Product Parameters

      1. Safety & Signal Characteristics
        • Safety Certification: SIL 2 (single module) / SIL 3 (redundant configuration) compliance per IEC 61508 Ed. 2; IEC 61511 compliant for process industry safety loops.
        • Input Channels: 8 x safety digital input channels (24V DC, PNP/NPN configurable); support for both dry contacts (e.g., emergency stop) and active sensors (e.g., proximity switches); input current: 2-10mA (normal state), <1mA (fault state).
        • Output Channels: 4 x safety digital output channels (24V DC, 2A per channel); forced-guided (FG) relays to prevent welded contacts; support for “on/off” safety actions (e.g., valve shutdown, motor trip).
        • Signal Validation: Built-in cross-channel monitoring (for redundant input signals), signal edge filtering (1-100ms adjustable), and wire-break detection (for input channels) to reject noise and false signals.
      2. Communication & Integration
        • Interface with LD800HSE Module: Supports ABB proprietary Safety over HSE (SoHSE) protocol for secure communication; integrates with LD800HSE’s redundant Ethernet links to ensure communication fault tolerance.
        • Backplane Compatibility: ABB AC 800M standard safety backplane connector; 32-bit data bus for high-speed safety signal exchange with safety controllers.
        • Diagnostic Data Transmission: Transmits real-time self-diagnostic data (e.g., channel fault status, power supply health, diagnostic coverage) to the LD800HSE module for upstream monitoring.
      3. Environmental Adaptability
        • Operating Temperature: -25℃ to +70℃ (suitable for safety cabinets near high-risk equipment like turbines or reactors).
        • Storage Temperature: -40℃ to +85℃ (meets extreme climate storage/transport requirements).
        • Humidity Resistance: 5% to 95% RH (non-condensing); circuit board with IPC-A-610 Class 3 conformal coating to resist moisture, oil, and chemical vapors.
        • EMI Immunity: Complies with IEC 61000-6-2 (ESD: 15kV air discharge, 8kV contact discharge) and IEC 61000-6-4 (RFI: 30MHz-1GHz, 20V/m field strength) to avoid interference from nearby VFDs or high-voltage equipment.
        • Vibration Resistance: IEC 60068-2-6 compliant; withstands 10-2000Hz sinusoidal vibration (15g acceleration, 10 minutes per axis) for stable operation in vibrating environments (e.g., power plant turbine halls).
      4. Reliability & Fault Tolerance
        • Mean Time to Failure (MTTFd): ≥ 1,000,000 hours (for input channels); ≥ 800,000 hours (for output channels) per IEC 61508 calculations.
        • Diagnostic Coverage (DC): ≥ 99% for critical fault modes (e.g., relay welds, wire breaks, power supply failures).
        • Fault Response Time: ≤ 100ms (from fault detection to safety action initiation, e.g., tripping an output channel).
        • Protection Functions: Overcurrent protection (output channels: 3A self-resetting fuse), overvoltage protection (power supply: 30V DC clamp), and undervoltage monitoring (24V DC input: <18V triggers fault alarm).
