HIMA Z7128/6217/C5/ITI (SIS) module
HIMA Z7128/6217/C5/ITI
HIMA Z7128/6217/C5/ITI is a Safety Instrumented System (SIS) module under the HIMA product series, specifically designed for high-risk industrial processes. It complies with the IEC 61508/61511 standards and holds SIL 3 certification. This model integrates control, communication, and power supply functions, adopting a modular structure that makes it suitable for scenarios requiring high reliability and redundant protection.
Main Specifications
- Model: Z7128/6217/C5/ITI
- Safety Level: SIL 3 (compliant with IEC 61508)
- Protection Level: IP20 (for DIN rail mounting)
- Power Supply: 24 V DC, supporting redundant power supply modules
- Communication Interfaces: Modbus RTU, RS‑232/RS‑485, and Ethernet (optional)
- I/O Capacity: Each I/O sub-rack can accommodate 16 I/O modules, supporting digital signals, analog signals, and safety-specific signals
- Operating Temperature: 0 °C ~ 55 °C (fanless heat dissipation)
Product Features
- High Reliability: Adopts a fanless heat dissipation design and a compact DIN rail structure to reduce the risk of mechanical failures.
- Modular Design: The central rack, communication modules, and power supply modules can be flexibly combined, facilitating expansion and maintenance.
- Multi-Protocol Compatibility: Supports multiple fieldbuses and Ethernet protocols, enabling easy integration with upper-level systems.
- Safety Certification: Complies with IEC 61508 and has obtained SIL 3 certification, making it suitable for safety control in hazardous environments.
- Easy Installation: Features standard DIN rail mounting; supporting installation brackets (such as the Z7128/6217/C5 bracket) simplify on-site layout.
Structure and Composition
- Central Unit: Serves as the core processor and the module for implementing safety functions.
- Communication Module: Provides multiple communication methods, including Modbus, RS‑485, and Ethernet.
- Power Supply Module: Supplies 24 V DC power and supports redundant power supply configurations.
- I/O Sub-rack: Each sub-rack can hold 16 I/O modules, compatible with digital, analog, and safety signals.
- Installation Bracket: A dedicated DIN rail bracket (Z7128/6217/C5) is used to fix the chassis, enhancing heat dissipation and anti-vibration performance.
Typical Application Fields
- Petrochemical, oil refining, and natural gas processing industries
- Power generation, iron and steel, cement, and automotive manufacturing industries
- Pharmaceutical and biotechnology industries
- Process Safety Systems (PES) and functional safety control
- Any industrial automation scenarios requiring high-reliability safety control
Installation and Maintenance Guidelines
- Installation: Fix the module on the DIN rail in accordance with the instruction manual to ensure the bracket is stable and avoid impact or vibration; check the correctness of power wiring and communication ports.
- Wiring: Follow the wiring specifications of IEC 61882/61511 standards, and use cables and connectors that meet safety level requirements.
- Commissioning: Perform a self-test before powering on for the first time to confirm that all module status lights are normal; use the configuration software provided by HIMA to conduct functional tests.
- Regular Inspection: Conduct on-site inspections every 6 ~ 12 months, focusing on checking the tightness of wiring, heat dissipation and ventilation, and the status of indicator lights.
- Troubleshooting: In case of a fault, first check the system log and fault code; if necessary, contact HIMA’s official after-sales service for on-site maintenance or module replacement.
