2. Product Features

• High Safety: Certified to SIL 3/ASIL D, with internal channel isolation to prevent fault propagation.
• Modular Design: Adopts standard DIN rail, enabling flexible combination inside the cabinet.
• Multiple Communication Methods: Built-in safety Ethernet and RS-485, supporting networking with other HIMA safety modules (such as F8627X) to achieve distributed safety control.
• Hardwired Logic: Basic functions (e.g., reset mode) are set via jumpers or DIP switches, no additional software programming required.
• Easy Maintenance: Screw terminal wiring and modular structure allow quick replacement and fault location.
• Strong Compatibility: Can work with other HIMA series (F-Series, Z-Series) as well as third-party PLC and SCADA systems.

3. Structure and Composition

• Body: Metal housing, conforming to 35 mm DIN rail specifications.
• Power Sub-modules: F7126 (5 V DC power supply), F7130A/F7131 (power monitoring).
• Communication Sub-modules: Ethernet card (F8627X) and RS-485 interfaces.
• Safety Relay Sub-module: 8-channel input / 8-channel output, with independent safety isolation for each channel.

• Automated Production Lines: Safety monitoring for automotive manufacturing, food processing, and logistics handling systems.
• Process Safety: Safety shutdown and fault isolation in industries such as chemical engineering, petroleum, and energy.
• System Integration: Combined with PLC, DCS, and SCADA to implement the overall Safety-Network.

5. Installation and Maintenance Points

Mechanical Installation

• Use standard 35 mm DIN rails and fix the module to the cabinet sidewall or rail frame.
• Ensure the module is placed horizontally to avoid contact issues caused by vibration.

Electrical Connection

• Use screw terminals for wiring; first confirm the power voltage (24 V DC) and wiring sequence.
• When connecting Ethernet and RS-485, follow HIMA’s recommended wiring specifications and ensure proper grounding of the shielding layer.

Configuration and Debugging

• Set the reset mode (manual/automatic) and input/output polarity via jumpers or DIP switches.
• After power-on, check the power indicator light to confirm the 5 V DC power supply is normal.
• Use external safety controllers (PLC, DCS) to simulate signals such as emergency stop and door interlock, and verify that the output is safely disconnected.

Daily Maintenance

• Regularly check the tightness of terminals to prevent misoperation caused by looseness.
• Perform a functional self-test every six months to confirm normal Ethernet and RS-485 communication.
• If module abnormalities are found, replace the corresponding sub-module or the entire unit in accordance with the HIMA maintenance manual.
