TW-4
2Wire + Radio Decoder
GENERAL PROPERTIES :
• 24Vac Controller for 2-WIRE and RADIO decoders .
• The same programmer acts as a programming console for the field decoders . Easy and quick to program .
• Number of decoders : Up to 127 wired stations + 128 radio stations + master valve + sensors .
• Number of programs : 6 independent and overlapping programs .
• Number of starts : 6 starts per program .
• Cycle duration : up to 7 days . ( days , interval , odd or even ).
• Programming times : from 1 minute to 12 hours per valve , with descending counter in minutes .
• Wire range up to 1,500 m { 5000ft }, and Radio up to 12Km ( 7.5Mi ).
• MANUAL START of stations and programs with “ countdown ”.
• Programmable delay between stations and / or pump .
• DOSIFICATION PROGRAM of up to 4 fertilizers with independent waiting time and dosing time .
• Up to 8 Master-Valves and / or Pumps . Configurable .
• Communications port for remote control through Hydro-Plus by GPRS or Wifi communication .
• Up to 16 sensor inputs : 2 of ON - OFF / 4 of 4 - 20mA / 6 of digital CC / 3 of digital 1 - 255Hz / 1 of SDI-12 .
• Outdoor box with press releases-catch and safety lock .
• Outlets for outdoor antenna and sensor inputs .
• Program “ D - F ” configurable in minutes or seconds with inhibition from the N / C sensor . This allows us to connect pressure differential pressure switches for the automatic WASHING OF FILTERS , connection to fertilizer injection pumps or short sequential irrigation .
• Easy installation , programming and use thanks to its versatile design and its hybrid control system .
• Rotary mechanical control menu and 4-key ergonomic keyboard .
• Digital display with icons that make its management very logical and simple .
• PAUSE and DELAY menu positions .
• Budget adjustment between 10 % and 400 %.
• Input for activation of master valve and two inputs for sensors , one normally open ( differential pressure switch for washing filters ), and the other normally closed ( rain sensor ).
• Non-volatile memory that keeps the programs made and are not deleted in case of blackouts . Internal Lithium battery to maintain the time and calendars in case of power outs .
