The SIPLUS S7-1200 SM 1223 16DI/16DQ (model number: 6AG1223-1BL32-4XB0) is a high-density digital input/output module manufactured by Siemens, designed for the S7-1200 series controllers. This module is built upon the base model 6ES7223-1BL32-0XB0 and is protected with a conformal coating for reliable operation in extreme environmental conditions. It can operate stably within a temperature range of -20°C to +60°C. The module features 16 digital input (DI) and 16 digital output (DQ) channels. The digital inputs operate at 24 V DC and support both sink and source connection types. The digital outputs are transistor-based and can control a current of up to 0.5 A per output channel. This module is well-suited for industrial automation applications requiring the reading of a large number of digital signals (e.g., states of various buttons, switches, sensors) and controlling actuators (e.g., relays, solenoids, indicators). The module has a net weight of 0.310 kg and packaging dimensions of 9.00 x 10.90 x 8.60 cm.\n
