LY10 RS485 spd 10kA 4-20mA 12V 24V 48V signal surge protector is in series in front of protected equipment, mainly suits for communication line, remote signal, DDN, X. 25 data line, 10M ports line etc. Can Effectively absorb the energy impact generated by the surge, and introduce the energy into the ground through the grounding cable. 35mm standard DIN rail installation, save much space.

Features:
1. Plugable type, signal non-interrupted. When change module no need power off.
2.Protect one pair signal lines from lightning surge.
3.Din rail installation, save much space.
4.Several protection voltage selection, such as 12V 24V 36V 48V 110V.
5. Max discharge current 10kA(8/20) Type 2.

Installation and notes:
1.Surge protective device is in series in front of protected equipment, and before installation should power off, and forbidden to operate with power.
2.When installation should make sure to wire according to surge protective device indication In, Out and PE. Output side is connected to protected equipment. Can't reverse, otherwise when lightning it will damage surge protective device, and can not protect the equipment properly.
3.When installing the ground wire, disconnect the device to avoid damage to the device due to the introduction of strong currents such as electric welding from the ground wire.
4.Connect the ground wire of the surge protector and the metal shell of the device to the grounding bar.
It should test regularly during the surge protector using, if faults then should change or repair on time to ensure the safety of the protected equipment.
5.Non-professionals do not disassemble.
