB
interface. The voltage is supplied via the USB port at the back of the measuring amplifier.
The measuring amplifier can be delivered with an SUB-D37 connection or with 4x M 2 ports.
The measuring amplifier has eight digital inputs and outputs.
On the backside SubD25 socket, strain gauge full-bridges and half-bridges 20 Ohm up to
kOhm as well as PT 000 temperature sensors and 000 Ohm single grid strain gages or
voltages 0 ... 5V can be connected.
The front-end M 2 socket is configured by default for strain gauge full-bridge connections
and for voltage inputs 0 ... 5V and 0 ... 0V.
