Siemens 6ES7134-6HD01-0BA1 Analog Input Module

The Siemens 6ES7134-6HD01-0BA1 analog input module provides 4 channels for the SIMATIC ET 200SP distributed I/O system, enabling precise acquisition of analog signals from sensors and field devices in process automation plants, manufacturing lines, and industrial control panels. It supports voltage inputs (±10 V) and current inputs (0/4–20 mA) with 16‑bit resolution and typical accuracy of ±0.3%. Conversion per channel occurs in approximately 0.5–1 ms, and the unit operates from a 24 V DC supply with a current draw of about 50–60 mA. Diagnostics include wire break, overflow, and underflow detection, while channel-to-channel and backplane isolation help protect the system integrity. Mounting is on a DIN rail using BaseUnit BU type A0, with dimensions of 73 × 15 × 58 mm and a weight of about 0.04 kg. Commonly used for replacement, retrofit, and analog input expansion, this module fits industrial automation applications such as process monitoring, temperature and pressure sensing, and lineup control in production environments. It is compatible with the SIMATIC ET 200SP family, and Siemens lists common replacements including 6ES7134-6HD00-0BA1 and 6ES7134-6JD00-0CA1.
