The 1786-TPS ALLEN-BRADLEY ControlNet tap is a vital component for constructing reliable, high-speed deterministic networks in industrial automation. Designed by Rockwell Automation, this tap enables physical network segmentation without signal degradation, supporting up to 48 nodes per segment. It features a rugged metal housing rated for IP20, ensuring durability in demanding environments from -25°C to +70°C. The tap uses standard BNC connectors for trunk cable attachment and includes a built-in terminator for proper line impedance. Its passive design requires no external power, making it maintenance-free and ideal for critical applications in process control, safety systems, and discrete manufacturing. The 1786-TPS is fully compliant with ControlNet specifications and is shipped factory-sealed with global stock availability.
