Serial Connection Problems in an Industrial Environment
|
| |
Serial
communication reliability can be adversely affected by hazardous
industrial environments. The wiring associated with serial
communication devices could be surrounded by power lines, motors, or
equipment that produces static electricity. If this is the case, the
serial devices could be damaged by sudden surge waves produced by
this type of equipment. In this situation, surge protection that
uses TVSS (Transient Voltage Surge Suppression) is the solution.
When two serial devices are directly connected, but separated by
a long distance, the unbalanced ground voltage could cause serious
damage. Unbalanced ground voltage between two serial ports forms a
"ground loop" that introduces a large current between the two pieces
of equipment. In fact, the current could be so large as to damage
the equipment beyond repair. In this situation, the solution is to
use Isolation Protection to completely isolate both communication
ports. |
What is Surge Protection?
|
| |
Surges are high
amplitude electrical pulses lasting only several millionths of a
second in duration. They can be caused by heavy-duty equipment,
power lines, short circuits, or large motors. A surge suppressor has
the ability to effectively absorb the high energy in an extremely
short period of time, preventing the connected devices from damage. |
What is Isolation Protection?
|
| |
The purpose of
electrical isolation is to electrically isolate two circuits that
need to communicate with each other. This is achieved by using a
photo coupler that transforms an electrical signal into light, and
then retransforms the light back into an electrical signal on the
other end. In this way, the two circuits are completely isolated
from each other electrically. |
Does Moxa support Surge Protection and Isolation Protection?
|
| |
Yes. As a
leading provider of serial communication products, our MOXA
engineers have introduced TVSS (Transient Voltage Surge Suppression)
and Optical Isolation technology into our multiport serial product
line. Our aim is to provide a secure and reliable yet cost effective
solution that improves the communication environment and protects
our clients' investment. Feel free to contact us for more
information about Moxa products that use TVSS and Optical Isolation
technology. |
