Example of chlorine control with feedforward control
1
Connection of the inductive proximity switch INS of CCA250 to the digital input of the DIO module
2
Connection of the signal from a flowmeter to the digital input of the DIO module
3
Activation of a (pulse) dosing pump via the digital output of the DIO module
A
Dosing pump
Utilize the advantage of the effectively wear-free control with binary outputs versus a control
system with relay. With pulse frequency modulation (PFM), it is possible to achieve virtually
continuous dosing using a dosing pump with higher input frequency.
1. Connect the INS proximity switch of the CCA250 assembly to a digital input of the DIO
module (e.g. slot 6, port 1).
