Bürkert signal input board for MultiCell 8619 transmitter/controller

The modular multichannel MultiCell 8619 is designed with standard functions and extension modules, to customise the transmitter/controller to specific application needs and connected sensors. A new extension module has been released, as a signal input board that can be used for direct connection of two additional digital-input flow sensors and two additional analog-input measurement devices.

The signal input board features two 4-20 mA signal inputs for any type of transmitter with a suitable signal output, such as measuring pressure, level or water chemistry parameters including turbidity, oxygen, free chlorine, ozone, etc. These analog inputs can be locally altered to 0-5 or 0-10 V inputs. By using the analog inputs as external setpoints, further functionality is achieved.

The board is equipped with two digital NPN and PNP transistor inputs for the connection of transmitters with frequency output, such as flow transmitters. Alternatively, the digital inputs can be used as contact inputs to trigger selected functions of the 8619.

The transmitter is delivered precommissioned, with the user parameterising inputs and selecting scaling and units as required. All standard units for pressure, temperature, flow rate and many other types of measurements are available. In addition, a free text for a physical unit of a measurement value, such as ‘Brom ppm’, can be defined.

The transmitter/controller can be equipped with up to six I/O boards in a free mix of board types, making it suitable for complex tasks. This is extended by a maximum of six parallel and independent operations, freely selectable from a valid functions list. Often-used functions are built for simple selection and use.

Optional software packages allow additional adaptation to individual applications.
