Three-wire and four-wire measuring bridges
Under the protection of the 3 or 4 wire system come the
following signals:
• PT100, measuring bridges, DMS sensors, measuring
bridges,
• Pluggable arrester, for non-interrupting and impedance
neutral plugging in/pulling out
• Can be tested with the V-TEST testing device
• Space-saving design for 4 binary signals
• Version with floating-earth PE connection used to avoid
interference currents that result from differences in
voltage potential
• Can be used in compliance with the IEC 62305 and IEC
61643-22 (D1, C1, C2 and C3) installation standards
• 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
