PRODUCT DESCRIPTION

2.2.3
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.
