AEG 6390-042.708853 Industrial Grade PLC Backplane Bus Extender Module
- Product Introduction: This is a high-performance backplane bus extender module for AEG Modicon medium and large PLC systems, engineered to extend the transmission distance of the PLC chassis backplane bus and realize reliable data communication between multiple cascaded PLC chassis. It optimizes bus signal transmission, reduces signal attenuation and interference in long-distance transmission, and is a core accessory for building large-scale distributed industrial control systems with multi-chassis expansion requirements.
- Technical Specifications:
- Bus Compatibility: AEG Modicon 984/884 series high-speed parallel backplane bus, support 10 Mbps original bus rate.
- Extension Distance: Single segment maximum 5 meters, up to 4 segments cascaded with a total extension distance of 20 meters.
- Connection Interface: D-sub 25-pin male/female industrial connectors, gold-plated pins for low contact resistance.
Detailed content
-
- Power Supply: 24 VDC, power consumption ≤3 W, voltage tolerance ±15%.
- Isolation Performance: 2500 VAC electrical isolation between input and output bus signals, anti-interference attenuation ≥80 dB at 1 MHz.
- Operating Temperature: -25°C to +70°C; Storage Temperature: -40°C to +85°C.
- Protection Rating: IP20; Dimensions: 90mm × 120mm × 50mm (W×H×D); Weight: 0.45 kg.
- Mounting Method: Standard 35mm DIN rail mounting, compact design for cabinet space saving.
- Functional Features:
- High-fidelity bus signal amplification ensures the original transmission rate and data accuracy of the backplane bus during long-distance transmission, without reducing the system response speed.
- Independent electrical isolation between input and output effectively isolates the electromagnetic interference between different PLC chassis, preventing fault spread between cascaded modules and improving system stability.
- The gain-adjustable signal amplifier adapts to different cable types and transmission distances, realizing flexible configuration of bus extension according to on-site installation conditions.
- Industrial-grade D-sub connectors with locking structure ensure firm connection, effectively preventing signal disconnection caused by industrial site vibration and mechanical impact.
- Built-in bus fault detection function, real-time monitoring of bus signal strength and transmission status, LED indicators for normal operation, signal weak and fault status for quick troubleshooting.
- Low power consumption design does not increase the overall power load of the PLC system, and the wide voltage tolerance of the power supply adapts to the unstable 24 VDC power supply in industrial sites.
- Fully compatible with AEG Modicon 984/884 series PLC chassis, plug-and-play without additional software configuration, reducing on-site debugging time.
- The metal shell with electromagnetic shielding design further enhances the anti-interference performance of the module, adapting to harsh industrial environments with high electromagnetic radiation such as steel mills and chemical plants.
- Application Scenarios: Widely used in large-scale distributed industrial control systems that require multi-chassis expansion of AEG Modicon PLC, such as automobile assembly line multi-station control, petrochemical plant workshop-level distributed process control, metallurgical factory smelting line multi-equipment linkage control, and port cargo handling system multi-silo control. It is also applied in municipal large-scale water supply and drainage systems and power plant auxiliary system distributed control, realizing reliable data transmission between PLC chassis in different physical locations, and is especially suitable for industrial sites where the PLC control cabinet is scattered and the distance between chassis exceeds the standard backplane bus transmission range.
