Creasol DomBus37 is a DIN RAIL module, 115x90x40mm, supporting both DomBus and Modbus RTU protocols.

It can be connected to the home automation controller by a RS485 serial bus (4 wires, 2 for 12/24V power supply, and 2 for data at 115200bps).

As other DomBus devices, DomBus37 is designed to consume low power, be reliable, fully configurable and easy to use. Each input port is fully configurable, for example as analog or digital input, twinbutton (double button connected to a single port), counter, buzzer, NTC 10k, ... Analog ports are able to decode single, double, triple, quadruple balanced alarm sensors.

Features

1x 250V 10A relay with N.O. (SPST) connection, configurable in normal or low power mode, blind mode (UP/DOWN motor) and in flash mode (connected to a blinker lamp or siren)
2x 250V 5A relays with N.O. (SPST) connection, configurable in normal or low power mode, blind mode (UP/DOWN motor) and in flash mode (connected to a blinker lamp or siren)
12x configurable I/Os, each one can be set as digital input (with internal pullhigh, active low), digital input with pulldown (active high), analog input, twinbutton input (double pushbutton connected to a single module input), counter (energy meter, gas or water meter); an internal 10k pullup that can be activated by PCB jumper (for twinbutton and NTC10k sensors)
3x 115Vac / 230Vac optoisolated inputs, that can be used as digital input (to detect voltage on appliances, PIRs, and detect power outage) or counter (meter with AC output)
Optionally, activated by some PCB jumpers, it can supply an alarm siren monitoring the siren voltage, current and status / errors.
Monitor bus voltage
The 12 input ports are protected by clamping diodes and can operate between -40V and +40V.
9-35Vdc power supply (internally regulated by a high efficiency switching mode power supply circuitry that minimize power consumption and dissipation)
low power consumption: 12mW normally, 180mW with the 3 relays ON
115200 bps RS485 bus (max length: 1km)
DomBus proprietary protocol, working with Domoticz home automation system, or Modbus RTU standard protocol, working with Node-RED, Home Assistant, OpenHAB, and many other systems.

Warnings

Do not mix high and low voltage devices on relay outputs: relays may be used all connected to 115 / 230Vac devices, or all connected to 30Vmax devices.
Use a 4 wires shielded cable for the bus, using two lines to feed power supply (12 or 24Vdc) protected by a fuse.
To reduce noise and reflections on the bus, enable the termination resistor (shorting Rbus PCB jumper behind the LED) on the two furthest ends of the bus.
