Common-mode rejection sits at 90 dB minimum, crosstalk between inputs is held to −50 dB, and linearity error runs ±0.015 % of the input range — numbers that make the module a reasonable fit for four-wire RTD piping across a process skid rather than a high-speed lab role. ## Diagnostics and fault surfacing The module reports wire-break and short-circuit on the sensor side, raises a group error on the red SF LED, and pushes a diagnostic alarm plus a separate limit-value alarm to the host. Diagnostic information is readable by the CPU, so a field wire-break surfaces as an identifiable event rather than an open reading. ## Isolation map and field wiring Galvanic isolation is provided between the channels and the backplane bus, and between the channels and load voltage L+, but not between the channels themselves — so shield grounding strategy and any per-channel grounding have to be planned as a common return. Shielded cable runs are rated up to 500 m, which covers most distributed skid layouts without an intermediate repeater. ## Footprint, power, and backplane budget On the DIN rail the module occupies a 30 mm slice, stands 129 mm tall, and runs 136.5 mm deep at roughly 230 g — the standard ET 200S terminal-module pitch. From the backplane it draws 19 mA typical and up to 22 mA from L+, with a typical power loss of 0.4 W, leaving room in a standard ET 200S power budget for adjacent digital slices on the same station. ## Sourcing posture","metaTitle":"Siemens 6ES7134-7SD51-0AB0 AI 4×RTD, ET 200S","metaDescription":"Siemens 6ES7134-7SD51-0AB0 ET 200S analog input, 4 channels for Pt 100 / Ni 100 / resistance, integrating conversion, diagnostics.
