ABB LD800HSE 3BDH000320R0101 Foundation Fieldbus Linking Device

Input/Output Types:

Response Time: Input filtering time adjustable from 0.1ms to 100ms, output response ≤1ms, suitable for high-speed logic control scenarios.

Isolation Characteristics: Electrical isolation between channels (isolation voltage ≥500V AC), isolation between input/output and power supply, with strong anti-interference capability.

Bus Protocol: Communicates with AC 800M controllers via backplane bus, supports Modbus RTU/TCP expansion (requires matching communication modules), and is compatible with ABB S800 I/O systems.

Electrical Interface: Plug-in design with Phoenix terminal blocks, supporting hot-swapping, clear terminal identification for convenient on-site wiring.

Power Supply: 24VDC±20%, redundant power input design (supporting dual-power backup), typical power consumption ≤15W, reverse polarity protection.

Environmental Adaptability: Operating temperature -20℃~+70℃, humidity 5%~95% (non-condensing), IP20 protection level, meeting industrial site requirements for vibration resistance and dust prevention.

Petrochemical Industry: Valve switch status acquisition and control in Emergency Shutdown Systems (ESD), cooperating with SIL-certified systems to achieve safety interlocking.

Power Industry: Circuit breaker status monitoring in substations, relay protection signal output, supporting redundant configuration to enhance system reliability.

Metallurgical Production Lines: Rolling mill start-stop control, conveyor operation status monitoring, reducing downtime risks through redundant I/O modules.

Rail Transit: Switch position detection and signal light control in signaling systems, meeting the high-reliability requirements of the railway industry.

Construction Machinery: Solenoid valve control for shield machine hydraulic systems, sensor switching signal acquisition, adapted to harsh working conditions.

Food and Beverage Production Lines: Valve switching for filling equipment, sensor counting signal processing, conforming to hygienic design standards.

35mm DIN rail mounting, supports vertical/horizontal installation, requiring ≥50mm heat dissipation space; when in redundant configuration, needs to be installed in pairs and interconnected via backplane bus.

Indicators: Power (dual-power status), Run (operation), Error (fault), Channel Status (channel abnormality indication), locating problems via LED flashing frequency (e.g., corresponding light remains on in case of channel short circuit).

Software Diagnosis: Read module status codes (e.g., 2001 indicating output overload) via ABB Control Builder software, supporting remote fault log recording and export.

Compatible with AC 800M controller firmware V4.3 and above, needs to be used with ABB S800 I/O system or High-Availability (HSE) framework, requiring redundant parameter configuration during hardware configuration.

Digital Input: External contact signal → terminal block → signal filtering circuit → optoelectronic isolation → level conversion → microprocessor cache → transmission to controller via backplane bus.

Digital Output: Controller instruction → backplane bus → microprocessor processing → optoelectronic isolation → power amplification circuit → terminal block output (driving external load).

Redundant Control Unit: Dual-CPU hot standby design, real-time data synchronization, automatic switching during faults;

Power Management: Dual 24VDC inputs, built-in DC-DC converter and power monitoring chip, supporting seamless switching;

Signal Isolation Module: Hybrid isolation of optocouplers + magnetic couplers, preventing common-mode interference and enhancing system noise immunity.

For Safety Certification: When used in SIL3-level systems, prioritize LD800HSE, matching with ABB safety controllers to achieve functional safety.

For High-Density I/O: Can parallel LD800HSE modules (up to 8 modules/framework) or flexibly expand with LD700 series (8DI/8DO).

For Anti-Interference Scenarios: In strong electromagnetic environments, recommend using LD800HSE's full isolation design, combined with shielded cables and grounding treatment.

For Cost Optimization: For non-critical process control, select the non-redundant LD800K01 version to reduce hardware investment.
