Extended Signal Conditioners
The inputs are a long distance away from the desired output location.
Example: thermocouple inputs are on the plant floor and you need the 4-20mA outputs in the control room
Signal Splitter for Analog, Discrete, or Temperature Inputs
One voltage or current input can be sent to multiple remote voltage or current outputs at up to twelve locations.
One digital contact can be connected in parallel to yield multiple contact outputs at up to three remote locations.
One temperature (thermocouple or RTD) input can be mapped to two different IP addresses.
Multiple inputs are mapped to multiple outputs over Ethernet media.
One output module receives signals mapped from multiple input modules.
Analog inputs mapped to remote analog outputs connected to alarm module.
Remote Selector Switch
Discrete inputs mapped to discrete outputs.
Provide measured signal from remote source for input to PLC, DCS, controller, recorder, or display without network communication capability.
Provide input to meters, lamps, or buzzers from remote I/O source
Tank Level Monitoring and Pump Control
Provide 4-20mA or contact signals from remote level sensors to pumps
Valve Control Loop (using 951EN modules with both inputs and outputs)
Valve position represented by 4-20mA input to Module A mapped to output channel on Module B connected to a PLC. Then reverse direction from PLC back to control valve using the same two modules. PLC signal input to Module B is mapped to output channel on Module A to control valve.
Event Driven vs. Polling
Discrete inputs mapped to discrete outputs that switch on change-of-state.
i2o's Cost Reducing Benefits
Using existing Ethernet infrastructure eliminates need to run new wire.
No master controller, HMI software or special drivers required.
Enables older PLCs with analog input cards to interface with Ethernet networks.
Replaces analog leased lines with digital communication (broadband, Wi-Fi, etc.)
Complete installation and setup in minutes. Easy installation, space-saving design, and quick web browser configuration.
