What it is and what it does
The 6ES7134-4FB00-0AB0 is a Siemens ET 200S 2-channel analog input module for voltage signals. It measures ±5 V, 1 to 5 V, or ±10 V using an integrating measurement principle, and each channel is parameterizable for digital filtering in four stages. Rated voltage of 24 V DC is supplied from the backplane bus; power loss is 0.6 W typical. The module is 15 mm wide, 81 mm high, and 52 mm deep, fitting a single ET 200S slot. Conversion time per channel is 65 ms (55/65 ms variants), and integration time is parameterizable at 16,7 or 20 ms. Isolation is tested at 500 V DC between channels and backplane bus.
Signal integrity and diagnostics
For clean signals in a noisy plant, each channel requires shielded cable; maximum cable run is 200 m. Wire-break detection is enabled only in the 1 to 5 V range. Group diagnostics (SF red LED) and per-channel overflow/underflow can be enabled or disabled. No isochronous mode (no equidistant cycle), so the module suits standard ET 200S applications rather than synchronized motion.
