Product Description:

The 4C1100.01-510 is a communication interface module produced by B&R Automation for the 4C PanelWare Panels series. It mounts behind an operator panel and functions as a Profibus-DP slave node that exchanges data over RS485 or RS422 with the higher-level PLC. Within an industrial line, the module supplies galvanically isolated serial signaling and provides the physical connector needed for quick field wiring, allowing PanelWare terminals to integrate with motion controllers, drives, and distributed sensors without additional gateway hardware.

This module has a front width of 182 mm, a height of 86 mm, and a depth of 30 mm, so it fits shallow operator enclosures while still leaving space for cable bends. The 9-pin D-type socket on the housing brings all Profibus and service lines to a single shielded plug, which helps reduce electromagnetic noise. At a nominal supply of 24 VDC, the electronics draw 60 mA, a value that permits daisy-chaining several panels from a standard 24 V cabinet supply without overloading auxiliary power fuses. The RS485/RS422 transceivers are configured for the selected protocol; for Profibus, the port supports a fixed bus speed, while pure RS422 diagnostics can run concurrently at 38.4 kBaud.

Input power can vary from 18 VDC to 30 VDC, giving adequate headroom for starts and brownouts on long cable runs. The upper limit helps protect the circuitry from unregulated supplies, while the lower limit helps keep the panel active during voltage dips. Rated service temperature extends up to 50 °C, so the unit can reside in fanless sealed panels near process equipment. On the communication side, it keeps the Profibus link locked at 187.5 kBaud in the slave role, allowing deterministic cyclic data while higher diagnostic traffic is routed through the secondary RS422 channel.
