SCHNEIDER ELECTRIC BMXDDO3202K OUTPUT MODULE

High-Speed Digital Control with Modicon BMXDDO3202K Output Module

The BMXDDO3202K is a high-performance 32-channel digital output module designed for use in the Modicon X80 system. Built with solid-state technology, it delivers fast and dependable switching for industrial automation applications.

Each of the 32 discrete outputs supports positive logic and operates at a nominal 24 VDC, making it ideal for standard automation voltage levels. The supported voltage range from 19 V to 30 V DC offers flexible compatibility in demanding environments.

With a current capacity of 0.125 A per channel and 3.2 A per module, the module ensures sufficient drive for various types of loads. It also includes output paralleling for up to three channels, expanding its usage in higher power scenarios.

Engineered for protection and longevity, this module comes with built-in features like reverse polarity protection, short-circuit protection, and overload safeguarding using advanced circuitry. These protections contribute to a longer service life and minimize system downtimes.

The voltage detection thresholds ensure accurate fault monitoring, with a pre-actuator fault detection under 14 V and a safe state detection over 18 V. These thresholds help to identify abnormal conditions early and protect the system from further damage.

Response time is a key factor in high-speed applications, and the BMXDDO3202K delivers with a fast 1.2 ms switching time. Whether for time-critical machinery or safety interlocks, this speed ensures reliable and consistent performance.

LED indicators simplify module monitoring. A green RUN LED shows module operation, while each channel features its own green diagnostic LED. A red ERR LED and red I/O LED indicate faults, ensuring quick visual diagnostics.

To support extreme environments, the module operates in temperatures from 0 to 60°C, with storage capability from -40 to 85°C. It is resistant to vibration (3 gn) and shock (30 gn), making it suitable for harsh industrial settings.

Compliance with the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU) assures users of the module’s adherence to stringent safety and electromagnetic standards. This makes integration easier and more compliant globally.

Internally, the BMXDDO3202K boasts a power dissipation of only 3.6 W, contributing to energy-efficient system design. This helps maintain stable temperatures in densely packed control cabinets.

With an MTBF of 290,000 hours, the module offers exceptional reliability and minimizes the need for frequent replacements or servicing. This is especially useful in systems requiring continuous uptime.

The IP20-rated housing provides basic protection against dust and solid objects. For applications needing higher protection levels, it’s recommended to install it inside a protective enclosure or cabinet.

Its solid-state outputs ensure minimal voltage drop (<1.5 V) and low leakage current (0.1 mA) when off, offering efficiency and accuracy in output signal control. This helps avoid unintended actuator movements in sensitive circuits.

The module also features advanced overvoltage protection using transil diodes and includes external fusing with a 2 A fuse for added safety. Together, these help safeguard both the module and connected devices from damage.

Built-in electronic circuit breakers help detect and isolate faults quickly, operating between 0.125 A and 0.185 A, depending on the situation. This ensures stable operation even during load fluctuations.

Each output must drive a minimum ohmic load of 220 ohms, ensuring proper functioning and preventing under-load situations that could affect reliability or diagnostics. The maximum tungsten load supported is 1.2 W.

Designed for flexibility, the module fits in applications up to 5000 meters altitude, though with a derating factor beyond 2000 m. This makes it adaptable for various geographic or altitude-specific industrial installations.

In terms of installation, the module is compact and lightweight, weighing just 0.11 kg. It fits neatly into the X80 system backplane, making assembly quick and maintenance straightforward.

The typical current consumption of 125 mA at 3.3 V DC ensures compatibility with the Modicon backplane’s power limits and allows easy planning for overall power distribution across modules.

Shipping and handling are efficient too. The primary packaging size is 12 cm x 11 cm x 5.4 cm, weighing about 140 g, while the bulk packaging holds 15 units per box, optimizing logistics for industrial buyers.

Its dielectric strength of 1500 V AC between outputs and ground, as well as between outputs and internal logic, ensures safe isolation and reduces the risk of electrical faults across the system.

The 500 V DC isolation between channel groups prevents crosstalk and interference, contributing to clean, reliable signal operation across all 32 outputs. This is essential for installations with mixed signal loads.

Whether you're looking to improve your machine’s response time or need a robust I/O solution for discrete control, the BMXDDO3202K module offers a balance of speed, protection, and compatibility.

Because of its solid-state design, this module is suitable for applications requiring frequent switching, reducing mechanical wear that occurs with relay-based output modules and enhancing long-term reliability.

Its diagnostic LEDs and internal fault detection features simplify predictive maintenance, allowing operators to address issues before they lead to failures, and improving operational efficiency overall.

If you’re setting up or upgrading your Modicon automation system, the BMXDDO3202K is a cost-effective, high-performance output solution for any automation scenario requiring 24 VDC control signals.

Backed by Schneider Electric’s global support and trusted quality, this module is an integral part of building robust, scalable, and future-ready automation systems.
