Schneider Electric BMXDDI6402K Modicon X80 64 Discrete Inputs 24V DC PLC I/O Module

The Schneider Electric BMXDDI6402K is a Modicon X80 discrete input module with 64 isolated 24 V DC inputs in positive (sink) logic. Each input draws 0.6 mA at 24 V DC, responds within 4 ms typical / 7 ms maximum, and supports hot swapping so a channel can be replaced without stopping the process. Power dissipation is 4.3 W across the module.

Selection Notes

The BMXDDI6402K packs 64 isolated sink-logic inputs into a single slot — four times the 16-input variant's density — for racks where panel space is the binding constraint rather than per-channel diagnostics. Unlike the lower-density inputs in the range, this module has no reverse-polarity protection, so field wiring polarity must be verified during commissioning instead of relying on the module to absorb a miswire. Its 40,000 Ohm input impedance and 0.6 mA draw per channel suit standard 2-wire proximity sensors and dry contacts, not high-leakage wiring runs.
