Product Description:

The M2400 parallel I/O module is manufactured by Beckhoff and belongs to the M Parallel I/O Modules series. It serves as a compact signal concentrator that attaches to a DIN rail and exchanges process data with a Beckhoff master through the system bus. With integrated analog and digital channels, the unit allows a controller to read sensor values and drive actuators in real time without requiring separate interface cards, simplifying cabinet layouts in machine tools, packaging lines, and material-handling cells.

Power to the module is supplied at 24 V DC, and it draws a steady input current of 0.1 A. The system bus refreshes process images every 25 µs, while an internal watchdog resets the outputs if no command arrives within 100 ms. Each analog output sources or sinks signals over a range of ±10 V with a 12-bit conversion resolution; a linearity error confined to ±1 LSB maintains accuracy across the span. Fast response is supported by a 10 µs rise time, and the digital front end recognizes state changes after an input delay of 0.7 ms. Serial communication with the backplane occurs at 2.5 Mbaud, allowing the device to keep pace with motion loops that demand submillisecond feedback.

The module provides 4 voltage outputs and 16 digital channels that can be individually configured as inputs or sourcing outputs. Each sourcing line can deliver up to 500 mA to solenoids or indicator lamps. A hardware latch captures transient edges for 6.8 ms, preventing high-speed pulses from being missed by slower controllers. The enclosure measures 270 × 76 × 68 mm, and the device weighs 1100 g, allowing it to fit beside power supplies without placing excessive stress on panel supports. Minimal cabling delay and a bus cycle aligned with the stated timing parameters support precise synchronization when the module is installed in distributed I/O blocks on extended machines.
