With its high channel density and its small dimensions, the Impact20 I/O fieldbus station is specifically suited for installations in terminal boxes and control panels.

Advantages:
Predefined Inputs and Outputs - Helps facilitate configuration
Single Channel Diagnostic via LED - Indicate failures on the spot
Group Diagnostic via the Bus - Facilitates failure analysis
Channel-Related Shut Down - Only the failed port is cutoff
