Appendix C: Smart Module (only for
Integra 500)
Smart Module (Inside View)
The Smart Module gathers probe and sensor data. Up to four devices
can be connected to the Intrinsically Safe (I.S.) barrier in the Smart
Module. The barrier isolates the module from hazardous areas where
probes and sensors are installed. Up to four (4) barriers can be in
each module, a total of 16 devices per module. Up to seven (7)
modules can be connected to the console via Petro-Net™ (twisted-
pair) wiring, for a total of 128 devices per system. Conduit is
recommended for the Petro-Net™ wiring between the Smart Module
and the console, but it is not required.
For site upgrades from an earlier version of an Integra console in
which the existing Smart Module will continue to be used for wiring
instructions, please see wiring instructions. The Smart Module
supports only one device per channel; therefore, the multi-drop
installation method is not a valid installation for that unit.
NOTE: The standard Smart Module includes one I.S. barrier. The
part number for additional I.S. barriers is 20-4343.
