Supply voltage U
M
(actuators)
Note:
Module damage due to polarity reversal
Polarity reversal places a burden on the electronics and, despite protection against
polarity reversal, can damage the module. Therefore, polarity reversal must be
prevented.
Undervoltage detection
Yes, at 17 V, approximately
Diagnostic indicators
Green U
M
LED
(see "Local diagnostic and status indicators" on page 12)
External fuse protection
8 A slow-blow, maximum
Note:
Module damaged when overloaded
The power supply unit must be able to supply four times (400%) the nominal current of
the external fuse.
Safe digital outputs OUT0 to OUT3
Number
4 two-channel or 8 single-channel (positive switching)
Supply
From supply voltage U
M
Maximum output current per output 2 A
Maximum output current for all
outputs (total current)
6 A (observe derating and maximum output current for
each group)
Maximum output current for each
group (total current)
Group 1 (OUT0_K1, OUT1_K1,
OUT2_K1, OUT3_K1)
3 A
Group 2 (OUT0_K2, OUT1_K2,
OUT2_K2, OUT3_K2)
3 A
Maximum output voltage in the low
state
< 5 V
WARNING
Loss of safety function
At this voltage, the load must not switch to or remain in the ON state. Please take this
into consideration when selecting the actuator.
Maximum leakage current in the low
state
2 mA
