Module Overview
The ABB 07 EA 61 R1 (GJV3074351R1) is an 8-channel analog input module designed for high-precision process control systems. Each input converts 4–20 mA analog signals into digital binary values for processing by digital controllers.
Moreover, the module provides electrical isolation between analog channels, ensuring minimal interference and reliable signal acquisition even in electrically noisy environments. Channels 1–8 are monitored for open-circuit conditions using the ANAI or ANA11 function block.
In addition, its robust design allows seamless integration with ABB 907 PC 32 systems, enabling accurate and simultaneous monitoring of up to eight analog inputs.
