Omrdon Technology 
OMS-CS24-2S rail twisted pair signal lightning protection for PLC industrial control, measurement and control system RS485, 4-20mA signal lightning protection
Product Description:
OMRDON (OMRDON) Twisted Pair Signal Lightning Protector (SPD, Surge Protector) is designed according to IEC and GB standards, mainly used for industrial control system data control signals, communication lines, telemetry signals, remote control signals, fire control, fire fighting, fire fighting, fire fighting, fire fighting, broadcasting, and other signals, such as signaling lines of the Lightning Electromagnetic Pulse (LEMP) Surge Protection, applied in the lightning protection area of the 1 -2 and 2-3 areas.
The product is encapsulated in a DIN-rail housing with a built-in high quality high-speed over-voltage protection device, which provides efficient protection and defense against lightning high-voltage pulses induced on the signal line.
Functional Features::
- High speed response (10-12 nanoseconds), low loss (≤0.3db).
- Internal two-stage series linkage protection, low residual voltage, long service life.
- With triple protection function of over-current, over-voltage and clamping, fast response speed.
- When a lightning surge intrudes, there is no need to suspend the power-using equipment, and it does not affect the normal operation of normal equipment.
- Novel appearance design, small size, easy to install.
- High transmission rates and a wide range of usage frequencies.
- International certification RoHS, CE, FCC.
typical application::
- 4-20m A signaling equipment system
- RS485 communication line
- Fire control circuits

Installation Precautions
1. The output ports of this series-type lightning protector are connected to the protected equipment.
2、Positive and negative lines should not be connected to the reverse or wrong, remember not to work with electricity.
3, lightning protector installed in the front of the protected equipment the closer the better.
4. The equipment needs to be inspected regularly, and the product must be replaced immediately after deterioration.
