PLCs, Power Supplies & Others

The Schneider BMXDDI3202K reads 32 discrete field signals for M340 PLCs. This module belongs to the Modicon M340 product family. You will find this input board in factory automation and machine control applications. It handles pushbuttons, limit switches, and proximity sensors efficiently.

Manufacturer: Schneider Electric
Series: Modicon M340
Category: Discrete Input Module (32-Channel, 24V DC)

Physical Dimensions and Weight

The Schneider BMXDDI3202K measures 3.9 inches in height. Its width reaches 1.1 inches for single-slot occupancy. The depth goes to 3.4 inches including the connector. This compact design fits into any M340 rack. The total weight comes to approximately 0.2 kilograms.

Technical Specifications and Channel Configuration

This discrete input module provides 32 non-isolated input channels. Each channel accepts 24V DC signals from field devices. The module groups channels into four blocks of eight. A green LED indicates the status of every input channel. Therefore, you can see field signal states at a glance.

Signal Processing and Noise Immunity

The Schneider BMXDDI3202K includes built-in input filtering for noise rejection. An RC filter removes high-frequency interference from each channel. The module meets IEC 61131-2 standards for industrial environments. Consequently, you get reliable readings even near motors and drives. You can adjust the input delay through software configuration.

Interface and Connectivity

This input module uses a 28-pin removable terminal block for wiring. The block accepts 14-24 AWG wire easily. A removable labeling strip helps you document each channel assignment. Thirty-two LED indicators show the status of all inputs. You can diagnose wiring problems without a programming device.

Component Layout and Construction

The Schneider BMXDDI3202K contains 85 discrete components on a four-layer PCB. Key parts include 32 optocouplers and 64 resistors. Each channel uses one LED for redundant status indication. All components meet industrial temperature ratings from 0°C to +60°C. This robust construction ensures reliable operation for many years.

Energy Storage and Protection

This discrete input module includes a capacitor bank for transient protection. Each channel has 0.01 microfarads of energy storage capacitance. These capacitors absorb voltage spikes up to 1,000V for 1 microsecond. Additionally, the board protects against reverse polarity on the power supply. A built-in fuse prevents damage from external overcurrent conditions.

Integration and Compatibility

Use the Schneider BMXDDI3202K with any Modicon M340 CPU module. It works alongside BMXDDO3202K discrete output modules. This input module supports all standard M340 rack configurations.
