DOK-CONTRL-S20*PSDI*8*-AP02-EN-P
IndraControl S20 Module With Safe Digital Inputs S20-PSDI-8/4
Safety characteristics according to EN ISO 13849-1
Achievable performance level
Diagnostic coverage (DC)
Mean time to dangerous failure (MTTFd)
Supply voltage U
The bus coupler or a feed-in terminal in the station supply the module with communications power U
For the technical data, please refer to the data sheet for the bus coupler or the feed-in terminal.

WARNING
The use of unsuitable power supplies can result in the loss of the safety function.
•
Use power supplies according to EN 50178/VDE 0160 (PELV).

Protection against polarity reversal
NOTICE
Parallel protection against polarity reversal is only implemented in the module for a limited period. The following measures
must be taken to prevent damage to the module:
•
Due to the maximum current capacity of 8 A, protect power supply U
•
Only use PELV power supply units with at least four times the nominal tripping current, as this is the only way to ensure
release times of less than 300 ms.
