Creasol DomBus23: Smart Home module with 2x relays, 1x mosfet, ...

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

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, DomBus23 is designed to consume low power, be reliable, fully configurable and easy to use.

Features

2 SPST relay outputs, 250Vac 5A, that can be configured in low power mode to minimize power consumption (less than 70mW/relay, instead of 200mW/relay) and in OUT_BLIND mode to drive a roller shutter motor
1 mosfet output, 30V 10A max, with both digital and dimmer functions, that can be used to drive led stripe regulating the brightness
2 0-10V analog output (can be used to control other electronic boards with 0-10V input, like dimmers): each one can be configured as open-drain output (available through the optional cable) in case that 0-10V analog output is useless
2 I/O lines, each one can be configured as digital input, analog input, twinbutton, counter (for energy gas or water meters), digital output, blind, dimmer (to be connected to external mosfet) and buzzer (piezo buzzer connected to the two lines, in push-pull configuration).
2 low voltage AC/DC opto-isolated inputs, 9-40V
1 230V AC opto-isolated input
7.5-35Vdc power supply (internally regulated by a switching mode power supply circuitry that minimize power consumption and dissipation)
low power consumption: 10mW stand-by power
115200 bps RS485 bus (max length: 1km)

DomBus23 Ports capabilities

Default address: 0xff23

Port#	Name	Capabilities	Default configuration	Description
1	RL1	OUT_DIGITAL, OUT_RELAY_LP, OUT_BLIND	OUT_RELAY_LP	SPST relay output, with 250Vac 5A contact rate, or 30Vdc 5A contact rate. Relay contact is protected from overvoltage by varistor
2	RL2	OUT_DIGITAL, OUT_RELAY_LP, OUT_BLIND	OUT_RELAY_LP	SPST relay output, with 250Vac 5A contact rate, or 30Vdc 5A contact rate. Relay contact is protected from overvoltage by varistor
3	MOS	OUT_DIGITAL, OUT_DIMMER	OUT_DIMMER	Mosfet open-drain output, 30V 12A max, suitable to control led stripes (with the possibility to regulate the brightness using the DomBus dimming function, 0-100% with 5% step) or other DC loads.
4	V1/OD1	OUT_ANALOG, OUT_DIGITAL, OUT_RELAY_LP, OUT_BLIND	OUT_ANALOG	Analog output, 0-10V, suitable to control the 0-10V or 1-10V input of another electronic board (dimmer, heat pump, linear valve, ...). Optionally it's possible to configure this port as open-drain output 40V 100mA max, that can be connected to external leds or relay by using the optional 5-wires cable: od1 pcb jumper must be shorted, in this case.
5	V2/OD2	OUT_ANALOG, OUT_DIGITAL, OUT_RELAY_LP, OUT_BLIND⁽¹⁾	OUT_ANALOG	OAnalog output, 0-10V, suitable to control the 0-10V or 1-10V input of another electronic board (dimmer, heat pump, linear valve, ...). Optionally it's possible to configure this port as open-drain output 40V 100mA max, that can be connected to external leds or relay by using the optional 5-wires cable: od2 pcb jumper must be shorted, in this case.
6	IO1	IN_DIGITAL, IN_ANALOG, IN_TWINBUTTON, IN_COUNTER, OUT_DIGITAL, OUT_BLIND, OUT_DIMMER, OUT_BUZZER	IN_DIGITAL	Analog/digital input that can be used to read voltages, or can be connected to contact, switch, magnetic sensor, PIR, ... It can be configured as counter and connected to energy/gas/water meter. It can be configured as IN_TWINBUTTON (that can be connected to a double pushbutton) by shorting the PCB jumper RU1, or 10mA OUTPUT by shorting the PCB jumper RO1: in the latter case, it can be used as a low current 3V output, connected to buzzer or to a relay board within the coil driver.
7	IO2	IN_DIGITAL, IN_ANALOG, IN_TWINBUTTON, IN_COUNTER, OUT_DIGITAL, OUT_BLIND⁽¹⁾, OUT_DIMMER, OUT_BUZZER	IN_DIGITAL	Analog/digital input that can be used to read voltages, or can be connected to contact, switch, magnetic sensor, PIR, ... It can be configured as counter and connected to energy/gas/water meter. It can be configured as IN_TWINBUTTON (that can be connected to a double pushbutton) by shorting the PCB jumper RU2, or 10mA OUTPUT by shorting the PCB jumper RO2: in the latter case, it can be used as a low current 3V output, connected to buzzer or to a relay board within the coil driver.
8	IN1	IN_AC	IN_AC, IN_COUNTER	Low voltage input, 9-40V AC or DC, opto-isolated. Suitable to sense the presence of voltage
9	IN2	IN_AC	IN_AC, IN_COUNTER	Low voltage input, 9-40V AC or DC, opto-isolated. Suitable to sense the presence of voltage
10	IN3	IN_AC	IN_AC, IN_COUNTER	230V input, opto-isolated. Suitable to sense the presence of voltage, and detect power-outage (blackout)

(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.

Application notes

Dimming 1 led stripe by internal Mosfet 24V 12A, + 2 led stripes using external controller

DomBus23 module can be interface with Domoticz and, using the internal mosfet with 30V 12A, can internally regulate the brightness of a led stripe.
Also, DomBus23 has 2 analog outputs 0-10V that permit to control 2 additional led stripes by an external led dimmer.
