The Siemens 6ES7134-6PA00-0BD0 is an ET 200SP analog input module dedicated to energy measurement — voltage, current, active/reactive power, and energy in a single 20 mm slice. It feeds on 100-240 V AC directly from the measured line (L1), eliminating a separate power supply. Mounted on a BU type D0 base unit, it fits any ET 200SP station.
What it measures and how you set it up
This module handles sinusoidal or distorted voltage curves and accepts current via an external CT (0.5 A secondary). It reports active power, reactive power, energy, frequency, and voltage — all cyclically and acyclically. Zero-point suppression is parameterizable from 20 to 250 mA (default 50 mA), useful for ignoring idle current on lightly loaded feeders. Firmware V2.0 supports I&M data records 0 through 3. Diagnostic alarms come standard; the green/red DIAG LED and red Fn LED per channel give quick fault isolation. No hardware interrupt or isochronous mode, but for standard sub-second energy monitoring that's not a gap. Mechanical coding on the module prevents plugging into the wrong base unit.
