USR-CAN112
USR-CAN112 Converter
The USR-CAN112 is a DIN-rail RS232-to-CAN converter for bidirectional communication between one RS232 port and one CAN interface. Its official specification lists CAN 2.0A/2.0B, 5 Kbps–1 Mbps CAN baud, 600 bps–230.4 Kbps serial baud, five conversion modes, 14 filter groups, 5–24 VDC input, and -40 to +85 °C operation. Selection and availability are confirmed at RFQ.
