Surge protection devices (SPDs) for Modbus communication play a vital role in industrial automation and control systems . Key features include:
-
RS485 and RS232 Protection : Modbus generally uses RS485 and RS232 communication methods, so SPDs are required to protect the corresponding signal lines.
-
Lightning and overvoltage protection : Protects communication equipment from lightning and overvoltage occurring in the external environment.
-
Supports high-speed data transmission : Includes the ability to maintain signal quality to keep Modbus RTU and Modbus TCP/IP communications running smoothly.
-
Pluggable modules : Often supplied in pluggable module form for easy maintenance.
-
EMI/RFI Filtering : Minimizes electromagnetic interference (EMI) and radio frequency interference (RFI) to ensure stable data communications.
