SIEMENS 6ES7136-6BA01-0CA0 SIMATIC DP Fail-Safe Digital Input Module for ET 200SP, 8 Inputs, 24 V DC, SIL 3, PL E, HF

The SIEMENS 6ES7136-6BA01-0CA0 is a fail-safe digital input module from the SIMATIC DP series, designed for the ET 200SP distributed I/O system. This high-feature (HF) module provides 8 fail-safe digital inputs with 24 V DC supply, supporting safety applications up to SIL 3 (IEC 61508) and PL E (ISO 13849) with Category 4. It features 1-wire connection technology, comprehensive diagnostics (short circuit, wire break, supply voltage monitoring), and parameterization via TIA Portal. The module is DIN rail mountable, has IP20 protection, and operates in a temperature range of 0 °C to 60 °C (horizontal) or 0 °C to 50 °C (vertical). It is certified with CE, UL, cULus, ATEX, FM, KC, RCM, and EAC.
