Product Short Description
Product Description
The ABB SM811K01 (3BSE018173R1) is a high‑integrity safety CPU module kit designed for safety‑critical industrial automation applications. It is certified for SIL3 (Safety Integrity Level 3) compliance with IEC 61508 standards, making it suitable for the highest‑risk industrial processes. This module operates in conjunction with the ABB PM865 controller to form a 1oo2 (one‑out‑of‑two) diverse architecture, enabling robust safety functions for SIL1, SIL2, and SIL3 applications. The kit includes the SM811 safety module, TP868 baseplate, and TK852V10 synchronization link cable, and connects to the CEX bus via the BC810 interconnection box. It provides intelligent supervision of the main controller, executes safety‑related logic, and ensures fail‑safe operation in emergency scenarios. This module is intended for legacy system maintenance and upgrades; new installations should use the SM812K01 successor.
