Panel Module I/O-08T-PNP

The I/O-08T-PNP is mainly used in panel applications. Due to its small size, the module can also be optimally integrated into small control panels.

Quick Facts

  • 8 optocoupler inputs
  • 8 transistor outputs PNP
  • For 8 buttons with feedback signal
  • Panel connection

The I/O Panel Module I/O-08T-PNP can be used to connect 8 buttons and 8 signal lamps to the ISYGLT BUS system. 8 short-circuit-proof PNP transistor outputs are available as outputs and 8 optocoupler inputs 12-48V each on a common counter potential are available as inputs. The functions of all inputs and outputs are freely programmable via the software.
