RTU 560 Hardware
� RTU hardware are base on European standard card format 100 x 160 mm.
� RTU 560 principle is built by one or two main subrackcontaining the communication and processing unit with serial or ethernet interfaces and I/O subracks with the I/O board.
� 2 types of RTU configurations:� RTU 560A
� RTU 560C
� The I/O subrack connected to CMU’s with serial RS 485 interface A or B.
