Siemens 505-7028 8-Point Input Module

Siemens PPX:505-7028 is an 8-channel analog input module that provides eight thermocouple inputs for the TI505 programmable logic controller. Specifically designed for TI505 systems, it allows direct temperature sensing at up to eight points in a process and feeds those readings into the TI505 CPU for monitoring and control. As part of the Siemens 505 family of I/O modules, the 505-7028 expands temperature measurement capabilities in legacy automation installations, and the module is commonly referenced by the part number 505-7028 or PPX:505-7028. Typical applications include process temperature monitoring in manufacturing, energy management, and environmental or climate-control scenarios where multiple temperature points require dedicated thermocouple inputs, enabling real-time data collection and integration with TI505 logic or scaling routines. This 8-channel module is used in conjunction with other TI505 I/O modules to build compact temperature-monitoring subsystems in older Siemens automation setups.
