3 Product Description
The safety-related
F20
controller is a compact system in a metal enclosure with 8 digital
input and output (DIO) channels that can be configured as digital inputs or digital outputs.
Additionally, 4 pulsed outputs are available. For external communication, 2 Ethernet
connection and 2 fieldbus interfaces.
A fan located in the enclosure cover contantly cools down the device.
The controller is available in a model variant for SILworX and a model variant for ELOP II
Factory, see Chapter 3.2. All variants are described in this manual.
The device is suitable for mounting in Ex-zone 2, see Chapter 4.1.4.
The device has been certified by the TÜV for safety-related applications up to SIL 3
(IEC 61508, IEC 61511 and IEC 62061), Cat. 4 (EN 954-1) 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 8 safety-related, digital channels (DIO), which can be
individually configured as digital input or digital output. The state (HIGH, LOW) of each
input is signaled by an individual LED.
3.1.1 Safety-Related Digital Inputs
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.
