domotic module with 6 relays, 1 AC input, 12 low voltage inputs

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, DomBus38 is designed to consume low power, be reliable, fully configurable and easy to use.


Features

  • 4x 10A relays with both normally-open and normally-closed outputs on terminal block, configured in low-power mode (about 100mW/each, when On)
  • 2x 10A relays with normally-open outputs, configured in low-power mode (about 100mW/each, when On)
  • 1x AC optoisolated input to detect (and notify) power outages, implementing zero-crossing detection to permit relay switching minimizing the in-rush current (for capacitive loads, such as electronic boards) and overvoltage (for inductive current, like motors and coils).
  • 10x low voltage inputs with 10k pullup resistor that can be enabled by PCB jumper: can be connected to pushbuttons, switches, twinbuttons (up/down button connected to a single input), alarm sensors (magnetic contact, PIR, ...), counters and meters with pulsed output, NTC temperature sensors, ...
  • 2x low voltage inputs with internal pullup resistor that can be excluded in case of analog inputs: can be connected to pushbuttons, switches, alarm sensors  (magnetic contact, PIR, ...), counter and meters with pulsed output, analog voltages in the range 0÷3.3V.
  • Internal RS485 bus terminating resistor (150 ohm) that can be enabled by a PCB jumper (with a solder iron)
  • RS485 industrial bus, that works with up to 500m of cable (using standard alarm cable: 2x0.50+2x0.22mm² + shield)
  • DIN rail low-profile enclosure, 115x90x40mm, 220g
  • Plugin terminal blocks (disconnectable) for easy wiring
  • Available with 2 firmwares of your choice:
    • DomBus firmware, working with Domoticz, implementing the DomBus proprietary protocol
    • Modbus firmware, working with NodeRED, Home Assistant, OpenHAB and many other controllers supporting the standard Modbus protocol.
  • Very low power usage: 15mW with relays OFF.

Warnings

  • Do not mix high and low voltage devices on relay output blocks: relays may be used all connected to 115 / 230Vac devices, or all connected to 30Vmax devices within the same block. For example if RL1 is connected to 230V, RL2÷RL4 can be connected only to 230V loads, and low voltage devices can be connected only to RL5÷RL6, or vice versa. Of course, it's possible to connect all RL1÷RL6 to high voltage OR low voltage loads.
  • 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.

Smart-Home Creasol DomBus modules for Domoticz, Home Assistant, Node-RED, OpenHAB, ...

The following video shows a presentation of some domotic modules designed and produced in Italy by Creasol to make a reliable, easy and power-optimized home automation system.


The next video shows our Smart EVSE module that can be used to charge the electric car by using only solar power, or adding 25/50/75/100% of available power from the electrical grid.

Our industrial and home automation modules are designed to be

  • very low power (around 10mW with relays OFF)
  • reliable (no disconnections)
  • bus connected (no radiofrequency interference, no battery to replace).

Modules are available in two version:

  1. with DomBus proprietary protocol, working with Domoticz only
