The BMXDDO1602 is a Modicon X80 discrete output module with 16 transistor outputs, 24V DC positive logic. Each output is rated 0.5 A (0.625 A per channel with external fuse), and the module can deliver up to 10 A total. Response time is 1.2 ms, and the outputs are short-circuit and overload protected via electronic circuit breaker and current limiter. Diagnostic LEDs include a green RUN LED, a green channel LED per output, a red ERR LED, and a red I/O LED. This gives immediate field visibility of module health and per-channel status without a software scan.
Integration Notes
Power draw is 79 mA at 3.3 V DC from the backplane. Per-channel output can be paralleled (max 2 outputs) for higher current – ensure the application stays within the module total of 10 A. The module requires a 2 A external fuse per output group for short-circuit protection; reverse polarity and overvoltage protection are built in. Outputs are positive logic (sourcing), so loads are switched by the output sinking current. Off-state leakage is 0.5 mA, which may cause faint glow on LEDs or slow drop on small relays. The module is IP20 rated, for use inside a control cabinet.
