Siemens 6ES7134-4FB00-0AB0 IO Module For S7-300

Siemens 6ES7134-4FB00-0AB0 is a two-channel analog input module for the ET 200S distributed I/O system used with S7-300 and PROFIBUS-DP networks. The 15 mm‑wide AI U high‑feature module provides two analog input channels with ranges described as +/-10 V and +/-5 V, including a 13‑bit + sign for +/-5 V and 12‑bit + sign for 1..5 V, and a per‑channel conversion cycle time of about 65 ms with an SF (group fault) LED for diagnostics. As part of the ET 200S family, it communicates with the PLC over the DP network and is configured for use in distributed I/O installations that require precise analog measurements and fault indication. Siemens lists this model as no longer available.
