BUTTON INTERFACE 1

Momentary Switcher / Manual Gate Generator

The EMW Button Interface 1 is an auxiliary module that has 3 main functions: It can be used to momentarily switch an incoming signal on/off, generate a manual trigger or gate signal (5v), or to produce an adjustable 0-10V signal control voltage signal. It’s a great module for manually controlling your modular system.
