With its four analog inputs and two analog outputs, the SM334 is suitable for connection of analog sensors and actuators. Thereby the module converts the analog signals from the installation into digital signals for the controller and vice versa.
The four inputs can either all be used for resistance measurement (R/PT100) or two inputs each can be used for resistance measurement (R/PT100) and two inputs for voltage measurement in a measuring range from 0 to 10V.
The two outputs furnish 0 to 10V up to a minimum terminating resistance of 2,5 k?. Input and output resolution is 12Bit.
