Product Description

Product About

SY232/422/485 Industrial control signal line surge arrestor is a surge protection device especially designed for RS232/422/485 signal circuit and ports. With internal over voltage and over current suppression model, and two levels connection circuit protection design, this kind of surge arrester can suppress surge voltage and current effectively. The product has applied the malfunction self-recovery design, thus providing thorough protection for the signal and the appliance, and ensure the transfer of signal and the operation of equipment.

According to the definition of the partition of lightning protection, this device can be installed on LPZ0A-2 or a higher interface, or it can be installed directly at the front-end of the protected equipment. It can be applied to protect the industrial control signal, such as the field bus, 0-20mA, control line, 4-20mA control line and other input and output interface.

Installation considerations

1，SPD shall be as close as possible to protect the equipment.
2，SPD grounding wire should be as short as possible and shall not exceed 1m.
3，When SPD fails, internal short circuit or circuit breaker status occurs, then the protective equipment is unable to carry out normal line pass. In that case, SPD should be promptly replaced.
4，SPD is a one-time security device, whose damage cannot be repaired.
