I/O Module I/O-21L-230V-3A

I/O Module with 2 binary inputs and 1 triac output for 1 circuit. 

Quick Facts

  • 2 binary inputs 24V DC
  • 1 Triac output 230V/3A (700W) "zero crossing circuit"

The Installation Device is a module that has been specially designed for direct installation in lamps in terms of housing and technical data. With the triac output 1 lighting circuit, or heating circuit can be switched. The inputs can be queried via the subnet.
