ABB SYN5302-0277 Scale Variable System

SYN5302-0277 is a PLC-based RTU realization scheme for medium and low voltage distribution network automation, which can fully meet the special requirements of medium and low voltage distribution network automation. It has the following features and advantages: simple hardware structure, completely maintenance-free; the scale can be large or small, just connect the PLC expansion module together, you can realize the remote control points, telecommunication points, telemetry points increase; resistance to harsh environments; high reliability; programming to achieve a variety of functions, free of hardware debugging; low cost.

The RTU of SYN5302-0277 needs to accept the instruction from the monitoring center and upload the information of the distribution network and switchgear, so the communication function is the main consideration for selecting PLC. Since the operation type and number of operation points of each switch room and switchgear cabinet often differ greatly, whether PLC has modular structure and configuration capability, and whether it can flexibly and economically form a variable scale system of input points, output points, measurement points (A/D) and regulation points (D/A) is another major consideration in selecting PLC models.
