M-LB-(Ex-)2000-System – Surge Protection Barriers
Product Specifications
2.3
Working Voltage
To ensure the best possible protection level, 2 different voltage versions are available.
•
Rated voltage U = 24 V DC, maximum continuous operating voltage U
The typical area of application for these surge protection barriers are 24 V signal loops,
such as 4 mA ... 20 mA, digital inputs or digital outputs.
•
Rated voltage U = 1 V DC, maximum continuous operating voltage U
These surge protection barriers are optimized for applications with a small voltage
increase in the mV range, such as resistance thermometers, thermocouples
or strain gauge bridges.
