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.

| |
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.
