Product description

The Siemens 6ES7231-4HF32-0XB0 is a SIMATIC S7-1200 analog input signal module (SM 1231) equipped with 8 analog inputs. It supports the same versatile input ranges as its 4-channel counterpart: +/-10 V, +/-5 V, +/-2.5 V for voltage, and 0-20 mA or 4-20 mA for current, all with a 12-bit plus sign resolution (13-bit ADC).

This module is designed for applications requiring a higher density of analog input signals, such as complex process control, large-scale automation projects, and multi-point monitoring in industries like chemical processing, water treatment, and manufacturing.

Stanlo Automation, a proud veteran-owned business, offers the Siemens 6ES7231-4HF32-0XB0 as part of our extensive inventory of surplus industrial automation components. Trust us for quality, reliability, and cost-effective solutions to meet your automation needs.
