Product Description:

The M-1410 000 is a parallel I/O extension module produced by Beckhoff within the M Parallel IO Modules series. The unit converts field signals into a fiber-optic format and returns them to the controller, enabling galvanic isolation and long-distance transmission inside decentralized automation cells. By presenting two eight-bit ports, it fits into Beckhoff’s modular signal concept where compact DIN-rail devices are combined for machine monitoring and interlock tasks. Its role is to aggregate discrete sensor and actuator states and relay them deterministically to higher-level PLCs.

Deterministic communication is governed by a telegram cycle of 25 µs, so the controller can refresh all sixteen channel states during every scan of a high-speed motion program. Serial data leaves the module over a fiber link at 2.5 MBaud, minimizing electromagnetic interference in noisy cabinet environments. Logic circuitry is powered from a field supply of 24 VDC; from that rail the module can source up to 500 mA for connected sensors while drawing only 0.1 A itself when idle. The dual 8-bit format simplifies address mapping, and three diagnostic LEDs show link integrity, internal faults, and watchdog status without additional tools.

The optical medium further extends placement flexibility. With standard glass fiber, the permissible span reaches 600 m, while multimode plastic or H-CS fiber can bridge machines up to 45 m. Outputs switch to a safe state if no valid frame arrives before the watchdog elapses at 100 ms. Mechanical integration is straightforward because the housing clips onto rail profiles that meet DIN EN 50022/50035, and a 30 mm minimum bend radius preserves the fiber’s attenuation budget. Sixteen channel LEDs at the front show individual bit activity so channel status can be checked directly at the module.
