Description:

Suitable for intelligent control systems, 

twisted pair data signal over-voltage protection. 

It from over-voltage sensing, 

and over-voltage damage caused by electrostatic discharge.

Installation and construction of 

one, mine are connected in series, "output" are connected equipment to be protected, to be installed in the front of the device to be protected. 

2, to regularly check mine, please change occurs when the deterioration of the product, in order to avoid your unnecessary losses. 

3, the SPD shall be grounded, and the ground must be well grounded straight line shall not exceed 4 ohms resistance. Remember not live working, construction should be checked after the closing run mine without exception. 

4, should be in front of mine need to install short-circuiting device, to avoid a short circuit caused the fire after lightning deterioration. 

5, the mine should be installed in a waterproof case, to avoid mine water to make lightning function failure.

Control signal 485 SPD: protection for sensitive control signal transmission, widely used in computer communication systems, anti-monitoring control systems, access control intercom system, automatic control systems, security systems and other data transmission control signal lines lightning surge protection. Typically used in computer RS485.
