Additional specifications and description

 
Universal HVAC controller
The DRPUM is a versatile programmable controller designed for specific applications, requiring dedicated firmware. It incorporates two RJ45 sockets, one for Power over Modbus supply and another for connecting slave devices. Additionally, it is equipped with two RJ12 sockets exclusively for slave devices. The built-in Modbus RTU communication enables seamless control of various Sentera HVAC sensors and/or fan speed controllers through this device. Through the use of splitters, it is possible to connect up to 247 slave devices, providing a comprehensive and flexible solution for HVAC electronics applications.
This controller requires application dedicated firmware. Via an internet gateway, the controller can be connected to SenteraWeb - the online HVAC portal. Via SenteraWeb, you can select the desired application and download the application specific firmware into the connected devices.

Modbus RTU Master device 
A Modbus RTU Master device serves as a centralized controller in a Modbus network, managing communication with connected slave devices. The DRPUM being a master plays a pivotal role in managing the operation and data exchange between sensors and fan speed controllers. With its dedicated functionality the DRPUM enhances the efficiency and coordination of various components, contributing to the overall effectiveness of the HVAC electronics setup. Typically, the slave devices are Sentera’s HVAC sensors. They measure the environmental parameters and based on the measured values the HVAC system is controlled using Sentera’s 3SModbus software for setting and monitoring the parameters. 
This can also be done online via SenteraWeb using a Sentera Internet Gateway. That is how you can adjust and monitor your HVAC system from any part of the world.

Power over Modbus
The incorporation of Power over Modbus is a significant advancement in simplifying the connectivity and power distribution for HVAC electronics. Through the RJ45 and RJ12 sockets, both Modbus RTU communication and supply voltage are efficiently distributed to the connected devices.
Utilizing the RJ45 sockets, a 24 VDC supply voltage is seamlessly distributed, providing ample power for connected devices in the network. The use of RJ45 connectors is commonly associated with Ethernet connections. HVAC professionals are accustomed to working with RJ45 connectors, further simplifying the installation process. The use of 24 VDC in HVAC systems has become an industry standard. Many HVAC components, such as HVAC sensors and other devices are designed to operate optimally with this voltage, ensuring compatibility and reducing the risk of operational issues.
Similarly, the RJ12 sockets facilitate the distribution of 3,3 VDC supply voltage. This innovative approach enables the consolidation of communication and power distribution through a single cable, streamlining the installation process and reducing overall complexity. Sentera’s compact duct temperature sensors are supplied with 3,3 VDC.
