Wieland Electric‘s selos WK 6 TK block offers an optimal DIN rail block solution
for all types of measuring circuits of current, voltage or energy. All circuits
occurring during everyday practice can be implemented with the Instrument
isolating terminal and a few accessories.
Complete insulated selectable connecting links are available as standard,
as are insulated test sockets in all conventional signal colors. Two additional
jumpering facilities permit the installation of fixed cross connections (e.g.,
