The LucidControl USB IO Module can to manage various different signals.

LucidControl USB Digital Input Module reads 4/8 or 16 logic input signals. it is compatible with 5V, 10V and 24V voltage levels, common in automation industry. The inputs can interact with other control system components or e.g. read the state of a push button.

LucidControl USB Digital Output Module is prepared to control 4/8 or 16 power loads like pumps or valves or to create different digital output signals. The outputs are carried out in three different types:
Mechanical relays can be used in order to switch signals like temperature sensors without distortion of the signal.
Solid state relays are the first choice when 24V power loads should be controlled. They provide the best overall performance for most use cases.
Finally, outputs are realized as open collector transistors which are the best choice for fast signal transitions as they are e.g. used for dimming LEDs.

LucidControl USB Analog Input Module is available for voltage input ranges of 5V, 10V and 24V. Especially analog voltage interfaces of 0-10 and 0-24V are often used in the automation industry. It is also available with 4/8 input channels  also for 4-20mA currents.

LucidControl USB Analog Output Module can create 4/8 voltages in the ranges 5V, 10V and 24V. Analog voltage interfaces of 0-10V are very common in the automation industry.
LucidControl USB Analog Output Modules are also available with 4/8 current outputs sourcing 4-20mA. Current outputs can be used to build current loop interfaces which are used in the automation industry for reliable and lossless analog signal transmission over long distances.

LucidControl USB RTD P100 / Pt1000 Input Modules acquire the resistance of 4/8 Pt100 or Pt1000 sensors. They calculate the temperature of a RTD sensor element. The modules fit best for energy management and can be used in order to control other modules of the LucidControl series.
