The Dry Contact Extension Module expands the capacity of compatible IoT controllers by adding up to 10 additional dry contact inputs. This allows the connected controller or dosing system to operate and monitor up to 10 additional suction lances with level switches.
Connected via RS485, the module supports flexible system expansion and enables additional dosing lines to be monitored without replacing the existing controller.
