The output decoder is the device which drives the solenoid. Each decoder has a unique address which is used by ICC PRO to communicate with the decoder.
Decoders operate 24 VAC valves or relays and are available in 1, 2, 4 & 6 Output Configurations. Each output decoder will operate one valve
SENSOR INPUT DECODER
The sensor input decoder captures sensor data for the controller. An input decoder is configured to work with either digital or analog sensors.
Each input decoder has one address and monitors one sensor.
Digital Inputs may include Flow Sensors, Rain & Freeze Sensors (Dry Contact/Status Change)
Analog Inputs may include Pressure Transducers.
SURGE PROTECTION DECODER
The surge protection decoder is required to protect the system from lightning strikes, and electrical surges.
For additional information see Section 4.
