Siemens 6ES7526-2BF00-0AB0 SIMATIC S7-1500 F-DQ 8x24VDC/2A PPM Fail-safe PLC I/O Module

The Siemens 6ES7526-2BF00-0AB0 is a SIMATIC S7-1500 fail-safe digital output module with 8 channels rated 24 VDC at 2 A per channel, using PROFIsafe (PPM) over PROFINET or PROFIBUS. It reaches PL e per ISO 13849-1 and SIL 3 per IEC 61508, with a PFH below 2.00E-09 1/h for safety-related output switching.

Technical Specifications

Selection Notes

The 2 A per-channel rating and PL e / SIL 3 classification make this a main safety-output module for switching contactor coils or safety valves directly, rather than only pilot-level loads. PROFIsafe over the existing PROFINET or PROFIBUS network carries the safety telegram without separate safety wiring back to the F-CPU, which cuts cabinet wiring versus a hardwired safety relay approach. The 35 mm module width and 0-40 °C vertical-install ceiling are worth checking against enclosure layout and cooling before specifying a dense safety I/O rack.

Applications

Safety-related digital output switching for emergency-stop circuits, guard-door interlocks, and safety valve control in machines with an F-CPU and PROFIsafe network.
