3 Product Description
The safety-related F30 03 controller is a compact system in a metal housing with 20 digital
inputs and 8 digital outputs.
The configuration is carried out with the programming tool SILworX, see Chapter
4.3.
The device is suitable for sequence of events recording (SOE), see Chapter
4.2. The
device supports multitasking and reload. For more details, refer to the System Manual for
Compact Systems (HI 800 141 E).
i
A licence is required to use the events recording, the multitasking and the reload features.
The device has been certified by the TÜV for safety-related applications up to SIL 3
(IEC 61508, IEC 61511 and IEC 62061) and PL e (EN ISO 13849-1). Further safety
standards, application standards and test standards are specified in the certificate available
on the HIMA website.
3.1 Safety Function
The controller is equipped with safety-related digital inputs and outputs.
3.1.1 Safety-Related Digital Inputs
The controller is equipped with 20 digital inputs. The state (HIGH, LOW) of each input is
signaled by an individual LED.
Mechanical contacts without own power supply or signal power source can be connected to
the inputs.
Potential-free mechanical contacts without own power supply are fed via an internal short-
circuit-proof 24 V power source (LS+). Each of them supply a group of 4 mechanical
contacts.
Figure 1 shows how the connection is performed.
With signal voltage sources, the corresponding ground must be connected to the input (L-),
see
Figure 1.

Figure 1: Connections to Safety-Related Digital Inputs
For the external wiring and the connection of sensors, apply the de-energized-to-trip
principle. Thus, if a fault occurs, the input signals adopt a de-energized, safe state (low
level).
If an external wire is not monitored, an open-circuit is considered as safe low level.
