The BMXDDI1602 is a high-reliability digital input module for the Schneider Electric Modicon X80 platform, compatible with Modicon M580 and Modicon M340 controllers.
It provides 16 discrete 24V DC input channels using Sink (Positive Logic) configuration for monitoring industrial field signals such as sensors, pushbuttons, and limit switches. The module features 1500 V rms galvanic isolation to protect internal logic circuits from electrical noise, ground loops, and voltage transients.
Designed for compact rack installations, it connects via a 20-way removable terminal block and supports standard industrial wiring methods.

Safety interlock status monitoring
Especially effective for high-speed discrete signal acquisition and pulse detection in industrial automation systems.
Q1: Which terminal block is required?
The module uses a 20-way removable terminal block, typically BMXFTB2000 (screw type) or BMXFTB2010 (spring clamp type).
Q2: Can it detect wire break faults?
No. For wire-break or advanced diagnostic monitoring, a diagnostic variant of the X80 input family is required.
