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 M12 ports.

The measuring amplifier has eight digital inputs and outputs.

On the backside SubD25 socket, strain gauge full-bridges and half-bridges 120 Ohm up to 1

kOhm as well as PT1000 temperature sensors and 1000 Ohm single grid strain gages or

voltages 0 ... 5V can be connected.

The front-end M12 socket is configured by default for strain gauge full-bridge connections

and for voltage inputs 0 ... 5V and 0 ... 10V.

Altering Straingage input to the voltage input

Opening the device

1.Remove both screw covers from the input side and remove the fastening screws from the
front cover.

2.The two hexagonal bolts on the 37-pin D-Sub port must be loosened using a socket
spanner (5 mm).

3.The printed circuit board is pulled out on the side of the 25-pin D-Sub port.

Wiring diagram for position sensors

The measuring amplifier GSV-4USB must be configured by the manufacturer separately
when using it with potentiometric position sensors (linear potentiometers or draw wire
displacement sensors) for the M12 version.
The position sensor’s wiper is connected to the measuring amplifier’s “Aux” input (M12) or
“UE“ (SubD37). The position sensor supplies via the sensor supply +Us and -Us.

5-pin port 37-pin D-SUB port

The potentiometric position sensor is supplied with 2.5 V.
The “Aux” input or UE records voltages of 0...5 V.
