DI 8xAC/DC 60...230V VIPA 221-1FF20
The digital input module accepts binary control signals from the process
and provides an electrically isolated interface to the central bus system.
The module has 8 channels, each one with a light emitting diode to indicate
the status of the channel.
• 8 inputs, isolated from the backplane bus
• Nominal input voltage 60 ... 230V AC/DC
• Status indicator for each channel by means of an LED
