The fiber optic link ensures data integrity across manufacturing floors, utility substations, or transportation networks.

In building automation, the MED100A can integrate legacy serial equipment like access control panels or environmental monitors into modern fiber-based networks, future-proofing infrastructure while maintaining compatibility. Its rail-mountable form factor makes it a fit for retrofitting existing DIN rail setups in telecommunications cabinets or energy management systems, providing a seamless upgrade path without extensive rewiring.

Industrial Automation

Connect RS-232/RS-485 devices such as PLCs, motor drives, or instrumentation across factory floors or outdoor sites, using fiber to bypass electrical noise and distance limitations.

Infrastructure Monitoring

Extend serial signals from remote sensors or meters in utilities, water treatment, or oil and gas facilities to central monitoring stations, ensuring reliable data collection over kilometers.

Physical Profile

The MED100A features a compact physical design optimized for industrial mounting, with dimensions of 1" (25.40 mm) in height, 2.30" (58.42 mm) in width, and 4.30" (109.22 mm) in depth. Its rail-mountable form factor allows for quick attachment to standard DIN rails, commonly used in control panels and electrical enclosures, saving space and simplifying cable management. The small footprint ensures it fits into tight installations without obstructing other components, while the durable construction supports reliable operation in varied environmental conditions.
