What it is and what it does
The Siemens 6ES7134-6HB00-0DA1 is a 2‑channel analog input module for the SIMATIC ET 200SP distributed I/O system. It handles voltage (±10 V, 1–5 V, 0–10 V) and current (0–20 mA, 4–20 mA, ±20 mA) ranges with resolutions from 13 to 16 bits including sign. Oversampling delivers a minimum resolution of 50 µs per channel, letting it capture fast transients on two channels simultaneously.
Sourcing and lifecycle
This module is listed as current production. Lead time is subject to Siemens allocation; we quote it to order against a BOM line with blanket-pricing options for volume builds.
Mechanical fit and wiring
It mounts in BU type A0 or A1 base units (ordered separately). Base unit choice decides the wiring connection — 2‑wire or 4‑wire — and provides the 24 V supply needed for current measurement. At 15 mm wide, it takes up less DIN rail space than a standard 20 mm module.
Diagnostics and signal conditioning
Channel‑by‑channel alarms detect wire‑break (4–20 mA only), short‑circuit (voltage or current encoder supply), overflow, and underflow. A group error signal triggers on any fault. Isochronous mode supports precise time‑stamped data, and I&M data (I&M0 to I&M3) provides module identification and maintenance records.
