The B & R Automation X20IF1072 is a CAN Bus interface module from the X20 Fieldbus Input Output Modules series, supporting a maximum bus rate of 1 Mbit/s and one interface port. It operates in temperatures from -25°C to 60°C horizontally and features IP20 protection, with shock resistance up to 15 g. The module also tolerates up to 95% relative humidity in non-condensing environments and can be used at elevations up to 2000 meters.

Product Description:
B&R Automation manufactures the X20IF1072, an interface module in the X20 Fieldbus Input Output Modules series. Installed on a base carrier within an X20 slice, the unit provides a physical connection between decentralized sensors, actuators, and the higher-level controller. Its role in industrial automation is to let the controller exchange process data across a field network without adding local processing delays at the I/O station. Because it is a dedicated interface module, it focuses on communication rather than local signal conditioning or application logic.
The module exposes 1 communication interface based on the CAN Bus protocol. Data moves through that port at up to 1 Mbit/s, allowing deterministic exchange of short control frames that are common in distributed I/O systems. This makes it suitable for machine sections that require predictable updates between field devices and the main controller. The housing has an IP20 rating, so the module is intended for cabinet installation where conductive dust and moisture are excluded. Shock resistance up to 15 g helps protect the electronics during transport or machine impacts, while continuous vibration tolerance of 1 g helps reduce contact fretting during normal operation. The overvoltage category is II, which suits installation on the load side of a building distribution system.
The module starts reliably at −25 °C and can operate in a horizontal orientation until the internal temperature reaches 60 °C. It also remains suitable for installation at elevations up to 2000 m, where lower air density can reduce convective cooling inside a control cabinet. Relative humidity may reach 95% as long as condensation does not form, and vertical mounting lowers the allowable operating temperature because airflow along the PCB is reduced. These operating limits should be observed when the module is installed as part of a larger X20 backplane assembly with adjacent electronic modules.
