Field Instrument Surge Protective Devices

Communication Lightning Protection Module

Communication Lightning Protection Module

Standard BNC coaxial interface is used for lightning protection of SD coaxial video surveillance system

PHL-S series SPD is mainly used to protect the field devices such as transmitters, switches, frequency signals, communication devices, TC, RTD, and I/O, DCS, PLC etc. in control room, which are connected by two-wire and three-wire systems, from damage because of lightning surge impulse voltage or operating overvoltage.

Product overview

The PHL-S series SPD is a device designed specifically to protect field equipment such as transmitters, switches, frequency signals, communication equipment, TC, RTD, etc. It can be applied to I/O, DCS, PLC and other equipment in the control room, which are usually connected using two wire and three wire systems. Therefore, effective protection is needed to prevent the impact of lightning impulse voltage or operation over-voltage.
