ACC Advanced Customizable Controller

ANALOG INPUTS

A range of input modules are available from simple single channel linear inputs to multi-channel combination modules. ACC input modules provide direct sensor connection, eliminating the need for specialized signal conditioning hardware. Examples of these include digital frequency, period and quadrature signal inputs for flow and position sensors using rotary encoders. Linear inputs are also available for temperature sensors. We are continuously developing new input modules.
