BOM & application review — reply in 1 business day

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.

Frequently asked

What serial and CAN interfaces does the USR-CAN112 provide?

The official PUSR selection table identifies USR-CAN112 as the variant with one RS232 interface and one CAN interface, both using push-type terminal wiring.

What baud rates does the USR-CAN112 support?

The official specification lists a CAN baud range of 5 Kbps to 1 Mbps and a serial baud range of 600 bps to 230.4 Kbps.

Which conversion and filtering modes are available on USR-CAN112?

PUSR lists transparent, transparent-with-ID, standard-protocol, Modbus RTU, and custom frame-header or frame-trailer conversion, plus up to 14 custom frame-ID filter groups.

Can USR-CAN112 replace another RS232-to-CAN converter?

USR-CAN112 may be evaluated as a candidate replacement, subject to engineering review of wiring, baud rates, frame handling, termination, power, environment, and protocol requirements.
