(*) The number and/or type of analog/digital inputs/outputs may vary, depending on the Plug-in module (accessory) used. For the table above, it was
considered the standard plug-in module. For further information, refer to the programming manual and the guide supplied with the optional item.
(**) The maximum capacity of 150 mA must be considered by adding the load of the 24 V power supply and transistor output, that is, the sum of the
consumption of both must not exceed 150 mA.
