Panel Module I/O-08T-24V

The I/O Panel Module I/O-08T-24V can be used to connect 8 buttons and 8 signal lamps to the ISYGLT BUS system.

Quick Facts

  • 8 optocoupler inputs
  • 8 relay outputs, 24V/300mA
  • For 8 buttons with feedback signal
  • Panels
  • External control panels

With the I/O Panel Module I/O-08T-24V 8 buttons and 8 signal lamps can be connected to the ISYGLT BUS system. 8 relay outputs max. 48V/300mA are available as outputs and 8 optocoupler inputs 12-48V as inputs, each on a common counter potential. The functions of all inputs and outputs are freely programmable via the software.
