Data
CU240B-2 With RS485 interface for the
following protocols:
USS
•
Modbus RTU
•
CU240B-2 DP With PROFIBUS interface
You have two options for the Control Unit power supply:
Supply from the Power Module
•
External supply via terminals 31 and 32 with 20.4 ... 28.8 VDC.
•
Use a power supply with protective extra low voltage (PELV according to EN 61800-5-1),
Class 2.
The 0 V of the power supply must be connected to the PE of the plant/system through a
low-ohmic connection.
The power supply is electrically isolated from the control terminals.
