SIEMENS 6ES7138-4FB03-0AB0 Simatic S7 PROFIsafe module

Buy online your SIEMENS 6ES7138-4FB03-0AB0 Simatic S7 PROFIsafe module from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

The Siemens SIMATIC ET200S 4 F-DO PROFIsafe is a safety digital output module designed for ET200S distributed I/O systems used in industrial automation applications. It provides safe control of actuators such as contactors, safety relays, solenoid valves, and emergency stop circuits while meeting the highest functional safety requirements.

The module features 4 fail-safe digital outputs (F-DO) operating at 24 V DC with a maximum output current of 2 A per channel. With an overall width of just 30 mm, it offers a compact solution for space-saving installation within ET200S stations and control cabinets.

Using PROFIsafe technology, the module enables secure communication over industrial networks and can be integrated into PROFINET systems when used with an IM 151-3 HF interface module. This flexibility makes it suitable for both existing and modern automation architectures.

The module supports safety applications up to Category 4 (EN 954-1), SIL 3 (IEC 61508), and Performance Level e (PL e) according to ISO 13849-1, making it ideal for safety-critical processes where personnel and machine protection are essential.

Common applications include CNC machine tools, automated production lines, material handling systems, robotic cells, and industrial machinery requiring advanced safety functions. As a replacement or spare part, the SIMATIC ET200S 4 F-DO PROFIsafe module provides a reliable solution for restoring and maintaining the original safety performance of industrial automation systems.

Frequently asked questions about 6ES7138-4FB03-0AB0:

Which systems can this module be used with?
It is used within SIMATIC S7 safety installations, typically in ET 200 distributed I/O stations that support PROFIsafe. It works with S7 F-CPUs configured for safety applications.

Does it run on PROFIBUS or PROFINET?
The PROFIsafe layer is supported over either transport. The actual bus depends on the selected ET 200 station interface module, while this safety module handles the PROFIsafe function and diagnostics.

What should I consider when replacing a failed unit?
Match the exact 6ES7138-4FB03-0AB0 reference, retain the project parameters, and verify safety signatures in your engineering software. After installation, confirm diagnostics and safe-state behavior during commissioning checks.
