TM173

The TM173 is a compact logic controller designed for driving industrial utility applications, HVAC equipment, and small machines requiring reliable control, simple programming, and fast integration. It provides a robust solution for lightweight automation architectures, relying on efficient logic processing, integrated inputs/outputs, and standardized industrial communication. The TM173 is particularly suited for standalone units, secondary process machines, transfer systems, thermal regulation modules, and distributed control stations. Equipped with onboard I/O, it can directly manage sensors, actuators, simple motors, and control devices. Its digital and analog inputs ensure local processing of signals such as position sensors, pressure switches, temperature probes (PT100/PT1000 depending on configuration), or flow sensors. The outputs drive valves, relays, single‑phase motors, or external control modules. This integrated configuration reduces wiring, simplifies commissioning, and ensures high reliability for repetitive operations. The TM173 offers several programmable operating modes to manage sequences, timing functions, repetitive cycles, simple regulation loops, or alarm logic. Its intuitive programming through Schneider Electric software enables rapid application development, easy duplication of configurations, and simplified maintenance. Available libraries include function blocks tailored to HVAC and utility applications: fan control, compressor management, temperature regulation, purge cycles, pressure monitoring, or pump management. The controller also ensures smooth communication with higher‑level systems through its communication interfaces (Modbus RTU or RS‑485 depending on model). This connectivity allows integration into a global supervision architecture, enabling transmission of machine statuses, alarms, and physical measurements. The TM173 can therefore operate in a multi‑device network, driving a local module while communicating with a main PLC
