RTU38 Advanced Rooftop Controller

The RTU38 is a 38-point rooftop controller with dual Ethernet ports and an isolated MS/TP port that provides BACnet/IP and BACnet MS/TP client/server capability. A powerful CPU with a Linux OS makes this an ideal controller for OEMs who want to develop custom equipment for applications, such as economizers, demand control ventilation, variable air volume control, and multi-stage heating and cooling.

Application Ready Platforms

The APPI Series is built upon the high-speed Raspberry Pi Compute Module 3+ and includes two isolated EIA-485 serial ports suitable for BACnet MS/TP, Modbus RTU, or other serial protocols. Two non-switched Ethernet ports, each with its own MAC address, allow the platform to operate on two networks at the same time. A powerful CPU running a Linux OS makes these units accommodate the most demanding software applications. For wide-temperature operation, the APTI model offers operation from -40°C to +75°C. Both models—APPI and APTI—are FCC, FE, and EMC compliant and can be configured with an optional daughterboard to provide Wi-Fi, LTE/4G, or EnOcean wireless communication.
