The MP-V and RP-V controllers use a digital pressure sensor to measure the air velocity pressure signal from the velocity probe in the inlet of the VAV box. The measured value is used by the controller to position the VAV damper actuator for the required air flow.
The RS-485 Power Adapter can be used to convert a BACnet/IP controller (RP or MP controller) RS-485 interface from RJ45 port to screw terminals, which is required to be able to connect the controller to an RS-485 based network such as a Modbus RTU network. The types of RS-485-based networks supported differ between the different RP and MP controller models.
This section provides recommendations on wire sizes and lengths for the RP-V controllers.
This section provides recommendations on minimum wire sizes (cross-sectional areas) and maximum wire lengths for the wires connected to the screw terminals of Central IO modules, AS-B servers, RP and MP controllers, and IP-IO modules. Recommendations on minimum wire size and maximum cable length for the digital inputs of the RP controller expansion modules, the DALI bus of the DALI light modules, the SMI Interface of the SMI blind modules, the Zigbee DALI and 0-10V modules, and the KNX Modbus gateway are also provided. The recommendations are for guidance only. Other wire sizes and lengths may be used, depending on wiring rules and when appropriate.
The RS-485 adapters are RJ45 to screw terminal block adapters and are offered as accessories for some BACnet/IP controller models when the controllers are used in certain network configurations.
The Status LED on the front of the automation devices changes color and flashes to indicate the status of the device.
There is one LED on the front panel of the RP-V.
You must configure the DIP switches as part of the commissioning process for RP controllers that support MS/TP communications.
One of the cornerstones of the EcoStruxure BMS is support for open standards. As a result, the RP and MP controllers comply with the BACnet open standard, one of the most popular standards for buildings.
