3.1.2 Safety-Related Digital Outputs
The remote I/O is equipped with 8 digital outputs. The state (HIGH, LOW) of each output is
signaled by an individual LED (HIGH, LOW).
At the maximum ambient temperature, the outputs 1...3 and 5...7 can be loaded with 0.5 A
each; and outputs 4 and 8 can be loaded with 1 A or with 2 A at an ambient temperature of up
to 50 °C.
Within a temperature range of 60…70 °C, all outputs of the F3 DIO 20/8 023 and
F3 DIO 20/8 024 can be loaded with 0.5 A, see Table 15 and Table 16.
If an overload occurs, one or all digital outputs are switched off. If the overload is removed, the
outputs are switched on again automatically, see Table 13.
The external wire of an output is not monitored, however, a detected short-circuit is signaled.

Figure 3: Connection of Actuators to Digital Outputs
The redundant connection of two outputs must be decoupled with diodes.
CAUTION
For connecting a load to a 1-pole switching output, use the corresponding L- ground of
the respective channel group (2-pole connection) to ensure that the internal protective
circuit can function.
Inductive loads may be connected with no free-wheeling diode on the actuator. However, HIMA
strongly recommends connecting a protective diode directly to the actuator.
