Siemens DDC PTM6.1PSI20-M-R Positioning Module Refurbished

The Siemens DDC PTM6.1PSI20-M-R is a refurbished positioning module that is specifically developed for Siemens DDC (Direct Digital Control) HVAC systems. The central DDC system sends control signals to the module that specify the desired location of a particular component. The PTM6.1PSI20-M-R precisely adjusts the position of a linked electric motor to accomplish the required result according to the signals it receives. This motor may operate dampers in the HVAC system to regulate airflow, water flow valves, or other moveable parts. A feedback mechanism is commonly incorporated into the module to confirm that the controlled component is positioned as intended and may use internal monitoring or sensors.
