DomBus1 is the first domotic module of DomBus serie, integrating 6 inputs, 2 relay outputs, 1 AC input.

Creasol DomBus12 is a compact module, 40x30x11mm, with 9 configurable inputs/outputs.
It can be connected to the Domoticz controller by a RS485 serial bus (4 wires, 2 for 12/24V power supply, and 2 for data at 115200bps).

As other DomBus devices, DomBus12 is designed to consume low power, be reliable, fully configurable and easy to use. Each port is fully configurable, e.g. as analog or digital input, twinbutton (double button), counter, buzzer,  NTC 10k, ... 2 ports may be used as open-drain output, to activate 2 external relays or LEDs.

Creasol DomBus23 is a module for home automation system with several different kind of configurable inputs/outputs in a short size:  74x72x24mm.

AVAILABLE IN TWO VERSIONS: DomBus protocol and Modbus protocol!
Creasol DomBus31 is a din-rail relay module, 115x90x40mm, with 8 relays outputs. 6 relays are SPST (Normally Open outputs) with 250V 5A max capability, and 2 relays are SPDT (both Normally Open and Normally Closed outputs) with 10A capability. High efficiency module, with very low power consumption, only 600mW with all relays ON.

DomBus32 is a DIN-RAIL module, 54mm wide, with 3 relay outputs, 3 AC inputs and 5 low-voltage I/Os.
AVAILABLE IN TWO VERSIONS: DomBus protocol and Modbus protocol!

DomBus33 is a DIN-RAIL module, 54mm wide, designed to control an existing lighting system with 3 lights using 115/230V pushbuttons and step-by-step relays.

DomBus33 has 3 relay outputs, that can be used to send pulses to existing step-by-step relay coils to switch lights ON/OFF, 3 AC inputs to be connected to the step-by-step relay contact to know the ON/OFF light status, and 5 low-voltage I/Os that can be connected to additional pushbuttons and/or switches to activate/deactivate single lights, or activate/deactivate all lights (useful to turn all lights OFF when leaving home).
In this way lights can be controlled by both existing pushbuttons and domotic controller (smartphone, web interface, automation, scenes, groups).

To simplify wiring, the terminal block has 3 terminals for relays, 3 for AC inputs, and 1 terminal for the common (usually Neutral, but Line can be used as well): in this way it's easier and faster to connect the module to the light system. Please take care to connect only loads that are protected by the same RCCB (circuit breaker).

As other DomBus modules, all ports can be configured in many different ways, and also this module supports DCMD, commands sent to the same or other modules to perform simple actions, that permit to achieve high reliability (DCMD commands work even if domotic controller is not operational) and easy programming (don't need to create automations in the domotic controller, just configure DomBus ports to perform actions on events). Last, but not least, as other DomBus modules it's optimized to get low power consumption, less than 10mW normally (0.75mA @13.6V) and less than 150mW when all relays are ON (10mA @13.6V).

• 5 programmable I/Os
• 8-25Vdc power supply
• 10mW power consumption
• 150mW max power consumption
• 52x89x65mm

Application notes

DomBus34 is a DIN-RAIL module, 54mm wide, designed to interface up to 4 power/energy meters, type DDS 238-2 ZN/S (Modbus), to measure power and energy (both imported and exported), voltage frequency and power factor.

Creasol DomBus36 is a din-rail relay industrial-grade module for building automations and home automation systems, 115x90x40mm, with 12 relays outputs, SPST (Normally Open outputs) with 250V 5A max capability, divided in 3 groups of 4 relays, each group with a 5-position screw terminal blocks: 1 common + 4 outputs

Domotic module, 115x90x40mm, supporting both DomBus and Modbus RTU protocols, that integrates 12x low voltage analog/digital inputs, 3x relays outputs, 3x 115Vac / 230Vac inputs. Optionally it is able to control and monitor the power supply fed to a burglar alarm external siren.

Suitable to interface alarm sensors (magnetic contact sensors, PIRs, tampers), monitor power outage (by the 3 AC inputs) and control up to 3 outputs (relays).

Creasol DomBusEVSE  is a fully tested DIN rail module, designed for Domoticz, Home Assistant, OpenHAB, Node-RED, ioBroker, ... home automation systems, to  charge electric vehicles using the standard  IEC 62196-2  Mode3  (AC charge, up to 22kW power).

It works as  stand-alone  (with or without any domotic controller) or in  managed mode   (charging current controlled by a domotic controller).

Creasol DomBusTH is a fully configurable small electronic board, 32x17mm, that can fit any blank cover with a 3.5mm hole in the centre, needed by the thermal/humidity sensor to exchange air with the room and to get the 3 LEDs light out. It can be connected to the Domoticz controller by a RS485 serial bus (using a standard alarm cable with 4 wires, 2 for 12/24V power supply, and 2 for data at 115200bps). Available in both DomBus and Modbus protocols

ESP8266 is a very powerful and cheap MCU equipped with WiFi transceiver, very useful to expand inputs/outputs of a Raspberry/Domoticz controller.

Creasol DomESP1 board is designed for ESP8266 module NodeMCU V3, with 900 mils header pitch (optionally, soldering additional headers, it's possible to use the 1100mils module or WeMos D1 mini module), and integrates the whole circuitry to manage digital inputs, one analog input, 4 relay outputs, 1 low voltage output, I2C bus, 1wire bus and 2 mosfet outputs with 12A 30Vmax capability.

Creasol DomRelay2 is a compact module, 43x24x25mm, within 2 relays with 12V 200mW coil, 250V 5A SPST contact with special material designed to prevent contact welding due to excessively high surge current load (capacitive loads or tungsten lamps).

Contacts are protected from overvoltage by metal oxide varistors; coils are protected from overvoltage by free-wheeling diodes.

Relay coil should be driven at 12Vdc 17mA: using DomBusTH or DomBus12 modules it's possible to drive relays using a lower power system, consuming less than 1/4 of nominal power.
