Bus Termination SINEC L2 & PROFIBUS RS485 Compatible Wide Supply Voltage Range Ensures Signal Integrity For Last Device on Bus

Product description

The Siemens 3UF1900-1KA00 is a bus termination module designed for the SINEC L2-RS485 and PROFIBUS RS485 communication protocols. Its primary function is to terminate the bus line after the last device, ensuring signal integrity and reliable data communication in industrial networks. This module supports a wide range of supply voltages, including 24 V AC, 110/115/120/220/230/240 V AC, and 380/400/415 V AC.

This termination module is critical for maintaining stable and error-free communication in distributed control systems, SCADA systems, and automated manufacturing lines. It plays a vital role in preventing signal reflections and ensuring that data packets are correctly transmitted across the bus.

Stanlo Automation, a veteran-owned provider of industrial automation surplus, offers the Siemens 3UF1900-1KA00. We recognize the importance of reliable network infrastructure and provide this essential component to ensure the robust performance of your industrial communication systems.
