What is it?

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

Creasol DomBus36: 12 relays module for home automation systems. Supporting Modbus and DomBus protocls

Why did you make it?

Serving many outputs, controlling up to 144 bays locker (12x12) for express couriers, minimize power usage, simplify wirings

Features

• available in two firmware version, DomBus suitable for Domoticz controller, and Modbus suitable for any industrial and home automation system.
• 12 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).
• easy wiring: relays are divided in 3 groups, each group share a common with the 4 relays in that group.
• each relay block respects the creepage distance from other blocks. Do not mix high and low voltage signals inside the same block!
• 8-35Vdc power supply (internally regulated by a switching mode power supply circuitry that minimize power consumption and dissipation).
• low power consumption: 0.9mA @12V (12mW) stand-by current with all relays OFF, and 55mA @12V (<750mW) with all relays ON.
• 115200 bps RS485 bus (max length: 1km), 8 bit data, no parity, 1 stop bit. Bitrate and parity may be changed in the Modbus version.
• DCMD commands support (DomBus firmware only): this is a feature (described below) that permits to get easy automations without writing a line of code, and command exchanged between DomBus modules even in case that domotic controller is stopped. For example configuring a pushbutton input port as DCMD(Pulse)=11.3:Toggle, DCMD(Pulse1)=0.7:Toggle, DCMD(Pulse2)=0.8:On it's possible:
• with a short 0.5s pulse, toggles on/off port #3 output of DomBus module #11
• with a 1s pulse, toggle on/off a group of switches on the controller
• with a 2s long pulse, activate a scene that, for example, disable all lights/loads and activate the alarm system (useful when leaving the building).

What makes it special?

• Very low power usage, much lower than competitors
• Very high reliability
