- Converts the input signals into a 0/4 - 20 mA, 0/2 - 10 V or 0/1 - 5 V signal
- Supply via 10 - 40 VDC, 19 - 28 VAC
- Simple commissioning possible via DIP switch or USB interface
The WZ109REG21 universal signal converter converts current/voltage signals, signals from temperature sensors as well as resistance signals and potentiometer signals into a standard current or voltage signal. The output signal is linearly proportional to the input. The additional input/output can be used to output an alarm value or to operate several WZ109REG21s in multiplex mode on a PLC. The device is fully set via DIP switches, software on the PC or via the TEST3 calibration device and is immediately ready for operation. For mounting, the WZ109REG21 is simply snapped onto a DIN rail.
