Four Parallel Controller models
The Parallel Controller range is separate from the standard Generator Controller range and is specifically listed for systems using two or more units in parallel.
Compare three representative models
Start with display size, I/O capacity, input range and communication requirements.
4.3-inch Display
Representative 4.3-inch model with 8 digital inputs, 8 relay outputs and 4 analog inputs.
5-inch Display
Representative 5-inch model with 10 digital, 10 relay and 5 analog I/O points.
Higher I/O Count
5-inch model with the highest listed I/O counts and an Ethernet/audio port.
Controller capabilities
Available I/O and interfaces vary by model. Final model choice should follow the actual generator system and control requirements.
