Product Description

The safety-related F35 controller is a compact system located in a metal enclosure with 24

digital inputs, 8 digital outputs, 2 counters and 8 analog inputs.

The controller is available in 3 model variants for SILworX and 3 model variants 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 4.1.5.

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.

Safety Function

The controller is equipped with safety-related digital inputs and outputs, safety-related

counters and safety-related analog inputs.

Safety-Related Digital Inputs

The controller is equipped with 24 digital inputs. The state (HIGH, LOW) of each input is

signaled by an individual LED.

The input signals are captured as analog measurements and provided to the program as a

range of INT values from 0…3000 (0…30 V). Configurable thresholds are used to generate

BOOL values, see Table 26

The default setting is:

Low level:  < 7 V

High level:  > 13 V

The thresholds are set using system parameters taking the safety-related accuracy into

account, see Table 43 and Table 44.
