A724 UHF RTU

The A724 addSWITCH Series 4 is an extremely robust RTU (Remote Telemetry Unit) with an integrated 10 mW radio module. It is fully compatible with all other members of the Adcon UHF radio family, be that the A733 addWAVE, the A740 addNODE or the A731 addRELAY. It can thus easily be integrated into existing Adcon networks, offering transmission distances of up to 1.000m.

Its extremely low energy consumption allows for permanent solar powered operation. Its internal battery pack powers the radio and the logger and charges the capacitors needed to activate latching solenoids with up to 15VDC.

FEATURES

Features:

  • Valve Operation- An addSWITCH can operate 4 latching solenoids, supplying them with 5.5 to 15V DC (programmable). It features a 6-pin Switchcraft connector to connect to the solenoids. What happens if my OFF signal gets lost?-That’s a major concern for most growers! With the addSWITCH lost OFF commands are a thing of the past. The ON commands issued by the Adcon addTIMER software also contain the runtime information, which will make the addSWITCH shut off the valves automatically after the desired runtime – WITHOUT the need to send an OFF command! However, should you want to end an irrigation shift prior to the preset runtime you can certainly do so by transmitting a separate OFF command – just click on the STOP button in the addTIMER! Meter Reading and Irrigation Gauges- In addition to operating solenoids A724 Series 4 also features four pulse counters. This enables you to attach four water meters, or four irrigation gauges, or a mix thereof. This will provide you with additional information if your irrigation system performs correctly.

 

Benefits:

  • Irrigation: The A724 addSWITCH is mainly used in agriculture to control valves and pumps. Wind Machines: many wind machines installed for frost protection feature a motor that can also be started by means of a latching solenoid. Water Management: while most reservoirs are filled based on their level it might be a smart idea to start the pump and fill it when the energy rates are low!
