4 VSmart Module (only for Integra 500)
Figure 4-1 VSmart Module (Inside)
The VSmart module is where all monitored devices (probes, sensors,
and line-leak detectors) are physically connected to the system
through Intrinsically Safe (IS) barriers. A VSmart module houses up
to two (2) I.S. barriers; each I.S. barrier has four (4) channel inputs.
Each I.S. barrier supports up to 64 peripheral devices; thereby,
allowing for a maximum of 128 devices per module. The number of
devices that can be connected to each channel of the VSmart module
depends on the type of device.
NOTE: Conduit is recommended for Petro-Net™ connections
between VSmart Modules and consoles, but it is not required.
Part numbers for the barriers:
P/N: 20-4344 12V Barrier for VSmart 924/924B probes and standard
and multi-drop sensors (Green Label)
P/N: 20-4345 24V Barrier for VSmart Flex probes and EECO probes
(Orange Label)
4.1 VSmart Specifications
*Maximum I.S. Wiring Length is the maximum length of cable to be
used to connect all probes or sensors on an individual channel. The
length includes run of cable from an I.S. Barrier to each probe or
sensor board in the string.
**Maximum Petro-Net extension using RS-485 is the maximum
length of Petro-Net cable to be used to connect all Petro-Net devices.
