English Description

The HIMA F3 DIO 20/8 024 is a remote Digital Input/Output module that provides a combination of digital inputs and outputs for safety-critical applications. It's part of HIMA's modular and compact safety systems, which are widely used in industries like oil and gas, chemical, power generation, and rail, where functional safety standards (e.g., IEC 61508, IEC 61131-2) are paramount.

Key features and characteristics of the F3 DIO 20/8 024 include:

• Manufacturer: HIMA Paul Hildebrandt GmbH + Co KG.

• Module Type: Digital Input/Output Module. The "DIO" signifies its dual capability.

• Input/Output Configuration:

• 20 Digital Inputs (DI): These inputs are used to receive signals from field devices such as sensors, switches, and emergency stops. They are typically designed for robust performance in industrial environments.

• 8 Digital Outputs (DO): These outputs are used to control actuators, relays, and other final control elements, often for safety-related actions like shutting down machinery or activating alarms.

• Voltage Level: The "024" in the part number commonly indicates a 24V DC (Direct Current) operating voltage for the inputs and outputs, which is standard in many industrial control systems.

• Safety Certification: As a HIMA product, this module is designed and certified for use in safety-instrumented systems (SIS), typically meeting Safety Integrity Level (SIL) requirements (e.g., SIL 3). This means it has a very low probability of failing dangerously.

• Line Monitoring: It includes line monitoring features for its digital outputs, which detect short circuits or wire breaks, enhancing the safety and reliability of the controlled circuits.

• Ex Zone Approval: It is often approved for use in Ex Zone 2 (potentially explosive atmospheres), making it suitable for hazardous area installations.

• Two Ethernet Switch Ports: The module typically includes two RJ-45 Ethernet ports (10/100 Mbit/s), allowing it to be integrated into network-based safety systems like SafeEthernet, and enabling remote I/O capabilities.

• High-Speed Counters: It includes two 100 kHz counters, providing high-speed counting capabilities for applications requiring precise measurement of pulses or frequencies.

• Robustness: Designed for harsh industrial conditions, it often features a wide operating temperature range (e.g., 0 to 60 °C, with some variants for -25 °C to 70 °C), vibration and shock resistance (e.g., according to IEC 61373 Class 1B), and IP20 protection.

• Programming: Configured and programmed using HIMA's SILworX software.

• Applications:

• Emergency Shutdown Systems (ESD)

• Fire and Gas (F&G) detection systems

• Burner Management Systems (BMS)

• Railway signaling and control

• Machine safety applications

• Any industrial process requiring high-integrity safety functions.

The F3 DIO 20/8 024 is a critical component for building reliable and highly available safety automation solutions, ensuring the protection of personnel, plant, and the environment.
