Programmable controller S-HD-KL

For discrete dosage and continuous delivery



The controller S-HD-KL is recommended for high requirements in control of discrete dosage and continuous delivery tasks in combination with Ex pumps mzr-2909 Ex / 4609 Ex / 7209 Ex and mzr-7259 Ex. 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. For the three digital inputs there is a screw terminal. Programs for dosage control can be saved in the memory.
