Product Description:
The 5P91457786.025-00 unit is an industrial automation computer produced by B & R Automation within the 5PC Industrial Automation Units series. Designed as a control and communication node, it connects field devices to higher-level networks and provides localized data processing for machine sequences. As a compact panel-mountable box PC, it supplies processing resources to PLC tasks, motion control, and HMI subsystems. Its compact format also helps place computing hardware close to the machine process, reducing the need for long internal wiring runs between control components.
Storage media is accommodated by a single CFast slot that accepts cards through a SATA III interface, giving the system solid-state throughput for program and log files. Serial diagnostics are handled on COM1 via RS232, with throughput capped at 115 kbit/s for legacy controllers. Two RJ45 connectors expose the internal switch fabric so the controller can exchange or forward packets at 1 Gbit/s on each link, and galvanic isolation separates these ports from system ground. Video is provided by one DisplayPort and a DVI-I panel interface, allowing independent connection to modern or legacy operator panels. The logic section is powered from a nominal 24 VDC supply, matching common cabinet power rails.
Power input is protected by an onboard fuse rated at 15 A and cleared for interruption up to 65 V DC, while the electronics draw no more than 5.5 A during full load. The housing carries an IP20 protection rating, so the unit is intended for installation inside an enclosed cabinet with controlled airflow. Five external receptacles offer removable media and peripheral access through 4x USB 3.0 + 1x USB 2.0, enabling high-speed camera links, flash drives, and service tools without opening the cabinet door. These external USB connections allow removable devices and peripherals to be attached without accessing the internal electronics. The combination of network, video, storage, and peripheral connectivity supports local visualization and machine control within a single cabinet-mounted computer.
