Delisting
If you have any questions, please contact our technical application consultants.
- The digital input module has 8 channels in 2- and 3-wire connection technology.
- The digital input module records binary control signals.
- A filter with a time constant of 1.5 ms is connected upstream of the input channels to suppress interference.
- The signal status of the channels is indicated by one green status LED per channel.

The 8-channel digital input module has 8 channels in 2-/3-wire connection technology with a width of just 12 mm.
It records binary control signals from the field, e.g. from sensors, encoders, switches or proximity switches.
The module has a detachable connection level (RTB) that enables single-wire conductors to be plugged in directly.
The signal status of each channel is indicated by a green status LED.
