The PXC series programmable controller is part of the APOGEE control system, is a high-performance direct digital controller, belongs to BACnet building-level controller (B-BC), and uses BACnet/IP protocol. The controller can independently run or network to perform complex control, monitoring and energy management functions without relying on more advanced processors.
The PXC series controllers are high‑performance direct digital controllers that support BACnet/IP and can operate independently or on a network for complex control, monitoring, and energy‑management tasks. They are suitable for indoor and outdoor installations, including rooftop HVAC units, and have passed BACnet testing laboratory certification.
Hardware includes a Motorola PowerPC MPC852T processor at 100 MHz, 16 MB RAM and 8 MB flash (24 MB total), and selectable 16‑ or 24‑point I/O modules with universal analog and digital capabilities. Power is supplied internally from 20‑30 Vac, providing 24 V DC to I/O points, and the controller communicates via BACnet/IP over 10/100 Mbps Ethernet, RS‑232, and a modem interface. The unit measures 10.7" L × 5.9" W × 2.45" H. This manual is written in Chinese.

It supports BACnet/IP over 10/100 Mbps Ethernet, as well as RS‑232 and a modem interface for remote access.
The PXC16 provides 16 I/O points (including 8 universal points) and the PXC24 provides 24 I/O points (including 16 universal points).
It requires an input of 20 Vac to 30 Vac at 50/60 Hz, and supplies 24 V DC internally for I/O and sensors.
The firmware and operating system are stored in non‑erasable ROM, and the ROM can be upgraded on site.
