Siemens 6ES7 334-0CE01-0AA0 Analog Output Module

Siemens 6ES7334-0CE01-0AA0 is a SIMATIC SM 334 analog input/output module for the SIMATIC S7-300 family, delivering 4 analog inputs and 2 analog outputs on a single non-isolated card that plugs into the backplane via a 20‑pin interface and supports removal and insertion with the backplane bus. The input channels can be wired for either 0–10 V or 0–20 mA measurement, while the output channels can be wired to deliver 0–10 V or 0–20 mA, enabling mixed signal handling on one module. The device is designed for operation in ambient temperatures from 0°C to +60°C (climatic class T5). This SM 334 module is part of Siemens’ analog I/O family and is commonly used for compact automation tasks, including process control and instrumentation, where four inputs and two outputs are required in a single card, with non‑isolated I/O tied directly to the S7‑300 backplane.
