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.

The controller is equipped with 2 independent counters with inputs that can be configured for 5 V or 24 V voltage level.
The required voltage level is determined by the user program with the Counter[0x].5/24V Mode system parameter.
Input A is the counter input, B is the count direction input and input Z (zero track) is used to reset.
Alternatively, all inputs are 3-bit Gray code inputs (in decoder operation) The following modes of operation can be implemented:
ƒ Counter function 1 (depending on the count direction input signal)
ƒ Counter function 2 (not depending on the count direction input signal)
ƒ Decoder operation with attached absolute rotary transducer Refer to Chapter 3.4.4 for the description of the counters configuration.
The safety-related counter has a 24-bit resolution, the maximum counter reading is 224 – 1 (= 16 777 215).
