The Schneider Electric BMXDDO1602H is a 16-point solid-state output module for the Modicon X80 platform, delivering 24 V DC positive logic at 0.5 A per channel with a module total of 10 A. It is built for severe environments with conformal coating and a wide operating temperature range from -25 to 70 °C. Each output is protected against short circuit (via a 2 A external fuse), overload (with an electronic circuit breaker), overvoltage (via transil diode), and reverse polarity (via diode). Response time is 1.2 ms, and dielectric strength between output and ground is 1500 V AC for one minute. LED diagnostics give instant status: a green RUN LED, a red ERR LED for module error, a red I/O LED, and a green LED per channel for channel diagnostic.
Lifecycle and spares posture
For existing Modicon X80 installations, this module is a direct drop-in replacement for 16-point positive-logic output slots. No last-time-buy or obsolescence watch required today.
Installation and commissioning notes
The module draws 79 mA from the 3.3 V DC backplane. It occupies a single slot in an X80 rack and is rated IP20. Ensure the external 2 A fuse is fitted per channel for short-circuit protection; the module also provides overload and overvoltage protection internally. Outputs are positive logic (sourcing) and can be paralleled for higher current up to two channels maximum. Watch the load impedance: ohmic loads above 48 Ω are specified for the output stage.
