Your versatile partner in measurement and control technologyWith

its modular design, the multi-channel controller proves to be an adaptable and extremely competent companion for various measurement and control tasks. The modularity of the multi-channel controller makes it possible to record a wide range of measurement parameters such as chlorine, pH value, redox value or even quadruple pH value measurements in any conceivable combination,

and the outputs are also freely selectable. Dosing pumps can be controlled via optocouplers or relays, as well as actuators via relays or a 20 mA output.

The colour display with a very high resolution shows a user-friendly user interface. The user-friendliness is rounded off by simple touch operation and multilingual, intuitive menu navigation.

Free digital outputs can be configured as required. Regardless of whether they are to switch in the event of low sample water, measured value overflow, measured value underflow or other possible alarm triggers: There are no limits to the configuration.

You can use the four analogue outputs (0/4 - 20 mA) or the network capability to forward measured values to a web browser or a remote control station. An adjustable time interval can be used, for example, to automatically remind you to replace sensors due to wear and tear, and

data such as measured values, settings and alarm messages can be easily saved to a USB stick via a USB interface.

Core functions of the multi-channel controller at a glance:

• Graphic display of the setpoint deviation
• Up to four setpoint sets can be configured and loaded via digital input or timer control
• Service entries and sensor changes can be saved
• Limit value control (can be used as DIN contact for partial load operation in accordance with DIN 19643)
• 1 - 9 potential-free relay outputs
• Web server and Modbus protocol via Ethernet
• Trend display
• Large colour touch display
