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.
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.
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 14.
The external wire of an output is not monitored, however, a detected short-circuit is
signaled.

Connection of Actuators to 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.
