TRSS-485 control signal surge protection device
Model: TRSS-485
Color: white / red
Verification: CE
product description
The industrial control equipment is connected to the peripheral
line through the power line and the signal line, and the working
environment is relatively complicated, and is easily damaged by
lightning and the like, thereby causing damage to the equipment.
The function of the control signal lightning arrester is that when
the transmission line is subjected to induced lightning and other
transient overvoltage surges, the inrush current is discharged to
the earth through the protection branch of the surge protector, and
the output voltage is clamped to the device. Within the voltage
range, it can effectively prevent this from happening and ensure
the safety of the equipment.

Use attention
1. Connect the lightning protection device (SPD) between the line
and the device port to be protected. Connect the grounding port on
the SPD to the ground net with multiple strands of copper wire, and
ensure that the grounding resistance is not more than 4 ohms.
2. When installing, make sure that the '1' screw is installed in
place to make the line bond firmly. After installation, use a
multimeter to test whether each signal line is turned on. Do not
install the SPD with power, otherwise the SPD
3. The lightning protection device does not need long-term maintenance
when it is not required to be installed. It only needs routine
maintenance of the system; if there is a problem in signal
transmission during use, the signal transmission returns to normal
after replacing the surge protector. The surge protector is damaged
and needs to be repaired or replaced.
