Large Decoder Interface (LDI) and Small Decoder Interface (SDI)

SiteControl Only

The LDI/SDI Two-Wire Decoder Interface serves as an interface between the Central Controller and Rain Bird field and sensor decoders on the SiteControl System.

Genel Özellikler

Large Decoder Interface (LDI) and the Small Decoder Interface (SDI) serve as an interface between the central controller and Rain Bird commercial field and sensor decoders
Rain Bird field and sensor decoders include - FD-101, FD-102, FD-202, FD-401, FD-601, SD-210.
LDI can interface with up to 500 decoder addresses and can activate up to 1,000 solenoids (specific performance depends on system design – please consult Rain Bird Decoder Design Guide)
SDI can interface with up to 200 decoder addresses and can activate up to 400 solenoids (specific performance depends on system design – please consult Rain Bird Decoder Design Guide)
LDI and SDI come standard with terminals for 4 wire paths.
Up to 200 total pulse and 200 static (switch) sensors can be set up per system with a maximum of 10 sensor decoders per SDI or LDI (specific capacity on SDI or LDI wire paths depends on system design)
Ground the two wire path at the SDI or LDI decoder interface using a Rain Bird MSP-1 surge protector.
Ground the two wire path every 500’ using an LSP-1 Line Surge Protector or the LSP-1 that is built into an FD-401 or FD-601 field decoder.
All LDIs and SDIs shall be grounded to a 10-ohm or less earth ground.
LDI and SDI are UL and CE listed.
Flow sensors used in a decoder system do not require the use of a pulse transmitter.
