Description

The 4-channel Modbus – OpenTherm gateway is set up for mounting in the electrical panel box, on standard DIN rail (2 modules), and the power supply is 12 Vdc. The regulating system that the gateway is connected to must have Modbus RTU protocol (RS-485) with settable communication parameters (baud rate 9600 or 19200, parity even or none).

The slave address must be configured between 1 and 63.

The gateway is set up with 4 channels for communication through OpenTherm protocol with the same number of generators. All of the connections can be set up using removable terminals; plus, the connection is opto-isolated towards the generators.
