UOTEK UT-2501 RS-232 to CAN BUS Data Converter

SKU CH-9FGY-R7JQX

Industrial RS-232 to CAN bus converter with optoelectronic isolation and 1,200 m CAN bus range

  • TypeCANBUS ADAPTER
  • Industrial-grade isolation protects equipment from ground loops and surges
  • Half-duplex asynchronous mode supports 300 to 115.2 kbps data rates
  • CAN bus reaches over 1 200 m on twisted-pair or shielded cable
  • Compact 63 × 33 × 17 mm enclosure fits tight panels
  • Operates reliably from -40 to 85 °C in 5 to 95 % humidity

Industrial RS-232 to CAN Bus Converter

The UOTEK UT-2501 bridges EIA RS-232 and CCITT V.24 asynchronous devices to CAN bus networks. It targets engineers integrating legacy serial equipment into industrial automation or vehicle diagnostics systems. Optoelectronic isolation protects connected hardware from ground loops and surge interference up to the rated limits.

Replaces direct RS-232 links needing longer reach

Swap a short 5-metre RS-232 cable for this converter when the CAN bus side must span more than 1,200 metres over twisted-pair or shielded cable. The jump is worth it when half-duplex asynchronous operation at 300 to 115.2 kbps satisfies the protocol timing and isolation is required between device grounds.

Handles 300 bps to 115.2 kbps across wide

Comfortable operating range spans -40 to 85 degrees Celsius with 5 to 95 percent relative humidity. The RS-232 port remains limited to 5 metres while the CAN bus port extends past 1,200 metres. Miniature 63 by 33 by 17 mm enclosure fits tight panels but offers no full-duplex mode or faster signalling.

Questions about this item

What are the physical dimensions of the UT-2501 converter?

The unit measures 63 mm long, 33 mm wide and 17 mm high, so it fits in tight enclosures or on a DIN rail bracket.

How do I connect the CAN bus side and which wiring mistake should I avoid?

Use the DB9 male or the terminal block for twisted-pair or shielded cable; the common error is leaving the CAN ground floating, which breaks the isolation.

What ongoing care does the optoelectronic isolation and TVS protection need?

No scheduled maintenance is required; inspect terminal-block screws and cable shielding periodically for corrosion or loosening in harsh environments.
