Siemens Analog Input / Output Module

Part Number: 6ES7234-4HE32-0XB0

Product Description:
6ES7234-4HE32-0XB0 is a SIMATIC S7-1200 SM1234 analog input/output module that combines 4 analog inputs and 2 analog outputs in a single expansion module. It supports voltage (±10 V) and current (0/4–20 mA) signals, enabling PLC systems to read analog sensors and control analog devices simultaneously.

Key Features

• 4 analog inputs + 2 analog outputs in one module

• Supports 0-10 V and 4-20 mA industrial signals

• 14-bit resolution for voltage signals and 13-bit for current

• Compact DIN-rail module for S7-1200 PLC expansion

• Ideal when both measurement and control signals are needed in the same module.

Typical Applications

• VFD speed control with 0-10 V / 4-20 mA output

• Reading pressure, flow, level transmitters

• Control of analog control valves

• Industrial process automation systems
