Diagnostics messages
I/O error yes, if the segment voltage U<sub>S</sub> is not present
Overvoltage category
II (IEC 60664-1, EN 60664-1)
Pollution degree
2 (IEC 60664-1, EN 60664-1)
Maximum power dissipation for nominal condition
2 W (from HW 07)
3 W (up to HW 06)
Protective circuit
Protection against polarity reversal (segment supply/main supply); Parallel diodes for protection against polarity reversal; in the event of an error the high current flowing through the diodes causes the fuse connected upstream to blow.
Short-circuit protection of the analog supply; electronic
Short-circuit protection of the communications power; electronic
