Kinco K623-16DT is a discrete I/O expansion module for Kinco K6 series PLCs. It is used to increase the number of on-site input and output points in automation systems based on K6 controllers and is suitable for machines, dosing systems, conveyors, packaging equipment, pump stations, and other industrial applications. Within Kinco’s product transition table, the K6 family is presented as the successor to parts of the older K5 range, and K623-16DT is listed as the replacement for K523-16DT. (en.kinco.cn)
The K623-16DT provides 16 discrete channels in total: 8 digital inputs at 24 V DC and 8 digital transistor outputs at 24 V DC. K6 product references and third-party spec sheets consistently describe it as a hybrid DI/DO expansion module intended to expand the I/O capacity of the base CPU. (Nuicon)
