The BMXDDO6402K (BMX-DDO-6402-K) is a high-density 64-channel discrete output module for the Schneider Electric Modicon M340 and M580 platforms. Designed for large-scale automation, it delivers reliable 24V DC transistor outputs to drive solenoids, relays, indicators, and other low-power actuators. Its single-slot design maximizes control cabinet space while maintaining fast and precise switching performance.
Featuring internal short-circuit and overvoltage protection per output group, this module ensures long-term reliability in demanding industrial environments. The "K" revision meets modern EMC and vibration standards, making it suitable for 24/7 manufacturing operations. The BMXDDO6402K interfaces via two 40-pin HE10 connectors, typically paired with Telefast pre-wired cabling, allowing organized, error-free wiring for high-density applications.

Compatible with BMXFTW pre-formed cables or Telefast ABE7 wiring systems.
HE10 connectors translate to labeled screw-terminal strips for fast and accurate field wiring.
LED indicators provide real-time status feedback for diagnostics and maintenance.
How is the 0.1A per channel limit managed?
The BMXDDO6402K is intended for low-power signaling. For larger actuators or high-power loads, use interposing 24V DC relays to prevent exceeding the transistor output rating.
Can this module be hot-swapped in an M340 or M580 rack?
Yes. The module supports online replacement, provided the PLC configuration in the software allows it. This enables safe replacement without shutting down the entire rack.
