Siemens 6DS1223-8AC Industrial Control Relay Assembly is an N‑AS interface module for the 20‑M local bus, part of the SM 1223 digital input/output family. It provides eight digital inputs (DI) and eight relay outputs (DQ), with the input side rated for 120/230 V AC. Built around the 6ES7223-1QH32-0XB0 core used in Siemens SM 1223 modules, it integrates into Siemens automation systems to connect AC sensors to the bus and drive loads through eight relay outputs for machine control and process interfacing.
