SLA2X is an unit suitable for the connection with capacitance and ultrasonic level transmitters. It displays the input analog variable and depending of model, it can provide 2 or 4 relays.
Each threshold can be programmed with different kinds of hysteresis. Two analog exit 0÷10V and 4÷20mA, and RS232 or MODBUS serial port are available, depending of the model. It is specially used to be directly connected to TC22, TC26 e TC30 capacitance level transmitters, or to power METER ultrasonic transmitters (2-wire). A special function allows a remote selfcalibration.
It can memorize empty-situation by acting on a push-button and the level-condition (from 20 to 100%) by acting on another one.
The level measurement can be converted into volumes or weights, and an optional linearization system can convert to engineering units a level not commensurated with the volume.
