The Wilkerson Instruments DR9050 wireless master control unit is an RF transmitter/receiver that is used to poll data from companion DR9051R wireless signal transmitters. 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.
Wilkerson Instruments DR9050 wireless signal transmitters output 100mW (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 Wilkerson Instruments DR9050 site.
Screw terminal blocks that plug into the case allow easy wiring and removal of Wilkerson Instrument products. All of the DR Series of products provide transient protection to help eliminate damage from lightning and from other transients created on the power and signal leads.
