TRSS-485 control signal surge protection device
Model: TRSS-485
Color: white / red
Verification: CE
product description
TRSS-485 signal lightning arrester is mainly used for lightning
(overvoltage) protection of equipment entering the equipment along
the low voltage control signal line. It is widely used in financial
systems, telecommunication systems, transportation systems, stone
chemical control systems, such as various data. Transmission line,
monitoring control line, instrumentation signal line, etc.
The product's compact design saves space in the cabinet and is
suitable for a wide range of process control requirements. The
internal reliable hybrid protection circuit, combined with the
optional “loop fuse protection” function, can be used for various
process control systems. A surge protection solution is available.
Product Features
1. Wide range of use, strong versatility
2. Energy saving, environmental protection, easy installation,
suitable for various standard interface types
3. Ultra-thin design, easy to install, automatic grounding via DIN
rail
4. Small VSWR and wide operating frequency range

Product working principle
TRSS-485 signal surge protector is connected in series with the
front end of the protected device. 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 is output.
The voltage is clamped to the voltage range allowed by the device,
thus ensuring the safety of the operating equipment.
Use attention
1. This product is connected in series.
2. Please select the same type of interface as the protected device
interface.
3. The IN of the lightning arrester is the input, the OUT is the
output, the input terminal is connected to the external line, and
the output end is connected to the input end of the protected
device.
4. The PE wire of the lightning protection device must be reliably
connected with the ground wire of the lightning protection system.
The connection wire is required to be short, thick and straight.
