Black Box Innovations
Industrial DIN-rail converter handles RS-232, RS-422 and RS-485 serial signals
The Black Box Innovations MED101A is an industrial DIN rail accessory that provides RS232, RS422 and RS485 serial connectivity for automation and control systems. It mounts on standard DIN rails inside cabinets or enclosures for integration with PLCs, HMIs and field devices.
Engineers who require isolated ports, USB interfaces or protocol conversion beyond RS232, RS422 and RS485 should evaluate alternative modules. Buyers needing fibre, Ethernet or wireless backhaul will not find those interfaces here.
The single specification that determines fit is the simultaneous availability of RS232, RS422 and RS485 on one DIN rail unit. Confirm your field devices use one of these three electrical standards before specifying this adapter.
No published specifications for this item yet.
The MED101A is designed for standard industrial DIN rail mounting, securing directly onto the rail without additional brackets.
Connect each serial interface to the corresponding terminal block on the MED101A, ensuring the RS-422 and RS-485 lines are terminated correctly to avoid signal reflection.
Replace the MED101A if the serial ports fail to establish a link, show persistent data errors across RS-232, RS-422 or RS-485, or if the DIN rail clip becomes loose.
