3 Product Description
The safety-related F30 controller is a compact system in a metal housing with 20 digital inputs
and 8 digital outputs.
The controller is available in various model variants for SILworX and ELOP II Factory, see
Table 4.
The device is suitable for
mounting in Ex-zone 2, see Chapter 4.1.4.
The device is TÜV-certified
for safety-related applications up to SIL 3 (IEC 61508, IEC 61511
and IEC 62061), Cat. 4 and PL e (EN ISO 13849-1) and SIL 4 (EN 50126, EN 50128 and
EN 50129).
Further safety standards, application standards and test standards are specified in the
certificates 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 sig
nal 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.
