Module in the X80 rack
The BMXDDO3202 is a solid‑state discrete output module for the Modicon X80 platform, delivering 32 positive‑logic outputs at 12…24 V DC, each rated 0.55 A and individually protected against overload, short‑circuit (external fuse required), overvoltage (transil diode), and reverse polarity. Maximum module current is 17.6 A; parallel up to three outputs for higher load current. Response time is 0.3 ms. It draws 56 mA at 3.3 V DC from the backplane, dissipating 4.8 W. Operating temperature 0…60 °C, storage –40…85 °C, 5…95 % RH non‑condensing. Vibration 3 gn, shock 30 gn. Altitude 0…2000 m standard, 5000 m with derating.
On‑board diagnostics include a green RUN LED, per‑channel green channel diagnostic LEDs, a red module error (ERR) LED, and a red module I/O LED.
Integration notes
Mount in an X80 rack slot; the module uses an external fuse for short‑circuit protection. Load impedance must exceed 54.54 Ω for ohmic loads. Maximum leakage current in state 0 is 0.1 mA; voltage detection threshold for preactuator fault is below 14 V DC and for preactuator at state 0 above 18 V DC. Output overload is handled by an electronic circuit breaker (1.5 In < Id < 2 In) and a current limiter.
