R1 Relay

Single-channel relay block

๐Ÿ’Ž Possibilitiesโ€‹

  • Contacts NC, COM, NO (changeover relay)
  • Manage loads by type Enable/Disable
  • Control of lighting, ventilation, heaters and other loads
  • Management of low-current devices with dry contact inputs

R1

โ“ Descriptionโ€‹

Relay block R1 is intended for switching signals and elements of electrical circuits in automated control systems for lighting, power distribution equipment, ventilation systems, climate and other electrical loads, in the fields of industry, housing and communal services and household services.

Interfaces
USBService connection
RS485**YoctoBUS or Modbus RTU
Ethernet**IEEE 802.3 10/100BASE-T (http, UDP)
WiFi**IEEE 802.11 (http, UDP)

** Depending on unit configuration.

tip
  • For YoctoBUS blocks: the default exchange protocol type is YoctoBUS, initial configuration is not required.
  • For YoctoLAN units: when connecting to the network via Ethernet, initial configuration is not required, when connected via WiFi, you must set the SSID and Password using the CONNECT Configurator software.
note

To integrate the unit into third-party systems, the protocol and RS485 exchange rate, as well as network settings, are set through the free, cross-platform CONNECT Configurator software.

note

It is recommended to configure the RS485 parameters using the CONNECT Configurator software

ModbusRTU mode

The unit supports standard exchange via the ModbusRTU protocol.

  • Reading the state of the register is carried out by the command 3.
  • Record of value in the register is carried out by the command 6.
