8-way Switching Actuator I/O-08H-230V-16A

I/O module with 8 optocoupler inputs 12-48V AC/DC and 8 relay outputs 230V/16A with manual lever. Wide range of parameterisable extra functions.

Quick Facts

  1. 8 binary inputs 12-48V
  2. 8 relay outputs 230V/16A
  3. Emergency and logic functions
  4. Manual control option
  5. Switching light
  6. Circuits remain in last state in case of voltage failure

The I/O module I/O-08H-230V-16A is designed for applications where manual intervention is required, or where the state of the relays must be maintained in the event of a BUS or voltage failure.

8 circuits with a maximum of 230V/16A can be switched. The phase position of the individual fuses is arbitrary. 8 optocoupler inputs 12-48V on a common counter potential are available as inputs.

All inputs and outputs in the module can be parameterised to various functions and the functions can be freely programmed via the ISYGLT ProgramDesigner software.

To protect the module from dust and unwanted operations, it is closed with a transparent lid. A screwdriver is required for manual operation.

  • The output relays can also be switched manually without programming (commissioning, service, maintenance...).
  • The relay position is maintained even if the supply voltage is interrupted.
  • Each individual output of the emergency module can be parameterised for the operating modes BUS operation, BUS failure, emergency operation (DIP1 ON).
  • The feedback LEDs can indicate the status of the inputs or outputs.
  • Due to the extensive parameter setting options, the module can also be used as a stand-alone module.

Parameterisation with ProgramDesigner

The ISYGLT ProgramDesigner offers a wide range of parameterisation options:

  • Definition of the functions in the operating modes: BUS operation, BUS failure, emergency operation
  • Function assignment per output
  • Synchronisation conditions per output
  • Definition of the 8 LEDs for feedback of the outputs or inputs
