The PR225 is a programmable relay in a panel enclosure with a graphic display and Ethernet that allows for user-friendly and clear user interfaces, which greatly simplifies setup and information comprehension. The device combines an optimal configuration of analog and discrete I/O for controlling ventilation, heating, air conditioning systems using the free ALP programming environment. Ethernet and RS-485 interfaces allow you to connect additional modules, output information to the upper level and control other elements of the system, as well as output information in akYtec cloud.
PR225 is a new programmable relay in a panel enclosure with a graphic display and Ethernet. The device combines an optimal configuration of analog and discrete inputs and outputs for control in water supply, heating, air conditioning, ventilation, food industry, and other systems.
The 3.5" color graphic screen allows you to create convenient and intuitive user interfaces, which greatly simplifies configuration and information perception. And mounting the device on the cabinet door does not require the use of an operator panel.
The Ethernet interface allows the device to be integrated into distributed systems, increase the number of inputs and outputs using Mx210 I/O modules, and remotely monitor and control equipment using the akYtec Cloud service. PR225 has 2 RS-485 interfaces. This allows the system to be expanded using Mx110 modules to control actuators or transfer data to the upper level.
The PR225's operating algorithm is built by the user in the absolutely free native programming environment akYtec ALP. This allows you to create unique user algorithms and take into account all the features of the system. This allows to create unique user algorithms and take into account all peculiarities of the system.
