At a Glance

Brand	Siemens
Model	6ES7334-0CE01-0AA0
Product Type	SM 334 analog I/O module
Core Function	Analog signal acquisition and output
Application	SIMATIC S7-300 and ET 200M stations

Mixed analog channels

Four analog inputs and two analog outputs in one module.

Voltage and current

Use 0–10 V or 0–20 mA signal ranges.

Active backplane

Removal and insertion are possible with an active backplane bus.

Product Overview

6ES7334-0CE01-0AA0 combines four analog inputs and two analog outputs in the SIMATIC S7-300 SM 334 module for compact voltage and current signal handling.

Inputs and outputs provide 8-bit resolution including overrange, with a maximum input cycle time of 5 ms and a 20-pin front connection.

Ordering focus: Match the voltage or current wiring, output load and 20-pin connector, and use the active-backplane arrangement required for removal and insertion.

Key Functions

Mixed-signal processing

The four inputs and two outputs support 0–10 V and 0–20 mA signals in a single non-isolated module.

Transducer interfacing

Voltage sensors and four-wire current transducers can be connected, while two-wire current transducers are not supported.

Controlled analog output

Voltage outputs include short-circuit protection, and the analog output conversion time is 500 µs per channel.

Frequently Asked Questions

Can I connect voltage and current instruments to 6ES7334-0CE01-0AA0?

The analog channels support 0–10 V and 0–20 mA signal ranges.

Does 6ES7334-0CE01-0AA0 support Voltage and current for mobile equipment?

Thermocouple, resistance thermometer and resistance measurement are not supported by this version.

Can I use a two-wire current transmitter with 6ES7334-0CE01-0AA0?

Current measurement supports four-wire transducers rather than two-wire transducers.

Which front connector should I order for 6ES7334-0CE01-0AA0?

A 20-pin S7-300 front connector is required.

What output load can I connect to 6ES7334-0CE01-0AA0?

Voltage loads must be at least 5 kΩ and current loads must not exceed 300 Ω.

Can I exchange 6ES7334-0CE01-0AA0 without interrupting the active backplane?

Removal and insertion are possible when the station uses an active backplane bus.

Will 6ES7334-0CE01-0AA0 generate diagnostic interrupts for channel faults?

This module provides neither alarms nor a diagnostic function.

Compatibility & Ordering Notes

Before ordering 6ES7334-0CE01-0AA0: Use this non-isolated SM 334 version with the intended voltage or current instruments, the correct front connector and a station arrangement suitable for the required replacement procedure.

Compatibility Checklist for 6ES7334-0CE01-0AA0

• Keep this 8-bit 0CE01 version distinct from the 12-bit 0KE00 temperature-capable module.
• Provide four-wire current transducers where current measurement is required.
• Check the voltage and current output load limits before connecting actuators.
• Use an active backplane if removal and insertion during station operation is required.
