PR205 is a new programmable relay with graphic display and Ethernet. The device combines the optimal configuration of analog and discrete inputs/outputs for controlling ventilation, heating, air conditioning systems, etc. If necessary, the number of inputs/outputs can be increased using PRM expansion modules.

The graphic color screen allows you to create convenient and visual user interfaces, which greatly simplifies configuration and perception of information.

The Ethernet interface allows you to integrate the device into distributed systems, increase the number of inputs/outputs using Mx210 input/output modules, and implement remote control and management of equipment using the OwenCloud cloud service. The PR205 provides modifications with 2 RS-485 interfaces on board for transmitting data to the upper level and controlling other elements of the system.

The PR205 operating algorithm is built by the user in the free Owen Logic programming environment . This allows you to create unique custom algorithms and take into account all the features of the system.

Communication capabilities

  • Direct access to the OwenCloud cloud service.
  • Connection to a PC for configuring and recording the program.
  • Configuration in OWEN Configurator.
  • Visualization of processes using operator panels and SCADA.
  • Increasing inputs/outputs using Mx210 modules.
• Up to 2 RS-485 interfaces, Master/Slave mode, Modbus RTU/ASCII:
  • Integration into SCADA systems.

Optimal combination of inputs/outputs

• 4 analog inputs: PT1000, NTC/PTC, 4…20 mA/ 0…10 V, discrete mode.
• 3 universal analogue outputs: 4…20 mA/0…10 V.
• 6 discrete inputs (power supply = 24 V).
• 2 fast discrete inputs up to 100 kHz.
• 8 discrete outputs (E/M relays and transistor switches).
