AEG AS-BDEP-218
- Product Introduction: AEG AS-BDEP-218 is a high-density 16-channel digital output module with electromechanical relay outputs, designed for the Modicon 800 series PLC systems. Engineered for general-purpose industrial control applications, the module provides isolated dry contact outputs for controlling AC/DC field devices, eliminating the need for additional signal conversion components and enabling seamless integration with both low-voltage DC and line-voltage AC equipment. It features channel-to-group isolation, comprehensive fault protection, and a compact modular design, with individual LED status indicators for each channel. The module is ideal for high-density output control in factory automation, building automation and process control applications where reliable switching of mixed AC/DC loads is required.

- Functional Features:
- 16-channel relay output design provides high-density dry contact switching, enabling control of 16 field devices in a single compact module and saving significant PLC chassis space. SPST normally open relay contacts support mixed AC/DC loads (24 V DC to 230 V AC), eliminating the need for separate DC and AC output modules and reducing system hardware costs. 8-channel isolation groups prevent electrical interference and ground loops between different load groups, ensuring reliable operation in noisy industrial environments and protecting the PLC system from line-voltage transients. Individual LED channel status indicators provide instant visual feedback on relay energization status, enabling quick on-site troubleshooting and system commissioning. High mechanical and electrical relay life ensures long-term reliable operation, minimizing maintenance and replacement costs for industrial applications with frequent switching requirements. 2500 V AC group-to-group and 3000 V AC channel-to-backplane isolation provides robust protection for the PLC system from high-voltage field side transients and surges. Compact modular design with standard Modicon 800 series chassis interface enables plug-and-play installation and easy system expansion, with hot-swappable support for module replacement without chassis shutdown. Surge and overvoltage protection on all output channels prevents relay damage from electrical transients common in industrial AC power systems. The module’s low power consumption reduces overall PLC chassis power draw, complying with industrial energy efficiency standards. Seamless integration with Modicon 800 series remote I/O racks enables distributed relay output control, reducing cable runs to high-voltage field devices and improving system safety.
