The I/O modules in the MX-System offer a wide choice for all signal types and directions. The MO3204-6666-1112 allows the direct connection of up to four temperature sensors and can measure the resistance and voltage in the specified ranges for each channel. This means that all RTD sensors and thermocouples compatible with the measuring range can be connected. The signal state is shown on the display; the signal interface is established via screw-type M12 connectors.
