Squirrel Modules

Each Squirrel Datalogger typically contains one CPU module and at least one input module. The CPU module contains two inputs of its own; one event input and one pulse input. Up to 8 input modules can be combined into one Squirrel Datalogger, for a maximum total of 124 input channels.
