Communication SPD (for communication/signal) SG series
Showden Co., Ltd.
About This Product
■Summary
This is a plug-in SPD that protects FA equipment and instrumentation equipment from lightning surges that invade signal lines and communication lines. Impulse durability corresponds to JIS categories D1 and C2. This is a standard type with high cost performance that meets the public construction work standard specifications supervised by the Ministry of Land, Infrastructure, Transport and Tourism, Minister's Secretariat Office Construction Department.
■Uses a plug-in structure
Plug-in structure improves maintainability. It also has a mechanism to prevent the plug from coming off, improving plug-in reliability. The SPD plug can be inserted and removed without interruption.
■Compatible with various lines
Compatible with all lines including current signal 4-20mA, temperature measurement signal, RS485, 422 line, relay control line, PV measurement data line, etc.
■Compatible with various standards
Impulse durability complies with JIS categories D1 and C2, making it an environmentally friendly RoHS compliant product. In addition, it meets the public building construction standard specifications supervised by the Ministry of Land, Infrastructure, Transport and Tourism, Minister's Secretariat, Construction and Maintenance Department.
