Siemens 6AG1136-6BA01-2CA0 Fail-Safe Digital Input Module

Siemens SIPLUS ET 200SP F-DI 4/8x24 V DC HF, 6AG1136-6BA01-2CA0, is a fail-safe digital input module for the ET 200SP distributed I/O system. Built on the 6ES7136-6BA01-0CA0 core with conformal coating, it provides eight 24 V DC digital input channels designed for safety-related automation tasks in harsh environments, with fail-safe performance up to PL e (ISO 13849-1) and SIL3 (IEC 61508). The module supports a wide operating temperature range of -40 to +60 °C, making it suitable for industrial installations subject to temperature fluctuations. It is configurable via STEP 7 and supports RUN-time reparameterization within the ET 200SP fail-safe family, enabling integration of safety signals into Siemens automation projects. Typical applications include safety interlocks, emergency-stop monitoring, and other safety-critical digital inputs in machinery and production lines, where certified safety performance and Siemens interoperability are essential.
