Wilkerson Instrument DR9050 Data sheet
DR9050
WIRELESS MASTER CONTROL UNIT
DESCRIPTION
The DR9050 is an RF transmitter/
receiver that is used to poll data from
companion DR9051R’s. A user Modbus
RTU Master Controller (PLC / DCS etc)
initiates a query to a Modbus address.
The DR9050 MCU determines the
correct DR9051R for this address, polls
the DR9051 and returns the requested
data. A single DR9050 can poll up to
247 DR9051R’s utilizing a single Hop
sequence.

(21.5 dBm) in the 915 MHz unlicensed
ISM band. It uses frequency hopping,
spread spectrum* technology to allow
multiple systems to work in the same
locale without interference.
Setup software is provided to program
all the system addresses into the
DR9050. Addresses may be edited and
Hop Sequences can be changed for the
system. All setup can be done at the
DR9050 site.
