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

I/O module with 8 binary inputs and 8 Photomos relay outputs for applications with increased switching frequencies.

Quick Facts

  • 8 binary inputs
  • 8 Photomos relays, 5-35V DC or 5-27V AC / 1A
  • Door and sluice control
  • Blinking lights

The I/O module I/O-08E-24V-1A was developed for applications with high switching frequencies. The Photomos relays used can be used to switch 8 circuits with a maximum of 5-35V DC or 5-27V AC / 1A. 
8 optocoupler inputs 12-48V on a common counter potential are available as inputs. The functions of all inputs and outputs are freely programmable via the software.
