2 PRODUCT DESCRIPTION
2.2.4 MCU control unit
Control unit MCU has the following functions:
● Control of the data traffic and processing of the sender/receiver unit data connected via
the RS485 interface
● Signal output via analog output (measured value) and relay outputs (device status)
● Signal input via analog and digital inputs
● Power supply for the connected measuring unit via 24 V switch-mode power supply with
wide range input
● Communication with higher level control systems via optional modules
Equipment and device parameters can be set easily and conveniently via a USB interface
using a PC and a user-friendly operating program. The parameters are stored reliably even
in the case of a power failure.
Control unit MCU has a sheet steel enclosure as standard.
