20 mm slice, BU D0 — what it fits
The 6ES7134-6PA01-0BD0 is a 20 mm wide analog input module for the Siemens ET 200SP distributed I/O system. It requires a BU type D0 base unit (the dark-colored one) — the module won't seat in a BU type A0 or B0. Depth is 58 mm, so it sits flush in a standard ET 200SP assembly with no overhang past the base unit. Mounting position is unrestricted.
Voltage, current, power — one module covers the three-phase panel
This module measures voltage, current, active power, reactive power, frequency, and energy in a single slice — no separate transducer needed. It accepts 100-240 V AC on the measurement input and is designed for sinusoidal or distorted waveforms. The power supply is drawn from the voltage measurement channel, so no separate auxiliary feed is required. Zero point suppression is parameterizable from 20 to 250 mA (default 50 mA) — useful for ignoring idle current on lightly loaded feeders. Diagnostic and channel alarms are supported, with a green/red DIAG LED and a red Fn LED per channel. Firmware is V3.0.
