We stock Telemecanique TSX07 Nano. This is a compact PLC system that is available in sizes ranging from 10 up to 24 built-in I/Os. It was intended for small and simple applications. Some modules can however be expanded by more I/O and some of the base modules even have an analog input, which expands the use of Telemecanique TSX07 Nano.
Telemecanique TSX07 Nano PLCs have a built-in rechargeable battery that is soldered to the circuit board. This battery holds the RAM. We always replace this battery in the Nano PLCs that we sell! There's also an EEPROM in the Nano PLCs where the program can be stored.
The system is long obsolete but we can offer used/refurbished Telemecanique TSX07 Nano spare parts from our stock.
