Black Box Industrial DIN Rail RS-232/RS-422/RS-485 to Fiber Driver

The Black Box Corporation MED101A Industrial DIN Rail RS-232/RS-422/RS-485 to Fiber Driver provides reliable data transmission over fiber optic cables, supporting serial signals up to 115.2 kbps for RS-232 and up to 460.8 kbps for RS-422 or RS-485. Its fiber optic technology makes it immune to electromagnetic interference (EMI), radio frequency interference (RFI), and transient surges, making it an ideal solution for environments with heavy electrical noise or radio interference. This device effectively replaces traditional converters and isolators when connecting remote equipment, simplifying system architecture while maintaining signal integrity. It is compatible with Modbus ASCII and RTU protocols and features automatic send data control, eliminating the need for driver software, which streamlines installation and operation. The unit includes removable terminal blocks for ease of wiring and can be conveniently mounted on an optional DIN rail, offering flexible deployment options in industrial settings. Designed for harsh environments, the MED101A operates reliably within a wide temperature range from -40°F to +185°F, and features three-way isolation with 2000-volt input/output protection to safeguard connected devices. Built with user-friendly indicator LEDs, it provides real-time monitoring of signal and power status. Its extended ambient operating range from -40°F to +176°F ensures consistent performance in extreme conditions. The device supports data-derived or RTS transmit/receive switching (RS-485), allowing versatile communication configurations such as point-to-point or ring topologies. UL approved and backed by a five-year limited warranty, the Black Box MED101A is a robust solution for industrial data communication needs, especially in environments prone to electrical interference.
