User manual IC220SDL953 - September 2011
GFK-2731
Permissible interruption time
10 ms;
Within this time, the output voltage for the safe outputs fails as the outputs
are not internally buffered.
Surge protection
Yes (in the bus coupler/power terminal)
Protection against polarity reversal
Yes (in the bus coupler/power terminal)
Undervoltage detection
Yes, at 17 V, approximately
Diagnostic indicators
Green U
M
LED
(see "Local diagnostic and status indicators" on page 2-6)
External fuse protection
Maximum 8 A, slow-blow
Supply voltage U
M
(actuators) (continued)
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.
NOTE: Module damage in the event of overload
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
Maximum leakage current in the low state
2 mA
Minimum withstand voltage of the connected loads
> 5 V
Maximum inductive load
1 H
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.
