3. Product Features
- High Safety Performance: Compliant with SIL 3, equipped with complete self-diagnosis and fault isolation functions.
- Dual-Channel Redundancy: Local and remote logic solvers enable continuous operation without single-point failures.
- Modular Design: I/O modules can be flexibly inserted and removed on the same carrier, supporting hot swapping.
- Wide Compatibility: Natively compatible with the DeltaV SIS platform and can also connect to upper-level systems via standard Ethernet.
- Easy Maintenance: Status indicators, remote diagnostic information, and base design reduce maintenance costs.
- Environmental Adaptability: The industrial-grade housing is resistant to high temperatures, low temperatures, vibration, and impact, making it suitable for harsh on-site environments.
4. Structure and Composition
- Host (Logic Solver): The core processing unit with built-in CPU, memory, and storage.
- Redundant Communication Bus (SISnet): Enables synchronization between local and remote solvers.
- I/O Interface Board: Optional modules including discrete, analog, and HART modules.
- Power Module: Provides 24 V DC regulated power supply with overcurrent/overvoltage protection.
- Base/Rail Bracket: Ensures stable installation and facilitates wiring.
- Diagnostic/Indicator Lights: Display real-time operating status and fault information.
5. Application Fields
| Industry | Typical Safety Functions |
|---|---|
| Oil and Gas | Leak detection, Emergency Shutdown (ESD) |
| Chemical Industry | Overpressure protection, overtemperature protection, fire and gas detection |
| Electric Power | Substation safety interlocking, circuit break protection |
| Manufacturing | Mechanical protection, robot safety interlocking |
| Mining | Gas explosion protection, equipment anti-fall protection |
| Nuclear Energy | Radiation monitoring, emergency reactor shutdown |
| Rail Transit | Train collision prevention, signal safety interlocking |
6. Key Points for Installation and Maintenance
Installation
- Insert the SLS1508 into the odd-numbered slots (1, 3, 5, 7) of the 8-wide carrier; use 4 slots for redundant peer slots.
- Fix it using a base or rail to ensure vibration resistance and maintain heat dissipation channels.
- Connect the 24 V DC power supply, check the polarity, and then power on the device.
Wiring
- Select I/O modules as needed and wire using screw terminals or crimp terminals.
- Adopt the SISnet dual-channel bus to achieve synchronization between local and remote solvers.
Commissioning
- Download logic and configure parameters through the DeltaV SIS engineering software.
- Check the self-diagnosis report to confirm that the redundant links are normal.
Daily Maintenance
- Regularly check the indicator lights, power supply voltage, and wiring tightness.
- Use remote diagnostic functions to monitor module temperature and error codes.
- If module replacement is required, ensure the system is powered off or enters safe mode before hot swapping.
