B&R Automation BRCOMP1-0 Compact PLC Controller

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. ## Technical Specifications Processing & Memory • 6303 processor • 16 KByte application EEPROM • 16 KByte expansion EEPROM • 16 KByte instruction SRAM • ~4 msec per K instruction execution time Digital I/O • 16 digital inputs: 24 VDC, 2 msec response, sink configuration • 4 inputs function as counter inputs up to 20 kHz • 14 transistor outputs: 24 VDC, 1 A per output Analog I/O • 2 analog inputs: 16-bit resolution, configurable per channel (±10 V, 0–20 mA, KTY10 sensor −50 to +150 °C, 0–65 kOhm resistance) • 2 analog outputs: 12-bit resolution (±10 V or 0–20 mA based on connection) Communication Interfaces • RS232 Serial Interface 1 (non-isolated) • RS232/RS485 Serial Interface 2 (RS485 electrically isolated, network-capable) • PATA interface for MINICONTROL operator panel • TTY Online interface with isolated receiver • SSI interface for absolute encoder connection • B&R Online interface • B&R MININET RS485 network capability Power & Environment • 24 VDC supply, 6.5 W consumption (without panel) • Certifications: CE, UL, HazLoc • Dimensions: 27.9 cm × 12.7 cm × 5.1 cm • Weight: 1.1 kg ## Key Features • Event counter and interrupt input capability • Reference input and positioning channels (A & B) • Optional relay expansion card (BRADREL1-0): 16 relay outputs, 3 A per output / 6 A per group, 240 VAC / 30 VDC switching • Sink-configured digital inputs with fast 2 msec response • Multi-range analog input conditioning ## Typical Applications Machine control, process automation, networked industrial systems, encoder-based positioning, and hazardous location installations requiring certified control architecture. ## Compatibility & Integration Functions within B&R automation ecosystems via MININET RS485 networking and integrates directly with MINICONTROL operator panels through dedicated PATA connectivity.
