Product Description:

The M-1400-003005/8 belongs to Beckhoff's M Parallel IO Modules series and functions as a discrete signal interface for PLC-controlled equipment. The module consolidates multiple 24 V DC field signals into a single high-speed backplane connection, allowing programmable controllers to read or drive industrial sensors and actuators without additional wiring complexity. Serial communication with the higher-level controller is handled over the module bus at a sustained 2.5 MBaud transmission rate. It is suited to control cabinets where many digital points must be grouped in one place while keeping controller communication centralized.

Each port on the unit carries 8 bits, and the housing provides a total of 32 I/O channels, so a single module can manage four complete 8-bit ports. During data refresh, a 32-bit word is scanned with a 25 µs cycle time, which supports deterministic reaction to machine events. Logic electronics are powered from a 24 V DC supply voltage that can fluctuate by ±10%, while the same voltage level is routed to field devices as the 24 V DC input and output reference. Input circuitry draws 10 mA per channel, and outputs can source up to 24 V DC at 500 mA, while field drivers are protected by per-channel current limiting.

The module's 0.7 ms RC input delay filters contact bounce before the 6.8 ms input latch stores a stable state for logic processing. A supervisory timer resets the outputs if no command is received within the 100 ms watchdog time, which helps prevent unintended motion. In quiescent state, the electronics draw a 0.1 A no-load current, yet each output can deliver up to the 500 mA maximum output current when actuating solenoids or indicator lamps. The housing measures 76 mm in height, 68 mm in depth, and 270 mm in width, so panel layouts must allow a narrow but elongated slot on the DIN rail.
