8-way Switching Actuator I/O-08B-24V-1A

I/O module with 8 binary inputs and 8 relay outputs. For control tasks that only require low voltage.

Quick Facts

  • 8 binary inputs
  • 8 relay outputs, 24V/1A
  • Special function: emergency operation
  • Protective applications
  • Remote controls
  • Fault alarm systems
  • Connection to external systems via contacts

The I/O module I/O-08B-24V can be used to switch 8 circuits with a maximum of 24V/1A. 8 optocoupler inputs 12-48V (4 inputs each on a common counter potential) are available as inputs. The functions of all inputs and outputs are freely programmable via the software.

From production 2015, the modules will be available with the following parameterisable 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)
  • Specification of defined pulse times on the relays
  • Definition of the display LEDs on the module (display of inputs or outputs, BUS error, operating mode, running light)
