Using an addressable RS-485 Modbus
communication protocol, the 301C uses
daisy chain wiring requiring only 2 pairs of
wires to connect up to 96 transmitters on the
3 input channels. This simplifies installation,
in turn lowering costs. The 301C’s zoning
and averaging abilities significantly reduce
operational and maintenance costs.
Zoning/Averaging Capabilities
Reduce Operational Costs
The 301C controller offers unique zoning
capabilities which permit the averaging and
comparison of multiple sensor readings.
Zoning can reduce operational costs by
ensuring that localized brief fluctuations
registered at a single transmitter do not
activate relays. For example, a car idling in
a parking structure may locally increase a
reading at a nearby transmitter. Rather than
activating a fan as a result of the temporary
localized fluctuation, zoning can be used
to limit relay activation until the average
reading for a zone exceeds a set-point.
This can reduce run time of fans, yielding
savings in both energy usage and wear and
tear. The 301C has the capacity to manage
input from three Modbus channels for up
to 96 transmitters and up to 50 wireless
transmitters which can be associated with
up to 126 zones. Transmitters can belong
to an unlimited number of zones, providing
maximum operational and control flexibility.
