8620 Multifunction Controller
Brand: Burkert Fluid Control Systems
The mxCONTROL multifunction controller, is a microprocessor controller designed to automate the control of process variables within a water treatment system (e.g. boiler, cooling tower or Reverse Osmosis system). Sophisticated electronics and state of the art control algorithms ensure that optimum process control is maintained at all times, with minimal operator intervention.
The controller is capable of processing numerous combinations of Analog and digital in and outputs. Combined with an easy to read large graphic display backlight in three languages, EN, DE, FR. Other languages on demand. The controller is highly software based. It can easily be configured/parameterized using a PC tool and SD card or USB interface.
Alternatively, the optional Ethernet interface can be used to configure and to parameterize the controller. Local manual parameterizing of the controller can also be achieved via the five soft-touch keys.
Features- Data and event logging
- One controller hardware with dozens of configuration possibilities quickly downloaded via SD card (supplied) or via USB interface
- Ethernet or modem communication with email or call event notification and numerous input/output control signals
