Product Description:
The 0GH-IF050 module is a serial communication expansion produced by B & R Automation for controllers in the 0GH PLC Modules series. Installed on the PLC backplane, the module creates an electrically isolated bridge between the CPU and field devices such as drives, barcode readers, and operator stations. By adding multiple protocol choices on a compact interface card, it allows the host controller to exchange process data, diagnostics, and setpoints without adding extra rack width, supporting flexible wiring layouts in factory automation cells.
Inside the module, a RISC core manages protocol handling while keeping power draw to a maximum of 7 W, which simplifies cabinet thermal design. Three independent ports are provided, and each channel includes interface isolation to help prevent ground loops between the PLC and remote equipment. The first port supports RS-232 signaling up to 64 kBaud over cables no longer than 15 m. The second and third ports can be configured for RS-485 or RS-422, and in these modes the maximum transfer rate reaches 347 kBaud, enabling high-speed data exchange. Segment loading for RS-485 is limited to 32 transmitters, 32 receivers, and two terminators.
For longer installations, the differential pair can span 1200 m without repeaters, permitting controller placement far from the process while maintaining data integrity. The onboard dual-port RAM allocates 576 bytes for buffering telegrams, so the PLC CPU is free from tight polling loops. A current-loop TTY channel is also available, delivering 20 mA at a maximum signaling rate of 2.4 kBaud for legacy devices that cannot tolerate voltage-level interfaces. Frame formatting is flexible, with selectable data word lengths from 5 to 8 bits, parity choices listed as yes, no, even, or odd, and stop-bit options of 1, 1.5, or 2 to support proprietary protocols without additional hardware.
