VSPC 1CL 24VDC R
Pricing available on request
VSPC 1CL 24VDC R:
- Analog signal/current loop (CL) protection encompasses the following signals:
- Signals from current loops (analogue readings of sensors over long distances): 4-20 mA, 0-20 mA, etc.
- three-, four-, and two-wire systems without a single reference potential.
- For example, level indication signals from voltage sensors (0; 10 V, PT 100, etc.) and temperature measurement.
- Pluggable arrester featuring pull-out and plug-in that is interruption-free and impedance-neutral.
- able to be examined using the V-TEST testing apparatus.
- A version with a floating-earth PE connection was used to avoid potential discrepancies.
- Suitable for usage in accordance with IEC 62305 installation standard (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.
