Overview
The IntelliLogger models equipped with the BBus expansion port capability can have their channel count expanded by simply daisy-chain connecting one or more ILIM-x Interface Modules. A CAT-5 Ethernet cable is used (provided with the module) for the interconnection and up to 100’ can separate the IntelliLogger and a module. For applications with 5 or less modules, the IntelliLogger System Base can provide both the communication AND the power for the modules via this BBus interconnect.
Alternatively one or more ILIM-x modules can be fastened to the back of of an IntelliLogger System Base making for a stair-step stacked instrument. Brackets are available from Logic Beach for module stacking.

ILIM-7; Isolated Analog Interface Module (Back to Top)
( View Additional Images)
The ILIM-7 is a very high resolution, high accuracy Interface Module containing 8 isolated differential inputs and one excitation voltage output. The desired resolution of the readings can be set by the user from 16 bits (one part in 64,000) to 20 bit (one part in a million). Filtering (e.g. 50 and 60Hz rejection) and extended settling time for higher output impedance signals is supported on a channel by channel basis.
Note that the BBus daisy-chain utilizes readily available CAT-5 type Ethernet cable, the communication on the actual BBus is proprietary to the IntelliLogger family and is not Ethernet. Ethernet communication is offered on the IntelliLogger Ethernet port.
Isolation which is integral to each of the ILIM-7 input channels avoids field installation problems associated with common mode input exceedance issues… making the real-world deployment and configuration of the IntelliLogger faster and easier.
Each input may be individually configured as:
THERMOCOUPLE:
Seven types of thermocouple are supported and direct thermocouple connection can be made to any of the ILIM-7 eight channels via the associated terminal strips. J, K, E, T, R, S and N type thermocouples are currently supported.
COLD JUNCTION COMPENSATION FOR THERMOCOUPLE MEASUREMENT:
The Cold Junction Compensation (CJC) is handled automatically by the ILIM-7 via an onboard temperature sensor. This sensor can also be accessed for monitoring and/or logging of the actual ILIM-7 unit temperature via the Program Net.
DC VOLTAGE:
All 8 isolated inputs can be individually configured for 8 different bipolar DC voltages input ranges. Eight ranges are provided supporting +/-19mV to +/-2.2 Vdc full scale.
Additionally, four of the channels can be configured for full scale input of an additional 3 ranges… +/-7.5Vdc, +/-15Vdc and +/-30Vdc.
DC CURRENT:
All 8 isolated channels can be individually configured for DC current measurement as well via the integral precision low TC 100 ohm burden resistor. Eight bipolar DC current ranges are user selectable on a channel by channel basis, ranging from +/-190uAdc to +/-22mAdc full scale.
VEXC OUTPUT:
A stable, 5Vdc output (25mA max current) output is provided on each ILIM-7 and can be used for sensor excitation or other channel reading coincident applications.

Channels can be field configured independently for bipolar Vdc input, Thermocouple input or mAdc input.
These channels utilize a high resolution ADC providing up to 20 bits of signal resolution (i.e. one PPM). The default is 16 bits (one part in ~64,000) and the setting is user programmable.
Channels are all isolated from each other as well as from the system base.
When channels are configured for thermocouple applications, the CJC temperature is automatically sensed and used in compensation.
Four of the eight channels when configured as Vdc inputs can be programmed to accept 3 additional higher voltage ranges up to 30Vdc.
Contact Logic Beach for information about higher Vdc input ranges.

The IL-80 model IntelliLogger has one ILIM-7 module integral to the System Base Enclosure and the BBus connection is made internally. Hence, the IL-80 high resolution analog inputs meet the same versatility and specifications as the stand-alone ILIM-7 modules explained here.
ILIM-2; Digital Interface Module (Back to Top)
The ILIM-2 is a high channel count module dedicated to digital (Event, Count and Frequency) measurements. As other IntelliLogger family Modules, it connects to the IntelliLogger System Base via the daisy-chain BBus… and self-identifies within the HyperWare-II Programming environment for quick and intuitive configuration.
The module is well suited to electrical, gas and water Sub-Metering applications, Event logging and power monitoring using pulse output kWh transducers.
