Siemens 6ES7145-4FF00-0AB0 SIMATIC ET 200pro EM 4AO-U HF Remote I/O Module

The Siemens 6ES7145-4FF00-0AB0 is a SIMATIC ET 200pro EM 4AO-U HF electronic module with 4 voltage analog outputs (0-10 V, 1-5 V, or -10 V to +10 V), 15-bit resolution, and per-channel short-circuit protection. It runs from a 24 V DC supply, draws 65 mA rated current, and needs the connection module IO 6ES7194-4..00-0AA0, sold as a separate line item, to complete an ET 200pro station.

Technical Specifications

Selection Notes

15-bit resolution on the -10 V to +10 V and 0-10 V ranges (14-bit on 1-5 V) gives finer output steps than a standard-feature analog module, useful for closed-loop setpoint outputs that need tight linearity. Per-channel electronic short-circuit protection to chassis lets one shorted output be cleared without taking down the other three channels. Connecting it into an ET 200pro station additionally requires the IO connection module 6ES7194-4..00-0AA0, sold as a separate line item.

Applications

Fits closed-loop analog setpoint outputs at -10 to +10 V, 0-10 V, or 1-5 V for valve positioners, drive references, or process control loops on an ET 200pro station.
