b Modicon 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. For the Modicon M221 and M221 Book logic controllers, you should therefore calculate the total TM3 expansion module consumption and check that it is definitely compatible with the maximum current delivered by the controller. This information is available on each product data sheet or in the hardware reference guide. This can be checked very quickly in the SoMachine Basic programming software setup page. b For Modicon M241 and M251 logic controllers, up to 7 TM2 expansion modules can be attached regardless of these module references.
