Relay Output 1W-UNI: Expander with 4x relay output


Czech version


English version

The Relay Output 1W-UNI expansion module allows to connect 4 relay outputs (NO/NC) rated up to 50V / 1A to the Ares 12 GSM remote monitoring unit.
Connect a horn, an alarm indicator or a relay to disconnect power over the 1-Wire UNI (RJ11) bus.

A 1-Wire UNI expansion module with relay outputs for Ares 12.
The relay outputs connected to the Ares 12 GSM remote monitoring unit can be controlled in three ways:

  • On/off switching using the SensDesk portal and its web interface
  • Sending text messages (SMS) directly to the Ares device
  • Local conditions (alarms) in the Ares unit (e.g. to switch a relay when a temperature is too high or too low)
  •  

A maximum of 2 Relay Output 1W-UNI modules can be connected to one active port (RJ11 connector of the Ares unit). To boost the power, an external 5V adapter or the “1-Wire hub Power” powered hub can be used.

 


Practical note:

One Relay Output 1W-UNI module always counts as 4 sensors towards the limit of the 1-Wire UNI bus. In case of Ares 12 (which supports 14 external sensors), 10 basic temperature sensors can be connected in addition to the “Relay Output 1W-UNI” module.

 


 

Features

  • Interface: 1-Wire UNI (2x RJ11)
  • Compatible with: Ares 12
  • Output: 4x relay output – NO/NC (max. 50V / 1A)
  • Addresses: Each digital output uses one unique sensor ID
  • Limitation: The modul counts as 4 sensors on the 1-Wire UNI bus
  • Power: Bus-powered (1-Wire UNI) or external 5V adapter
  • Environment: Indoor use


 

Connecting relay outputs to the SensDesk portal

  • After the relay outputs are connected to the Ares GSM remote monitoring unit, the Ares unit can be connected to the SensDesk.com portal and the outputs become accessible over the web.
  • Individual relay outputs can be controlled from the SensDesk website by simply clicking them.
  • Red means closed contacts, green means open contacts.
  • A text box warns that the output state change will take effect only after the next communication with the device (once per 15 minutes).
  • When the page is refreshed, the box disappears if the output states have been already updated.

Powering several relay expanders

  • Power to the Relay Output 1W-UNI can be boosted with a 5V power adapter.
  • The bottom expander boosts the power for itself as well as for the other two relay expanders in the same 1-Wire UNI branch.
  • Caution: This configuration always counts as 12 sensors towards the limit, regardless of the number of relay outputs actually used.

  • Boosting the power with 1-Wire Hub Power

    • 1-Wire Hub Power is powered from a 12V adapter.
    • The power for each expander comes from an active 1-Wire / 1-Wire UNI port.
    • Caution: This configuration always counts as 12 sensors towards the limit, regardless of the number of relay outputs actually used.
