Mixed Analog and Digital I/O Modules

A mixed analog and digital I/O module is an expansion unit that combines digital inputs, analog inputs and relay or transistor outputs in a single housing. It is preferred over using separate modules in small machine and building automation applications where many on-off signals are read alongside only a few analog measurements. This category includes GEMO AR2-G1 expansion modules: models offering 12 digital inputs, 2 analog inputs of 0-10 V and 10 outputs are available with relay or transistor outputs and 24 V DC or 230 V AC supply. Select the module according to its compatibility with the GEMO AR2 main unit, the supply voltage, whether the output will be relay or transistor, and the signal range of the analog input. A relay output can switch AC and DC loads, while a transistor output is suited to fast and frequent switching of DC loads. These modules are not general-purpose I/O modules that fit every PLC; the manufacturer describes them as a GEMO AR2 smart relay expansion connected over RS-485, and the analog inputs are for 0-10 V signals.

How to choose Mixed Analog and Digital I/O Modules

A mixed analog and digital I/O module is an expansion unit that combines digital inputs, analog inputs and relay or transistor outputs in a single housing. It is preferred over using separate modules in small machine and building automation applications where many on-off signals are read alongside only a few analog measurements.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
