Schneider Electric has announced that the Modicon M221 logic controller product offering now includes Sink Outputs (along with the Source Outputs that were already available), extending the range of products to suit various wiring habits.
The Modicon M221 Sink Outputs come in 6 different units, with options ranging from 16-40 I/O, and the option for Ethernet embedded. The models have 9 to 24 discrete inputs and 7 to 16 transistor outputs. All units have 2 analog inputs and 2 fast outputs. Furthermore, the 40 I/O model offers Pulse Train Outputs (PTOs) which allow for control of up to 4 axes in pulse direction mode and up to 2 axes in CW/CCW mode.
M221 Sink Outputs use SoMachine Basic 1.4 or higher. SoMachine Basic is available for free download on the Schneider Electric website.
