Product Description:

The 4PP065.IF231/BLM is a power panel assembled by B&R Automation within the 4PP Power Panels series. The unit functions as a compact operator interface that combines visualization and fieldbus routing, allowing a machine controller to exchange data with distributed drives, sensors, and expansion modules over either serial links or a CAN bus. In an automation cell, it is mounted inside the control cabinet and provides parameter entry, status feedback, and transparent gateway access between the machine network and higher-level systems.

Two communication groups are available: one CAN channel and one multi-standard serial channel that can be configured as RS232, RS422, or RS485. The CAN node is managed by an SJA 1000 controller connected through a 4-pin male multipoint plug, and its integrated switchable termination simplifies star or trunk wiring. Data can be exchanged at up to 1 Mbit/s, and the physical segment can span 1000 m when the data rate and cable impedance are matched. The serial side uses a 9-pin DSUB that carries either single-ended or differential signals. RS232 transfer reaches 15 m at 19,200 bit/s, while all three serial modes share a ceiling of 115.2 kbit/s. An IP20 protection rating restricts installation to dry enclosures and indicates that only basic touch protection is provided.

The housing is fixed to a mounting plate with screws tightened to 0.6 Nm maximum, and staying within this limit helps prevent thread damage while preserving the seal between conductive surfaces. Once secured, the panel adds only 57 g to the cabinet mass, which supports layouts where several small HMIs occupy a single door. For long serial runs, the RS485/RS422 differential pair can drive up to 500 m of shielded cable, and its onboard termination removes the need for external resistors at the panel end. The RS232 branch remains limited to 15 m but offers quick point-to-point service for a laptop or a legacy PLC interface.
