Product Description

The SIEMENS S7-300 Analog Module 6ES7331-7PF01-0AB0 is an 8-Channel AI Module designed for precise measurement of current or voltage signals in industrial automation systems. It supports current inputs (4-20 mA, 0-20 mA) and voltage inputs (±10 V, 0-10 V), with a 16-bit resolution ensuring high accuracy. Directly integrated into the S7-300 PLC rack via the backplane bus, it operates on 24 V DC with a working temperature range of 0°C to 60°C. Ideal for manufacturing, process control, and energy industries, this Current/Voltage Input Module offers robust noise immunity and flexible configuration via STEP 7 software. Its compact design saves space, though it lacks HART protocol support and requires external shielding for extremely noisy environments. Battery, screen, and detection distance specifications are not applicable to this module.
