2.3.3 Multi Control Unit (MCU)
The control unit has the following functions:
• Control of data transfer and processing the data from the measuring unit(s) connected
via RS485 interface
• Signal output via analog outputs (measured value) and relay outputs (device status)
• Signal input via analog and digital inputs
• Power supply for the connected measuring units via 24 V switching power pack with wide-
range input
• Communication with host control systems via optional modules
Plant and device parameters can be set easily and conveniently via a USB interface using a
laptop and the user-friendly SOPAS ET operating software. The parameters are stored
reliably even in the case of a power failure.
The control unit is usually installed in a steel plate housing.
