Siemens 6ES7334-0CE01-0AA0 Digital Input Module

Siemens 6ES7334-0CE01-0AA0 is the SIMATIC S7-300 SM 334 analog input/output module that provides 4 analog inputs and 2 analog outputs in a single 20‑pole front connector, designed for removal and insertion with the backplane bus in a SIMATIC S7-300 system. This non‑isolated module is powered by a 24 V DC supply and typically consumes about 3 W, with each channel offering 8‑bit resolution for AI and AO. The analog inputs tolerate up to 20 V on voltage inputs and up to 40 mA per channel for current inputs, and the module supports a cycle time of up to 5 ms across all channels. It is intended for use in SIMATIC S7-300 automation configurations that require four AI channels and two AO channels to sense and control analog signals.
