Internal Product Review
The 3IF722.9 is a B & R Automation System 2005 controller interface module with an aPCI slot format and IP20 protection. The If1 channel supports 115.2 kbit/s over 1200 m, giving the module dependable long-distance serial communication. CAN Bus support on If2 at 500 kbit/s makes this unit especially appealing for responsive distributed control.

Product Description:
The 3IF722.9 is a communication interface card produced by B & R Automation for the System 2005 Controllers series. Installed in an aPCI expansion slot of the host CPU, the module adds serial and fieldbus channels that link the controller to distributed I/O, drives, and operator stations across a plant network. By providing multiple electrical layers on one board, it supports deterministic data exchange required for coordinated motion and process tasks.
Interface 1 occupies a 9-pin female DSUB connector and carries a balanced serial link that can operate up to 115.2 kbit/s. This channel remains reliable over cabling runs of 1200 m because it uses the differential signaling of RS485/RS422. The second port uses a 4-pin male multipoint plug for a CAN bus segment. At 500 kbit/s it handles medium-speed cyclic traffic, and its galvanic design supports network trunks reaching 1000 m without repeaters. All field wiring leaves the controller through standard pluggable terminals, simplifying service. The card follows the aPCI form factor, so installation requires no back-plane adapters and the host retains hot-swap capability with messaging defined by CAN Bus.
Power consumption stays low: the logic domain draws 0.74 W from the 3.3 V rail, and the transceiver section needs 1.0 W at 5 V, giving a combined load of 1.74 W on the System 2005 supply. The module is housed in an enclosure rated at IP20, so it must be mounted inside a closed cabinet. A third communication path, accessible through a 4-pin male multipoint plug, offers point-to-point or multidrop traffic over balanced lines; it sustains cable lengths of 1200 m and relies on RS485 signaling for noise immunity. With these additional channels the card complements the higher-speed and slower serial interfaces described earlier while keeping thermal impact negligible.
