The TURCK BLCEN-4M12MT-4AI4AO-VI is a compact fieldbus I/O station for Industrial Ethernet distributed I/O, delivering four analog inputs and four analog outputs to acquire and control signals over EtherNet/IP, PROFINET, and Modbus TCP. Designed for machine-mounted use without a control cabinet, it serves process skids, water treatment, packaging equipment, chemical processing systems, and automated manufacturing lines, with IP67/IP69K protection to withstand harsh environments. As a member of TURCK's BL Compact series, this device provides 4 AI/4 AO with input types of 0/4-20 mA and -10/0/+10 VDC, and output types of -10/0/+10 VDC, both at 16-bit resolution, plus two M12 D-coded Ethernet ports (10/100 Mbps) and an integrated Ethernet switch, all powered from 24 VDC and housed in glass-filled nylon with nickel-plated brass connectors. It uses galvanic isolation via optocouplers and offers dual rotary switches for node addressing with LED diagnostics for channel status; dimensions 113 × 71 × 32.5 mm and weight approximately 390 g, capable of operating from -40°C to +70°C. Common replacements include TURCK TBEN-L4-4AI4AO-VI, BL67-4AI4AO-VI, and BLCEC-4M12MT-4AI4AO-VI.
