4JG7-1B DC Type Solid State Relay





Suitable for defense and industrial control fields, such as computer interfaces, digital circuit interfaces, signal transmission, numerical control equipment and measuring instruments, suitable for harsh environments.


  • The four sets of inputs are positive, the negative side is controlled, and the four sets of outputs are independent of each other. The application can be used separately for each group, the inputs can be connected in parallel, and the outputs can be used in series and parallel.
  • Special requirements may not be used to install studs.​
