Siemens 6ES7134-4JB51-0AB0 PLC Module

Siemens 6ES7134-4JB51-0AB0 is an ET 200S analog electronics module that provides 2/4 RTD input channels for resistance-temperature detectors, designed for the ET 200S distributed I/O system and compatible with the 6ES7193-4CA50-0AA0 base. The module is 15 mm wide and offers 15-bit plus sign resolution per channel. It supports 2/4 AI RTD STD inputs, including Pt100 STD and Pt100 KL sensors, as well as Ni100 STD and Ni100 KL sensors, with RTD input ranges of 0–150 Ω, 0–300 Ω, and 0–600 Ω; it also accommodates 3- or 4-wire RTD connections and provides a cycle time of 110 ms per channel. An SF LED indicates a group fault, aiding diagnostics in complex installations. Typical applications include temperature monitoring and control in industrial processes such as furnaces and ovens where accurate RTD-based sensing is required; as a spare-part electronics module, it supports ET 200S deployments that rely on RTD inputs.
