Siemens 6ES7526-2BF00-0AB0 Digital Input Output Module

Siemens 6ES7526-2BF00-0AB0 is a fail-safe digital output module (F-DQ) for SIMATIC S7-1500 and ET 200MP I/O networks. It provides eight 24 V DC outputs rated at 2 A per channel, in a 35 mm-wide module designed for compact panel installations. This PROFIsafe variant delivers safety-related outputs with certified performance up to PL E (ISO 13849-1) and SIL3 (IEC 61508), making it suitable for safety-critical tasks such as energizing relays, interlocks, and other safety devices while preserving standard 24 V control logic. With eight independent channels, the card supports scalable safety signaling in a single module and helps simplify wiring and diagnostics in integrated automation layouts. The F-DQ designation identifies the fail-safe digital output function within Siemens' ET 200MP ecosystem, enabling seamless integration with other S7-1500 I/O modules in a unified safety architecture.
