Schneider Electric BMXDDO3202K Modicon X80 Discrete Output Module

Product Overview

The Schneider Electric BMXDDO3202K is a high-density, 32-channel discrete output module specifically engineered for the Modicon X80 automation platform. This module serves as a critical interface in Modicon M340 and M580 PLC systems, allowing the controller to manage multiple field devices simultaneously. By utilizing solid-state transistor technology, the BMXDDO3202K offers rapid switching speeds and a significantly longer operational life compared to traditional relay modules. Its compact, single-slot design is ideal for space-constrained control cabinets where high I/O density is required.

Functional Capabilities

• High-Density Control: Provides 32 discrete output channels in a single slot, effectively doubling the capacity of standard 16-channel modules and reducing the physical footprint of the PLC rack.
• Solid-State Reliability: Features 24V DC transistor outputs with Positive Logic (Source). This design ensures that when an output is active, the module “sources” current to the load, which is a standard safety preference in many industrial regions.
• Electrical Precision: Maintains high efficiency with a low voltage drop (less than 1.5V) and minimal leakage current (less than 0.1mA), ensuring that connected actuators like solenoids or indicators receive clean, stable power.
• Robust Isolation: Offers superior electrical safety with an insulation resistance exceeding 10MΩ at 500V DC. This isolation prevents electrical noise or faults in the field from affecting the sensitive backplane electronics.
• Thermal Management: Engineered for energy efficiency, the module dissipates only 3.6W of power at full load. This low heat output allows it to operate reliably in ambient temperatures up to 60°C (140°F) without external cooling.
