For discrete dosage and continuous delivery

The controller S-BL is recommended for high requirements in control of discrete and continuous delivery tasks in combination with a mzr-pump with special brushless motor. The 16-bit microcontroller allows speed and position control for highly accurate dosage. The compact design on a PCB offers flexible installation. Process control link can be established via a  RS-232 interface. Motor speed or flow rate can be set either by an analog input (0-10 V) or a potentiometer mounted on the PCB. Programs for dosage can be saved in the memory.
