It bridges two PROFIBUS DP segments at up to 12 Mbit/s, supporting up to 31 DP slaves per segment, or 64 when using RS 485 repeaters or optical link modules. The active terminating resistor on the lower-level DP master system eliminates the need for external termination. ## Wide temperature range and environmental resilience The conformal coating and compliance with ANSI/ISA-71.04 Level GX Group A/B (excluding trichlorethylene) and EN 60721-3-3 class 3C4 means it tolerates harmful gas concentrations and salt spray that would corrode uncoated boards within months. This is the variant to specify when the panel sits near a chemical process or coastal environment. Power is drawn from the S7-400 bus module, so no separate supply wiring is needed — the coupler presents a single slot load on the rack. No stock-holding claim; each order is verified against the BOM quantity. Dimensions are 125 mm high, 40 mm wide, 130 mm deep — occupies one standard S7-400 slot width. IP20 rated, so it is intended for a closed control cabinet; the conformal coating handles the internal atmosphere, but the housing itself is not sealed against liquid ingress.","metaTitle":"Siemens 6AG1197-1LB00-4XA0 SIPLUS S7-400 Y Coupler","metaDescription":"Siemens 6AG1197-1LB00-4XA0 SIPLUS S7-400 Y coupler with conformal coating.
