The usual way involves a controller with some terminals. Each has a wire to a separate solenoid on a water valve that is electrically activated. There is a regular wire that completes the circuit. It daisy chains to any side of the solenoids and reoccurs to the controller. A decoder irrigation system includes an Internet-connected controller. That gets user input and gives a command and power signal and message data to an encoder. The encoder encodes the message and commands onto the power signal. To provide a data encrypt power waveform that is direct over a two-wire path.
The irrigation system further includes one or more decoders in communication. So, a user manages an irrigation system including the two-wire path. From a remote location that uses an Internet-compatible device without particular software installed. Two-wire decoder technology allows control of huge irrigation systems over long distances. By inserting waterproof decoder modules as necessary in a low voltage. Each decoder is addressed uniquely, and both the signal for their address. And the power needed for solenoid operation is sent over the pair of wives.
Benefits of the Decoder System:
- Efficient- the electrical performance of a decoder system is indisputable. It can carry many solenoids over long distances. Longer runs are achievable with heavier wires yet they’re not practical.
- Saves Wire- a decoder system that gains many different users. One of the reasons is the ability to handle 99 stations using two wires only. Rather than more than so many wires. These systems save labor and connectors in connection with a lot of individual wire runs.
- Flexibility- installers can have decoders anywhere along the 2-wire path. The installer can set station numbers. These make it easier to assist changes to the original landscape plan. The number assignment of decoders doesn’t have to be in physical order. Station 3 can be either between stations 1 and 2.
- Lightning-Resistant- A decoder system can withstand lightning. No irrigation system can resist lightning even 2-wire decoder irrigation systems. A decoder system has fewer in the ground. It has great surge suppression and grounding when installed well. Many regions with high-lighting exposure use these systems.
- Troubleshooting- most irrigation systems undergo problems over time. These are because of degradation or faults in the field wiring. A lot of devices and techniques simplify fault-finding today. These are brands providing handheld devices. To help with diagnostics and programming of decoders. There are two wires per path that exist in a decoder system. There is a single result module for the decoder operations. It has diagnostic LEDs for simpler troubleshooting. Conventional ACC is just like the controller operating system. Those common with ACC operations will find it simple to master decoder programming.
- Expandability- it is easy to stretch irrigation systems after the original installation. No longer have to extra wires or retrofit new wiring back to the controller. The installer only has to search the closest point in the current 2-wire path. They can splices in a new decoder station when there is a need for spare valve control.
A decoder system has some differences from conventional wiring. One of these is it permits the handling of many valves over long distances. It is critical for an installer to invest in decoder electronics. The cost for these will be counterbalanced by the wire savings.
