Control module for delta®
The new control module option extends the delta® range of pumps to become variable-dependent metering pumps.
This makes redundant the need for additional technically-complex and high-cost control circuits. These modules have an active 4-20 mA input for use with pH-20 mA or redox-20 mA transducers or chlorine sensors CLE-mA. The control uses PID control behaviour to adapt the pump precisely to the requirements of the process.
If a two-sided control is required, a second pump can be controlled via the optional pacing relay.
