Product Description Ordering Key
DSB 51 X X S
DSB51XXS is a surge pro- tecting device that has been specifically designed for 2 and 4 wires communi- cation buses at 5V (eg. RS485, RS422 (with 2 devices) and Modbus RTU
), measuring, controlling and regulating devices used in industrial and resi- dential environments. It can also be used for pro- tecting from overvoltages
Type Selection
devices such as inverters, energy meters, interface protections (coupling devices), control and acquisitions systems in photovoltaic installations that are interconnected by means of serial communi- cation lines. The construc- tion is DIN rail mounting and the cartridge is replaceable.
