Siemens 6ES7146-6FF00-0AB0 SIMATIC ET 200eco PN F-DI 8/F-DQ 3 PROFIsafe Fail-safe Remote I/O Module

The Siemens 6ES7146-6FF00-0AB0 is a SIMATIC ET 200eco PN fail-safe I/O module with 8 safety digital inputs (24 V DC) and 3 safety digital outputs (24 V DC, 2 A), communicating via PROFIsafe over M12 PROFINET ports. It reaches Performance Level e per ISO 13849-1 and SIL 3 per IEC 61508, with IP65/67 protection and an eCoding plug-in connector.

Technical Specifications

Selection Notes

Eight safety digital inputs and three safety digital outputs on one module let a single ET 200eco PN station cover both an E-stop/guard-door input group and a safety-rated output group up to 2 A per channel, without a separate F-DQ module. Two-channel wiring on 4 of the 8 inputs plus PROFIsafe communication reach SIL 3 / PL e; using the inputs single-channel caps the achievable rating at SIL 2. The 60 degC max operating temperature and IP65/67 rating suit direct machine mounting outside a cabinet.

Applications

Fits machine safety circuits needing PROFIsafe-integrated E-stop, guard-door, or light-curtain inputs combined with safety-rated 24 V outputs up to PL e / SIL 3, in IP67 field-mount locations.
