The WI-I/O 9-L product provides economical standard “off the shelf” wireless I/O (i.e.
transmitting signals over long distances via radio).
The WI-I/O 9-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 signals
(0-20mA)
Outputs such as tank level indication required motor speed, etc.
Inputs such as measured tank level, actual motor speed, etc.
Millivolt signals and thermocouple
signals
Measurement of temperature using thermocouples, including
cold junction compensation.
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 WI-I/O 9-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.
Weidmuller, Inc. wireless gateway units can act as receiver modules and pass the transmitted
signals from the WI-I/O 9-L-T to an external data bus (e.g. Modbus, Profibus, Ethernet, etc.).
