7XV124.50-11
The B & R Automation 7XV124.50-11 FO converter is a compact member of the 7XV Remote Valve Terminals series, engineered for precise digital control and reliable industrial operation. This module supports RS232 communication and multimode fiber types, delivering transmission rates up to 115.2 kbit/s over distances reaching 2 km. Designed for robust deployment, it features an IP20 protection degree and operates within an ambient temperature range of 0 to 55°C. With a lightweight form factor of 56 g and mounting flexibility in both horizontal and vertical orientations, the 7XV124.50-11 simplifies integration in space-constrained panels. The device ensures scalable performance in industrial automation, balancing durability and precision.
Technically, the 7XV124.50-11 utilizes a high-side driver (source) digital output configuration to deliver a stable current output of 0.1 A per channel and a digital output operating current of 2.4 A nominal. The switching voltage tolerance is 24 VDC ±25%, supporting fluctuating supply conditions common in factory environments. With a switching frequency of 100 Hz and input capacitance of 47 μF on both module and I/O power supplies, the terminal maintains signal integrity under dynamic loads. The module’s installation employs a 25-pin DSUB connector with 4-40 UNC screw mounting, while system communication is handled via an 11-pin male multipoint X2X Link slave interface that also serves as the bus connector. A status LED array, including a DCOK LED indicator, provides real-time diagnostics for power and data link health.
Operationally, the 7XV124.50-11 is qualified for a transit temperature range of -20 to 70°C, ensuring resilience during shipping and storage. The terminal’s compact dimensions of 63 x 59 x 20 mm (including mounting plates) and total weight of 56 g reduce mechanical load and facilitate rapid field servicing. Its IP20 rating protects critical electronics against inadvertent contact, while the rugged DSUB and fiber optic interfaces withstand repeated mating cycles. The integrated driver topology and fiber converter design minimize electromagnetic interference, enhancing reliability in industrial control loops and valve actuation systems.
The 7XV124.50-11 integrates seamlessly with B & R's automation platforms, supporting direct bus connection through its X2X Link interface and eliminating the need for external power bridges. Its design aligns with modular cabinet architectures for packaging machinery, process skids, and distributed I/O assemblies. With support for multimode fiber and RS232, this module is ideal for remote valve control, safety shutdown circuits, and distributed monitoring in industrial automation scenarios requiring high signal integrity and extended reach.
