3.1.2 Safety-Related Digital Outputs
The controller 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 F30 014 can be loaded with 0.5 A,
see Table 19.
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 17.
The extern
al wire of an output is not monitored, however, a detected short-circuit is signaled.

Figure 3: Connection of Actuators to Outputs
The redundant connection of two outputs must be decoupled with diodes.
WARNING
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.
