The B&R Automation BRCOMP1-0 is a compact PLC controller engineered for industrial automation requiring flexible I/O and multi-protocol connectivity. Built on a 6303 processor, it delivers instruction execution at approximately 4 msec per K instruction and operates from a 24 VDC supply drawing 6.5 W. The controller combines 16 KByte application EEPROM, 16 KByte expansion EEPROM, and 16 KByte instruction SRAM to support complex automation logic.
