Siemens 6ES7526-1BH00-0AB0 SIMATIC ET 200MP F-DI 16x24VDC PROFIsafe SIL3 Fail-safe PLC I/O Module

The Siemens 6ES7526-1BH00-0AB0 is a SIMATIC ET 200MP fail-safe digital input module (F-DI 16x24VDC PROFIsafe) with sixteen 24 V DC safety inputs rated up to Performance Level e per ISO 13849-1 and SIL 3 per IEC 61508. It mounts on the ET 200MP backplane in a 35 mm module width and carries safety data over PROFIsafe into the F-CPU's safety program.

Technical Specifications

Certifications & Standards

• ISO 13849-1 PLe
• IEC 61508 SIL 3

Selection Notes

16 fail-safe channels on one 35 mm module cover a full safety zone (E-stops, guard doors, light curtains) without stacking multiple smaller F-DI modules, which keeps the ET 200MP rack shorter and cuts engineering points. The PLe / SIL 3 rating and PFH below 1.00E-09 1/h qualify it for the highest safety category most machine-safety applications require, so pick a lower-channel-count F-DI variant only when the panel has fewer safety signals to save rack width.

Applications

Wiring emergency-stop circuits, safety door interlocks, light curtains, and two-hand controls into a SIMATIC S7-1500 / ET 200MP safety program over PROFIsafe, in machine safety and process-safety installations that require SIL 3 / PLe certification.
