Description
Core Product Summary
The HIMA F35 is a compact, safety-related programmable controller within the HIMatrix product family, engineered for critical industrial automation and railway applications. Certified for functional safety up to SIL 3 (IEC 61508) and PL e (EN ISO 13849-1), this standalone controller handles safety-critical interlocking, monitoring, and shutdown sequences in demanding process environments.
Housed in a rugged metal enclosure designed for standard DIN/panel mounting, the F35 integrates a versatile mix of onboard I/O: 24 digital inputs, 8 digital outputs, 8 analog inputs, and 2 high-speed counters. System communication and engineering configuration are driven by dual Ethernet ports supporting safeethernet protocols, alongside modular support for fieldbus options like PROFIBUS-DP. It operates on a standard 24 V DC industrial supply and is fully certified for deployment in Zone 2 hazardous areas.

Detailed Product Overview
The HIMA F35 functions as an intelligent safety controller capable of executing localized safety logic independently or as part of a distributed safety network. Its onboard 24 digital inputs sample field contact states and convert them internally into precise analog measurements before applying configurable software thresholds, allowing enhanced diagnostics over standard discrete inputs. The 8 analog input channels feature 12-bit resolution to monitor continuous safety parameters such as pressure, temperature, or level.
In addition to standard discrete processing, the unit includes two independent 24-bit counter inputs configurable for frequency counting, rotational speed tracking, or 3-bit Gray code absolute encoder decoding. Program execution and system configuration are managed via engineering environments such as SILworX or ELOP II Factory. The controller communicates safety-relevant data securely across Ethernet architectures using HIMA’s proprietary safeethernet protocol while isolating diagnostic and standard plant data streams.

Dimensions, Mounting & Connection Notes
- Physical Dimensions: Measures 257 mm wide x 114 mm high x 97 mm deep (excluding plug connectors and earthing hardware).
- Weight: Approximately 1.2 kg.
- Mounting Configuration: Compact metal housing engineered for panel or DIN rail mounting inside control cabinets, providing IP20 protection.
- Wiring Terminations: Uses removable plug-in screw or clamp terminal blocks for field signal wiring, keeping power, ground, and I/O segregated.
- Grounding and Shielding: Requires a low-impedance connection to the structural frame ground via the dedicated earthing screw to satisfy EMC noise immunity requirements.
