The S Series signal SPD is mainly used to protect field devices such as transmitters, switches, frequency signals, communication equipment, RTDs and thermocouples connected in two-wire or three-wire configurations, as well as control-room equipment such as safety barriers, I/O, DCS and PLC, from damage caused by lightning surge impulse voltages or switching overvoltages.
Addressing the lightning protection requirements of low-voltage industrial control signals, the S-Pro Series surge protective device was launched after the basic S Series, offering greater functionality and specialisation, including models for 5V/24V signal systems and 24VDC power supply systems.
