System G4

Generation of 4 digital inputs and outputs, which was launched by Opto22 in 1989, provides a higher capacity than older modules maintaining single-channel flexibility. LEDs diodes and fuses are usually on the modules rather than on the frame to be visible and easily accessible for servicing. To meet the requirements of your system, the family of G4 digital inputs and outputs includes a wide range of modules, mounting frames and accessories.
