Weidmuller Transclinic 8i+ Bedienungsanleitung Seite 38

While you read this user guide and become familiar with the product we would like to
highlight why more than 3 GW worldwide are being monitored with Transclinic:
• The Transclinic is a rugged, industrial measurement equipment. Watch out when
comparing PV monitoring systems as not all withstand the same temperature range
under full load, the surges due to indirect lightning strikes, the dusty and/or humid
atmospheres...
• The Transclinic is meant to measure, among other variables, string current and
system voltage under the tough electromagnetic interferences typically found in
PV plants. That is why it has passed successfully EMC tests under industrial-grade
immunity requirements.
• The Transclinic measures current by means of redundant, high stability current-
sensing resistors (also known as shunts). Shunts offer a very linear and predictable
response not subject to hysteresis offsets, overload offsets and other defects found
in other current sensing technologies.
• The Transclinic contains 9 high-voltage insulation barriers meant to handle safely
the toughest surges while guaranteeing auxiliary circuits free of ground-loops.
• The Transclinic is certified for safety and EMC in an independent accredited
laboratory in the European Union, using the latest available IEC/EN standards.
• The Transclinic fulfills the latest RS–485 and Modbus industry standards and can be
easily integrated into a Scada or a PLC/datalogger because Weidmüller discloses all
the register map information to you in this user guide.
• The Transclinic lets you measure up to three crystalline strings combined into one
input thanks to its extended current measurement range.
