Digital IN Module IN-02U-S4

Flush-mounted Input Module for connecting conventional pushbuttons and switches to the subnet. The module can be used to transfer 2 commands to the BUS system. This module offers the possibility of subaddress management.

Quick Facts

  • 2 digital inputs
  • Subaddress management
  • Connecting standard buttons
  • Evaluation of presence sensors
  • Systems with many addresses in one subnet

The flush-mounted IN Module is used to connect conventional pushbuttons and switches to the subnet. With the module 2 independent commands can be transferred to the BUS system. The buttons/switches are connected by means of wires. The difference to the standard IN-02U Module lies in the possibility of subaddress management. With this it is possible that four IN-02U-S4 Modules share one address.
