Product Description:
The 4C2001.01-510 belongs to the 4C PanelWare Panels series manufactured by B & R Automation. Installed behind customized operator fronts, this controller acts as the processing core for a single display module and multiple keypad segments, handling screen refresh, key scanning, and data exchange with higher-level PLCs in an HMI architecture. In industrial automation, it coordinates user input, displays machine status, and forwards commands while minimizing wiring requirements and cabinet depth.
The electronics are powered by a nominal 24 VDC supply, but the design tolerates input voltage as low as 18 VDC and as high as 30 VDC. At nominal voltage, the logic draws only 110 mA, allowing it to operate from a low-current power supply. The controller supports one display module and up to seven keypad modules connected through the internal bus, allowing the panel size to scale without requiring a different CPU board. Memory includes 256 kB of system ROM, 256 kB of user ROM for application code, and 256 kB of battery-backed user RAM for variables that must remain available after a power cycle. These memory areas store graphic objects, key assignments, application instructions, and communication tables used during real-time operation.
The unit communicates with external devices through two RS-232 channels and one isolated RS-422/RS-485 port. These interfaces enable separate connections to devices such as a drive, barcode reader, and supervisory computer, while the isolated port helps prevent communication problems caused by ground loops. The controller can operate at temperatures from 0 °C to 50 °C. Noncondensing relative humidity can range from 10 % to 95 % during operation. For storage or transportation, the unpowered board can withstand temperatures from -20 °C to 60 °C, allowing it to be kept in warehouses without continuous climate control.
