Product Description P/N: 6ES7138-4FA05-0AB0
Description
The Siemens 6ES7138-4FA05-0AB0 is a fail-safe digital input module for the SIMATIC ET 200S distributed I/O system, designed for PROFIsafe communication over PROFIBUS or PROFINET networks. It provides 4/8 safety-rated digital inputs for monitoring emergency-stop devices, safety switches, light curtains, and other protective equipment in functional safety applications. With a safety integrity rating up to PL e (ISO 13849-1) and SIL 2/3 (IEC 61508), the module is widely used in machine safety, factory automation, and high-risk industrial environments where reliable personnel protection is required.

Information About 6ES7138-4FA05-0AB0
The 6ES7138-4FA05-0AB0 belongs to the ET 200S F-I/O family and offers both single-channel (8 inputs) and dual-channel (4 inputs) operating modes to support safety architectures up to Category 4 / PL e. Operating at 24 VDC, it supports parameterizable input filters, diagnostic alarms, and integrated short-circuit detection. The module communicates via PROFIsafe and is compatible with both DP (PROFIBUS) and PN (PROFINET) configurations when used with IM151-3 HF. With a slim 30 mm width, it saves cabinet space while providing full functional safety compliance. The digital inputs feature fast response times, long cable support up to 500 m, and green/red diagnostic LEDs for quick maintenance. Designed for harsh industrial environments, it carries global certifications and supports comprehensive diagnostic reporting through STEP 7 and TIA Portal.
Key Features:
- Fail-Safe Input Module: Supports 4 dual-channel or 8 single-channel safety inputs for machinery protection.
- Highest Safety Ratings: Meets PL e, SIL 2 (single-channel), SIL 3 (dual-channel) safety levels.
- PROFIsafe Over DP/PN: Fully compatible with PROFIBUS DP and PROFINET using IM151-3 HF.
- 24 VDC Operation: Designed for standard industrial control voltage with short-circuit monitoring.
- Advanced Diagnostics: Built-in alarms, readable diagnostics, and fault indication LEDs.
- Parameterizable Filters: Adjustable input delay (0.3–17 ms) for noise-immune operation.
- Slim 30 mm Design: Space-efficient ET 200S form factor.
- Long Cable Support: Up to 500 m with shielded or unshielded wiring.
- Robust Industrial Compliance: Certified to EN/IEC safety standards and PROFIsafe requirements.
- Flexible Sensor Support: Compatible with 2-wire sensors within current limits.
The 6ES7138-4FA05-0AB0 delivers high-integrity safety input capabilities for reliable machine protection in distributed ET 200S systems.
