Siemens SIMATIC S7-1200 G2 SB 1231 6ES7231-4HD50-0XB0 Analog Input Signal Board 4AI 14-Bit 24V DC

Product Description

The Siemens 6ES7231-4HD50-0XB0 is a SIMATIC S7-1200 G2 SB 1231 analog input signal board designed to expand analog signal acquisition directly on compatible S7-1200 G2 controllers. It provides four analog input channels with 14-bit A/D conversion and supports selectable voltage ranges of ±10 V, ±5 V, and ±2.5 V, as well as 0–20 mA and 4–20 mA current signals. Operating from a 24 V DC supply, the compact signal board is well suited for connecting transmitters, sensors, and other analog field devices in machinery, process monitoring, and industrial automation applications.
