Strain gauge signal converter WZ-SG
1 output optional: 0/4 mA to 20 mA, 0 V to 5/10 V, 1 digital output
- Scalable input for 4- or 6-wire strain gages
- Taring input and RS485 serial interface
- Fast and safe adjustment
- High fire safety due to the flame-retardant fiberglass-nylon housing
- 3-way isolation ( power supply / signal input / signal output ) up to 1500 VAC
In addition to converting the input signal into a scalable standard signal, the WZSG microprocessor-controlled transducer for strain gages also offers the option of a taring function or an output for outputting when a threshold value is reached. The output signal can be output as an analog current or voltage signal. The WZSG module also converts the input signals into a MODBUS RTU protocol. The data can be made available to corresponding evaluation devices via an RS485 interface. This means that the use of a controller is not necessary. The device is fully set up using the programming cable and simple software and is immediately ready for operation. The WZSG is simply snapped onto a top-hat rail for installation.
