The unit has all the qualities a powerful process measurement transmitter should have today.
There are two free programmable relays available for limit values with hysteresis for min-, max- as well as for pump exchange action. One more error report relay and a scalable galvanically isolated 0/4 - 20 mA output can be used for control purposes and for measurement value evaluation.
