The BMXDDO3202K is a 32-channel solid-state output module for the Modicon X80 rack, switching 24V DC loads at 0.125 A per channel. Positive logic means the output turns on when the control signal is high. Total module current is limited to 3.2 A, so at full 32-channel loading each output must be derated below its per-channel maximum to stay within the package limit. Response time is 1.2 ms, suitable for valve banks and indicator arrays.
Protection and diagnostics
Each output is protected against reverse polarity, short circuit (requires a 2 A external fuse), overload, and overvoltage via a transil diode. Per-channel current limiting engages between 0.125 A and 0.185 A. Status LEDs give immediate visual feedback: one green RUN LED for module operation, one green LED per channel for channel status, plus red LEDs for module error (ERR) and module I/O fault.
MTBF is 290,000 hours at 40°C ambient. Vibration resistance 3 gn, shock 30 gn.
