Product Description:
The M-1400 014 is a parallel I/O module produced by Beckhoff and assigned to the M Parallel IO Modules series. It serves as a remote digital input node in industrial automation, gathering signals from sensors or switches and passing them to a controller through the Lightbus fieldbus. By concentrating discrete wiring into a fiber-optic backbone, the module simplifies machine layouts and shortens diagnostic paths. This arrangement also keeps input collection close to field devices while sending the signal image back to the control system over the bus.
Each of the four ports communicates over the Lightbus network at 2.5 MBaud, allowing the unit to forward a full set of 32 input states with a telegram time of 25 µs. The input section is powered by 24 V DC, so wiring can remain consistent with common control voltages. Individual receiver circuits draw 10 mA and present a stable logic level to the ASIC. A Toshiba fiber connector brings the optical pair directly onto the board, eliminating separate transceivers and containing emissions. Debounce handling is inherent to the fieldbus transaction, leaving only the controller scan time to influence reaction speed. With four discrete byte-wide ports available, the module can separate machine zones while still using one Lightbus drop.
Within each port the data path is organized as 8-bit groups; the module therefore latches a refreshed image after 6.8 ms and applies a 0.7 ms RC delay that filters contact chatter before serialization. Electronics consumption stays at 0.1 A, reducing cabinet power demand during continuous polling. Fiber-optic reach extends to 600 m when glass cores are selected, whereas multimode plastic runs are limited to 45 m. Every installation must observe a 30 mm minimum bend radius so that return loss and attenuation remain inside Lightbus tolerances.
