Product Overview
6ES7231-0HC22-0XA0 is a SIMATIC S7-200 analog input module (EM 231) designed exclusively for S7-22X CPUs. It provides 4 differential analog inputs with 12-bit conversion covering voltage (0-10 V, ±5 V, ±2.5 V) and current (0-20 mA) ranges. Its function is to convert field analog signals into digital process values for control systems. Common applications include small-scale process control, sensor integration, and retrofit in existing S7-200 installations.
