Siemens 6ES7146-6HF00-0BB0 SIMATIC ET 200eco PN AI 6xU/I+AIQ 2xU/I IP69K Remote I/O Module

The Siemens 6ES7146-6HF00-0BB0 is a SIMATIC ET 200eco PN module with 6 fixed analog inputs plus 2 configurable analog input/output (AIQ) channels for voltage or current signals, on M12-L PROFINET ports. It offers 16-bit resolution, MRP and S2 system redundancy, shared device across 2 PROFINET controllers, and IP67/IP69K protection for washdown environments.

Technical Specifications

Selection Notes

Two of the eight analog channels, the AIQ pair, are software-parameterized as either inputs or outputs, so the same module can be configured as 6 AI + 2 AO or 8 AI depending on the station's I/O mix, without swapping hardware. S2 system redundancy and shared-device operation across 2 controllers keep the module reachable through a controller failover, and the integrated 2-port switch supports line or ring PROFINET topologies. IP67/IP69K protection extends to washdown duty.

Applications

Fits mixed analog I/O points on a washdown-rated PROFINET line where channel count or signal direction may need to change without adding hardware, and where S2 redundancy is required for uptime.
