The Somat eDAQ Digital Input/Output Layer (EDIO) is an extremely versatile layer that can measure digital inputs/outputs, pulse counters, quadrature decoders, vehicle bus and GPS. The EDIO offers 24 channels that can be used as digital inputs/outputs with 12 additional channels for wide-range inputs.

Integrated in the digital channels are 18 configurable pulse counters. One layer can also support up to two independent vehicle bus interfaces via the use of Vehicle Bus Smart Modules.

The GPS communications port is designed to work with Somat GPS devices.
