Siemens Simatic S7-1200 Relay output SM 1226, (W) 70mm, 5A Part number 6ES7226-6RA32-0XB0

Product Overview

The 6ES7226-6RA32-0XB0 is the “SM 1226 F-DQ 2× Relay Output” module — a digital output expansion module for the SIMATIC S7‑1200 PLC family. It provides two relay outputs suitable for signaling, switching loads, or safety-relevant control actions. The module supports fail-safe (PROFIsafe) configurations and meets safety standards up to Performance Level E (PL E) / SIL 3, making it suitable for safety-critical applications.

Key Features

• Relay-output module for SIMATIC S7-1200 (SM 1226)
• 2 relay outputs, each capable of switching up to 5 A
• Fail-safe capable (PROFIsafe) — suitable for safety circuits up to PL E / SIL 3
• Compact module width: 70 mm — saves space in control cabinets
• Output voltage range flexible: accepts 5 V … 30 V DC or 5 V … 250 V AC/DC depending on load
• LED indicators for output status diagnostics
• Mounting compatible with standard S7-1200 racks / backplane bus
