The total number of sensors is really
unlimited for a MAARS System, if you define a system as
consisting of more than one MAARS Monitoring Unit (MMU).
Multiple MMU’s are connected together via Ethernet, so the
actual number of sensors in a system is really limited by
the network bandwidth. In today’s networks with large
bandwidth, there is no practical limit.
Instead, it is much more practical to
discuss the number of sensors that individual MMU’s can
input. Each MMU has a maximum of 16 or 32 data inputs.
Models 2000, 3000 and 5000 are 16 data inputs, plus up to 3
tach inputs and two or four relay outputs. Models 4000 and
4010 have up to 32 data inputs and 3 or 6 tach inputs (6 if
a second ADC is used). Four relay outputs are present on the
motherboard, and an additional separate board consisting of
up to 16 relay outputs may be piggy-backed onto the Model
4000/4010 MMU.
