LR44/5N

  • NFC Logic Relay designed for controlling up to 3 pumps
  • App includes pre-defined profiles for specific applications
  • Monitors 5 external N.O. contacts
  • 2 adjustable timers to delay output relays energising/de-energising
  • Fixed timer limits cycle running time before moving to the next
  • Isolated Auxiliary supply
  • 3 x SPNO Relay outputs

An NFC (Near field Communication) Logic Relay designed primarily for controlling up to 3 pumps used for transferring water from one tank to another.

With the ability to monitor up to 5 inputs from normally open contacts, these inputs can connect to float switches for the monitoring of the levels within the tanks as well as receive an alarm trip signal from a pump in the event of a fault occurring, under which condition the operation would then automatically move to the next pump.

Two adjustable timers can be used to delay the relays to both energise and de-energise. These are set using the app installed on a compatible smartphone.

Additionally, the app can be used to load other profiles/sequences in to the relay for other applications.

An auxiliary supply (required to power the unit) must be present for the product to function fully, however due to the NFC capabilities, it is possible to still make adjustments to the relay (i.e. alter a time delay setting) without power applied being applied.

    • No. of monitored inputs: 5
    • Adjustable time delay: 0 – 60s (2 independent timers to delay relays when energising/de-energising)*
    • Aux. supply voltage: 100 – 230V AC/DC (Order Code: 99-3403)
    • Output: 3 x SPNO 5A @ 250V (AC1)
    • Dimensions(mm): W:44 x H:85 x D:63.5

* requires app in order to set/adjust time delays
