Turck BL20-S4T-SBCS | Base Module for BL20 I/O System, 4-Wire Tension Clamp, C-Rail Access

The BL20-S4T-SBCS (Ident-No: 6827063) is a passive wiring base that supports the modular "slice" architecture of the BL20 system. This specific model is distinguished by its 4-tier (S4) wiring arrangement and C-Rail (SBCS) access. The C-rail connection allows the field-side shield or ground to be connected directly to the DIN rail, providing a convenient path for electromagnetic interference (EMI) protection without additional wiring.
