TW-4 Controller for NG Decoders

TW-4 Data Sheet

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.
