1.2.3.4 Technical data
24 V supply
The module and the safe output must be supplied with 24 V from safely separated power
supply units. If electrical isolation is required, separate voltage supply lines must be used.
Detailed features of the 24−V supply
Terminal Specification [Unit] min. typ. max.
+, − Supply voltage of the module via a safely separated
power supply unit (SELV/PELV) [V] 19,2 24 30
Input current [mA] 350
24O, GO Supply voltage of the safe output via a safely
separated power supply unit (SELV/PELV) [V] 18 24 30
Input current [mA] 1100
If the voltage of the SELV/PELV power supply unit can exceed 30 V in the event of an error,
provide for an external fuse (
¶ 1.1.8).
Inputs and output
The inputs and the output are isolated and designed for a low−voltage supply of 24 V DC.
The digital inputs are protected against polarity reversal.
