Analogue signal / CL (current loop) protection includes
the following signals:
• Signals from current loops (analogue measurements of
transmitters over long distances) 4-20 mA, 0-20 mA,
etc.
• Two-wire, three-wire and four-wire, without a common
reference potential
• for example: fill-level measurement signals from voltage
transmitters (analogue measurements of transmitters
over short distances) 0-10 V, PT 100 etc.; for example:
temperature measurements
• Pluggable arrester, with no-interrupt and impedance-
neutral plug-in and pull-out
• Can be tested with the V-TEST testing device
• Space-saving design for 2 analogue signals
• Version with floating-earth PE connection used to avoid
differences in voltage potential
• Can be used in compliance with the IEC 62305 (D1,
C1, C2 and C3) installation standard
• Integrated PE foot, safely discharges up to 20 kA (8/20
μs) and 2.5 kA (10/350 μs) to PE
• Quick identification in the electrical cabinet with
coloured labelling of the voltage levels
• Coding element for the different voltage levels provides
safety
