Siemens 6ES7134-6HB00-0CA1 SIMATIC ET 200SP AI 2xU/I 2-/4-Wire HF 16-Bit Remote I/O Module

The Siemens 6ES7134-6HB00-0CA1 is a SIMATIC ET 200SP analog input module with 2 differential channels configurable for voltage or current measurement, 16-bit resolution including sign, and a 0.1% operational error limit across the full temperature range. It mounts on BaseUnit type A0 or A1 with color code CC03, runs from a 24 V DC supply, and supports isochronous mode down to 250 microseconds for synchronized measurement cycles.

Technical Specifications

Selection Notes

The 4-wire connection option eliminates lead-resistance error for precision current-loop measurement, while the 2-wire mode keeps wiring simple for standard transmitters up to a 650 ohm burden. The HF designation reflects the wide integration-time range down to 0.625 ms and isochronous support to 250 microseconds, so pick this module over a standard-feature analog input when the application needs fast synchronized sampling or the tighter 0.05% base accuracy at 25C.

Applications

Motion-synchronized process measurement on PROFINET isochronous real-time segments, distributed analog I/O for ET 200SP stations on PROFINET or PROFIBUS, and sensor integration in machine-builder control panels where both 2-wire and 4-wire transmitters are in use.
