Cooper Bussmann BU-905U-L Wireless I/O Configuration Manual
INTRODUCTION TO BU-905U-L
The BU-905U-L product provides economical standard “off the shelf” wireless I/O (i.e., transmitting signals over long distances via radio).
The BU-905U-L can monitor and control the following types of signals:
Signal
Examples
Digital on/off signals Outputs such as motor run, siren on, etc. Inputs such as motor fault, tank overflow, intruder alarm, etc.
Analog continuously variable Outputs such as tank level indication required motor speed, etc. Inputs such as measured tank level,
actual motor speed, etc. signals (0-20mA)
Millivolt signals and Measurement of temperature using thermocouples, including cold junction compensation.
thermocouple signals
Pulse count signals Electricity metering, fluid flow, etc.
Internal status signals Analog supply voltage, power status, solar panel status and low supply status, etc.
The BU-905U-L-T monitors input signals and transmits the information to one or more receiver modules. The receiver module(s) reproduce the
signals as digital, analog or pulsed output signals. You can also use setpoints to turn digital outputs ON or OFF based on the level of an analog
input.
