Product Overview
The ABB SM811K01 is a high-integrity safety CPU module designed for ABB’s System 800xA platform. It works with the PM865 controller to provide SIL2/SIL3-compliant digital I/O and safety supervision for critical industrial applications.
This module supports 3 safety-related digital inputs and 2 safety outputs, forming a 1oo2 diverse architecture with the PM865 for high reliability. Its 32 MB RAM and robust design ensure fast response times and fault tolerance. SM811K01 connects via the CEX bus using the BC810 interconnection box and supports synchronization through the TK852V10 cable.
The module operates at 24 VDC ±10%, consumes 5 W typical (7 W max), and withstands harsh conditions with an operating range of –25°C to +70°C. It features RS-485 communication, overvoltage monitoring, and isolation up to 1500 V AC between inputs and outputs.
