VSPC 4SL 24VDC EX:

• Binary signals (SL - Symmetrical Load) protection covers the following signals:
• switching signals between a common reference potential, such as 5 V, 24 V, and 60 V, and one without.
• Two-conductor systems typically use a shared reference potential for binary sensors, actuators, and indicators such as limit switches, buttons, position sensors, photoelectric barriers, contactors, solenoid valves, indicator lamps, and so on.
• For interruption-free and impedance-neutral plug-in and pull-out, use a pluggable arrester.
• able to be examined using the V-TEST testing apparatus.
• Version with floating-earth PE connection used to avoid interference currents caused by potential differences.
• For use in accordance with IEC 62305 and IEC61643-22 installation requirements (D1, C1, C2, and C3).
• A safe discharge of up to 20 kA (8/20 μs) and 2.5 kA (10/350 μs) to the PE is possible with an integrated PE foot.
• Voltage levels are colour-coded for easy identification on the panel.
• By using coding elements at various voltage levels, safety is provided.
