Specification

SEODescription

The Siemens 6XV1874-2B is a shielded PROFIBUS DP cable designed for robust industrial communication networks. It features a twisted-pair design with double-layer shielding (foil and braid) to ensure reliable data transmission in environments with high electromagnetic interference. This cable supports up to 32 nodes per segment and operates at PROFIBUS DP transmission rates up to 12 Mbps, with a maximum segment length of 100 meters at the highest speed. It is compatible with RS-485 interfaces and directly connects PROFIBUS DP devices, such as sensors, actuators, and PLCs, in a daisy-chain or bus topology. The 6XV1874-2B Cable operates within a voltage range of 30V DC and withstands temperatures from -30°C to +70°C, making it ideal for harsh industrial settings like manufacturing, automation, and process control. Key advantages include exceptional noise immunity, durability, and compliance with IEC 61158 standards. However, it requires proper grounding for optimal performance and may need repeaters for extended network spans.
