HIMA F3430 Digital Output Module
HIMA F3430
1. Overview
- Product Positioning: A safety-related digital output module that complies with functional safety standards such as IEC 61508 and IEC 61511, and has obtained SIL 3 (EN 61508) certification.
- Applicable Systems: Designed for safety PLCs/safety controllers of the HIMA PES (Process-oriented Safety) platform. It can form a complete safety control system together with HIMA F-series input modules, CPUs, communication modules, etc.
- Model Meaning: “F” stands for safety I/O, “3″ represents the 3rd-generation technology platform, “4″ indicates 4-fold outputs, and “30″ is the product series code.

| Protection Class | IP 20 (for indoor installation) |
| Communication Interface | Dual redundant RAM interface (DPR) for synchronization between two CPUs |
| Compatible Modules | Used with F-series input modules, CPUs, and communication modules (PROFIBUS, Ethernet/IP, etc.) |
3. Product Features
- High Safety Redundancy: Adopts a 1oo2D (dual-microprocessor) + dual 1oo2D (2oo4D) structure. The failure of any single component will not affect the overall function, achieving no single-point failure.
- Rapid Fault Recovery: The dual RAM interface (DPR) ensures real-time synchronization between the two CPUs, with a fault recovery time of < 10 ms.
- Modular Design: Features pluggable cards that support hot swapping, facilitating on-site replacement and expansion.
- Diagnostic Function: Equipped with self-test, channel status monitoring, and short-circuit/open-circuit detection, supporting on-site diagnosis and remote monitoring.
- Strong Compatibility: Complies with IEC 61508/IEC 61511 and can be used in environments with various fieldbuses (PROFIBUS, PROFINET, Ethernet/IP, Modbus).
- Environmental Adaptability: With a wide temperature range, resistance to humidity and electromagnetic interference, it is suitable for harsh industrial sites such as petrochemical, metallurgy, and pharmaceutical industries.
4. Structure and Composition
- CPU Module (Central Control Unit): Two 1oo2D microprocessor cards, providing redundant computing and safety logic.
- Output Card (F3430): 4-channel relay/transistor outputs, each with independent safety isolation (AK 1) and short-circuit protection.
- Power Module: Supplies 24 V DC power and is equipped with over-voltage and under-voltage protection.
- Communication Backplane: Dual redundant RAM interface (DPR) enables high-speed synchronization between the CPU and I/O cards.
- Chassis/Installation Frame: Standard 19-inch rack or DIN rail-mounted chassis, facilitating on-site arrangement.
5. Typical Application Fields
