Atom Extension Modbus RTU

Used to integrate third-party devices via the Modbus protocol. This enables you to build a comprehensive automation system using your existing equipment or devices that best fit your requirements.

1. 12-24V DCPower supply

2. CAN bus ensures synchronized operationof all Atom series devices

3. Device status indicator

4. RS-485 interfacefor integrating third-party devices

Note : Technical specifications, wiring diagrams, input and output specifications and other technical information can be viewed on page Atom Modbus RTU

Important! During installation and operation, observe the general rules of electrical safety regarding the use of electrical appliances, as well as the requirements of regulations on electrical safety. It is strictly forbidden to disassemble a device to which any conductors are connected!
Before connecting sensors or other devices, make sure that the controller is turned off and not powered.

Important! Although the controller has built-in protection against incorrect power connection, and in this situation will not fail, we recommend that you pay attention to the correct polarity when connecting

If your system uses multiple controllers, connect them to a i3-NET network. Install the end terminators included in the equipment kit at the ends of the bus.

4. Connecting devices

Devices on the RS-485 bus are connected to the controller using twisted pair cable, which significantly improves noise immunity and is a mandatory requirement for connecting all devices operating via the Modbus protocol. Using twisted pair allows creating lines up to 1200 meters long, which practically satisfies all home automation needs. It is also important to ensure sufficient distance between data cables and power cables. Shielded cable is often used to improve noise immunity.
A mandatory condition for reliable operation of the RS-485 interface, according to the standard, is the presence of termination resistors at both ends of the bus. These resistors are included in the supply kit of Atom controllers.
The bus topology is linear, with minimal branch length for connecting peripheral devices.
