ATLINE series

Protection for the digital and analogical equipment connected to these lines (computers, PLCs, load cells etc.). Wide variety of protectors for different working voltages.
Connects up to 2 pairs of lines that are very small in size. Both common and differential protection recommended for this type of line.
With removable modules for replacement in the event of a breakdown or fault. The power supply is not interrupted when replacing the module.
It has a radiofrequency receptor in order to carry out maintenance using only an emitter kit.
Earthing system is introduced through a metal sheet opposite to the fixing on the DIN rail.
Discharge takes place in an internal encapsulated element with no external flash.
Low residual voltage for all operating voltages.
Quick response.
Mechanical connection of conductors using screws, in order to absorb a higher amount of overvoltage.
In normal conditions, it remains inactive without affecting line operation or producing any leakages.
ATLINE series protectors have been tested in official, independent laboratories obtaining their characteristics according to applicable standards.

ATLINE24 is a version for DC lines with Un = 24VDC. C2 Test (2kA/4kV). Up = 70 V

Installation

Protectors should preferably be installed as close to the equipment as possible.
One communication cable or data line may contain several wires. Each ATLINE can protect up to four of these wires in series.
The recommended installation procedure is the following:

1 - Cut the data cable.
2 - Insert the cable ends into the connectors. Carefully check that the input and output connections are correctly placed.
3 - Connect the DIN rail to the earth terminal, since the overvoltage will be diverted to this element.

Safety & Maintenance

Earthing system is introduced through a metal sheet opposite to the fixing on the DIN rail.
Connection to earth is a must. Earthing in the whole installation must be bonded either directly or by a spark gap and resistance should be lower than 10 Ω.
