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

I/O module with 8 binary inputs and 8 relay outputs. For control tasks which are switched with 230V.

Quick Facts

  • 8 binary inputs
  • 8 relay outputs, 230V/16A
  • Inputs and outputs in the functions freely and independently programmable
  • Special function: Emergency operation
  • Control of light circuits
  • Control of blind motors
  • Control of heating valves and mixers

The I/O module I/O-08B-230V-16A can be used to switch 8 circuits with a maximum of 230V/16A (2 contacts each on a common root). The phase position of the individual fuses is arbitrary. 8 optocoupler inputs 12-48V on a common counter potential are available as inputs. The functions of all inputs and outputs can be freely programmed via the software.

From production 2015, the modules will be available with the following parameterizable functions:

  • Status of the output relays after Power ON
  • Definition of inputs as currentless OFF or ON
  • Definition of the functions of the BUS inputs
  • Definition of the functions in the operating modes: BUS, BUS failure and emergency operation
  • Safety functions for motor controls (limit switch settings, interlocks, activation times definable, switch-on times)
  • Indication of defined pulse times on the relays
  • Definition of the display LEDs on the module (display inputs or outputs, BUS error, operating mode, running light)
