- Local I/O
Depending on the expansion module references, there may be fewer than 7.
- Remote I/O
TM3 expansion modules are powered by logic controllers via the bus connector on the side of the products. This connector delivers 2 voltages, 5 V and 24 V. You should therefore calculate the total TM3 expansion module consumption and check that it is compatible with the maximum current delivered by the controller. SoMachine Basic hardware configuration is an easy tool to check the compatibility. Please refer to the attached file for reference.
