Siemens 6ES7136-6BA01-0CA0 SIMATIC ET 200SP F-DI 8x24VDC HF PLe SIL3 Fail-safe I/O Module

The Siemens 6ES7136-6BA01-0CA0 is a SIMATIC ET 200SP fail-safe digital input module (F-DI 8x24VDC HF) with 8 channels, rated Performance Level e / Category 4 per ISO 13849-1 and SIL 3 per IEC 61508. It is 15 mm wide, mounts on BU type A0, and includes an integrated 24 V encoder supply across all 8 channels.

Selection Notes

The PLe/Category 4 and SIL 3 ratings cover the input stage of most machine safety functions -- e-stop chains, guard-door interlocks, light-curtain inputs -- without needing a higher-rated module. A PFH below 1.00E-09 1/h leaves headroom in the overall SIL 3 loop budget when this module is combined with a safety logic controller and output stage. The 800 mA total encoder-supply current across 8 channels sizes it for standard 24 V interlock switches and E-stop buttons without an external supply; a module with lower per-channel current would need one.

Applications

Emergency-stop circuits, safety guard-door monitoring, and light-curtain or two-hand control inputs wired into a SIMATIC ET 200SP fail-safe station.
