Siemens Simatic ET 200SP, Analog input module, 4-wire, 16 bit Part number 6ES7134-6HB00-0CA1

Product Overview

The 6ES7134-6HB00-0CA1 is an analog input module from the SIMATIC ET 200SP distributed I/O family. It provides two analog input channels capable of measuring voltage or current in either 2-wire or 4-wire configurations. The module is a “High Feature (HF)” variant, offering high accuracy and diagnostic capabilities, making it suitable for precise analog measurement tasks in automation, process control or monitoring applications.

Key Features

• Analog input module — 2 channels for voltage or current signals
• Supports 2-wire or 4-wire wiring depending on sensor type
• High-feature version: enhanced accuracy (typical ±0.1 %) and channel diagnosis
• Resolution: 16-bit — good precision for analog measurements
• Compatible with ET 200SP base units (BU type A0 or A1)
• Compact module width — saves panel space when building I/O racks
• Supports common analog signal ranges (voltage and current) for flexibility
• DIN-rail or rack mounting via standard ET 200SP backplane bus

Applications

This analog input module is ideal for feeding analog sensor data (e.g. 0–10 V, 4–20 mA, thermocouples/transducers if wired appropriately) into a distributed I/O system. Use cases include process control, measurement systems, temperature/pressure monitoring, remote sensor integration, data logging, and industrial automation systems requiring accurate analog signal input. It is especially useful where modular expansion and compact I/O racks are required, such as decentralized control cabinets, machine tools, or factory automation panels.
