Description
Core Product Summary
The HIMA F3 DIO 16/8 01 is a safety-related remote I/O module within the HIMatrix product family, designed for functional safety and process automation control architectures up to SIL 3 (IEC 61508) and PL e (EN ISO 13849-1). Housed in a compact metal enclosure, this module integrates 16 digital inputs, 8 two-pole digital outputs, and 2 pulsed outputs to process field signals and drive safety-critical actuators.
Engineered for distributed safety networks, the unit connects directly via two RJ-45 Ethernet ports supporting safeethernet communication for safety-related data exchange and standard protocols for configuration. It operates on a 24 V DC power supply and features line diagnosis functions capable of detecting open circuits and short circuits on the field outputs. The module is suitable for decentralized mounting in industrial automation control systems and Zone 2 hazardous areas.

Detailed Product Overview
The HIMA F3 DIO 16/8 01 functions as a remote safety I/O subsystem designed to expand safety controllers across distributed Ethernet networks. Signal processing is handled through its non-galvanically separated digital input channels and two-pole switching output channels. The 2-pole digital outputs utilize dual internal switches connected in series (one switching L+ and one switching L-), ensuring safe power disconnection to connected field devices upon fault detection.
For signal integrity and line monitoring, the module incorporates pulsed outputs that allow mechanical contacts to be monitored for cross-circuits and wiring breaks without needing external potential sources. Integrated line diagnosis actively monitors output circuits for short circuits (< 10 Ω) and open circuits (> 4 kΩ). Data transmission over the dual RJ-45 Ethernet switch uses HIMA’s safeethernet protocol, enabling safety-relevant data transfer between HIMatrix components while operating concurrently with standard network services.
