Siemens 6ES7136-6AA00-0CA1 Analog Input Module ET 200SP

Siemens 6ES7136-6AA00-0CA1 is a four-channel fail-safe analog input module (F-AI) for the SIMATIC ET 200SP distributed I/O system, designed to accept four current inputs in the 0(4) to 20 mA range. This HF (fail-safe) module mounts on the ET 200SP base unit and operates on the SIMATIC DP network, supporting both 2-wire and 4-wire sensors. It provides safety-rated input channels up to Performance Level e (ISO 13849-1) and up to SIL 3 (IEC 61508), making it suitable for safety-critical measurement tasks in industrial automation where reliable current-signal acquisition is essential. The 6ES7136-6AA00-0CA1 designation places it within Siemens' ET 200SP fail-safe I/O family, enabling integration of analog current signals into safety-related control schemes and enabling monitoring of process variables such as transmitter output and loop current in industrial processes. As part of the DP-based ET 200SP ecosystem, it aligns with Siemens' safety-instrumented architecture and can be combined with other fail-safe modules to implement comprehensive safety functions.
