Using the IntelliLogger™

Differences between models are explained in Chapter 2 and mainly relate to the analog and
digital input/output (I/O) capacity and channel expansion features. An IL-80 is shown in Figure

Channel count (analog and digital) in an IntelliLogger system can be expanded by the addition
of one or more Interface Modules. Modules are connected to the System Base via the integral
BBus connectors… allowing up to 16 modules to be daisy-chained.
One of the family of Interface Modules, the ILIM-7 (Figure 1-2) for example adds eight optically
isolated analog input channels to the system. Each of the eight analog inputs can be user
configured for use with thermocouple, voltage or current type inputs.
