Technical Evidence

VERIFIED FUNCTION AND NUMERIC DATA

The Siemens 6DD1660-0BH0 is a SIMATIC TDC CP52A0 Global Data Memory access module that connects compatible TDC systems through a high-speed fiber-optic communication link. One duplex-SC fiber interface transfers data at 640 Mbit/s using 8B/10B coding and CRC checksum verification. The module draws typical currents of 1.5 A at +5 V and 0.4 A at 3.3 V, dissipates approximately 9 W, and occupies one rack slot without requiring a fan. The 6DD1660-0BH0 supports deterministic data exchange and lifecycle replacement in demanding automation and drive-control installations.
