Use a 12V lead-acid battery well dimensioned to supply everything during blackout.

Also, in this way it's possible to get everything working even in case of power outage (domotic controller, domotic modules, network switches, routers, NVR and IPcams). Use a 12V power supply unit with backup battery charger, to avoid trouble on RaspberryPI or other devices.Often it's important to have a stable power to supply your Smart Home, to avoid troubles with the domotic controller (RaspberryPI or other), have internet connection always ON and are able to manage alarm sensors even in case of power outage.

The following schema shows how to use the normally-closed contact of SPDT relay to supply a router.Ī script will check that internet is working, and in case of failure activate the reset to turn power supply OFF for 10 seconds, resetting the router. With Domoticz it's easy to get heating/cooling system with heat pump, optimized to consume most energy from photovoltaic, and a air renewable controlled mechanical ventilation with chiller and coil that regulates the relative humidity to get the maximum comfort.įor security reasons, do not mix high and low voltage loads in the same block! For example it's not safe to connect, on Block3, a 230V valve to RL8 and a 12/24V valve to RL7! On each relay block it is possible to use only low voltage or only high voltage loads.ĪDSL router controlled by Domoticz script to prevent hang-up The following simple diagrams represents the connection to a heat pump (controlled by low voltage signals), a ventilation system (controlled by low voltage signals) and a 3-vias valve (supplied by 230Vac). Application notes Heating/ventilation system (1): can be used as BLIND output, to open a blind/curtain, but only the previous port can be configured in Domoticz as OUT_BLIND because, when configured as OUT_BLIND, DomBus device automatically configure the next port to drive a relay in open direction. SPDT relay output, NO + NC contacts, 10A 250Vac or 250Vdc output capability. SPST relay output, NO contact, 5A 250Vac or 30Vdc output capability. To reduce noise and reflections on the bus, enable the termination resistor (shorting Rbus PCB jumper) on the two furthest ends of the bus.Use a 4 wires shielded cable for the bus, using two lines to send power supply (12-14Vdc) protected by a fuse.Do not use capacitive loads with high inrush current (bad power supplies, ballasts.Relays are divided in 3 blocks: do not mix high voltage (230V) loads and low voltage (5/12/24V) loads on the same terminal block!.

low power consumption: 0.75mA ( 9mW) stand-by current with all relays OFF, and 41mA ( 500mW) with all relays ON.

8-35Vdc power supply (internally regulated by a switching mode power supply circuitry that minimize power consumption and dissipation).

Do not mix high and low voltage signals inside the same block!

Relays are divided in 3 blocks, each block respects the creepage distance from other blocks.

2 relay outputs, SPDT (normally open and normally closed contacts on screw terminal block) with 250V 10A contacts.

6 relay outputs, SPST (normally open contact on screw terminal block) with 250Vac/30Vdc 5A contact (max 30Vdc in case of DC load, 250Vac in case of AC load).

Suitable to be used as relays module with Domoticz, Home Assistant: using a simple 4 wire shielded cable it's possible to supply and interconnect up to 30 modules like this, through RS485 protocol already implemented in Domoticz (a plugin must be installed) and Home Assistant (installing the custom component): RS485 is a strong communication system, easier to be connected than ethernet, with no RF pollution, and already includes 12/24V power supply in the bus cable.

It can be connected to the Domoticz, Home Assistant controllers by a RS485 serial bus (4 wires, 2 for 12/24V power supply, and 2 for data at 115200bps).Īs other DomBus devices, DomBus31 provides excellent performance in terms of power optimization: with all 8 relays active (the worst case), the power consumption is only 500mW! As a comparison, KMTronic 8 relays module consumes 12W, Denkovi 8 relays board consumes about 3W, Sonoff Dual R2 consumes 2W with only 2 relays enabled. 6 relays are SPST (Normally Open outputs) with 250V 5A max capability, and 2 relays are SPDT (Normally Open and Normally Closed outputs) with 10A capability.

Creasol DomBus31 is a din-rail relay module, 115x90x40mm, with 8 relays outputs.
