i-Vu® MPC Open XP IO

High‑capacity I/O expansion for scalable MPC Open XP system control
The i‑Vu® MPC Open XP IO (OPN‑MPCXPIO816) expands the input and output capacity of MPC Open XP controllers, enabling efficient control of larger air‑side and water‑side HVAC systems while maintaining seamless integration with the Carrier i‑Vu® Building Automation System.

i-Vu® MPC Open XP IO

Multipurpose programmable controller for monitoring and control of HVAC system applications. Adds additional I/O point capacity to the OPN-MPCXP controller.
The MPC Open XP IO expanders add additional I/O point capacity to the MPC Open XP controller. Flexible and versatile, the MPC Open XP controller supports multiple I/O configurations for accomplishing both common and custom HVAC control strategies. The MPC Open XP controller connects to up to 20 field points directly (8 outputs and 12 inputs), while also supporting up to 3 MPCXP IO expanders. Each MPC XP IO48 expander adds support for up to 12 additional field points (4 outputs, 8 inputs), while each MPC XP IO816 expander adds support for up to 24 additional field points (8 outputs, 16 inputs). When combined, the MPC Open XP controller and it’s associated MPC XP IO expanders can support up to 92 total points.

What is the primary function of the MPC Open XP IO module?

It expands the I/O capacity of an MPC Open XP controller to support larger or more complex HVAC systems.

Can the expander be mounted directly on the controller?

Yes. The first MPC XPIO expander can be mounted directly on the MPC Open XP controller to save panel space.

Do the outputs support manual override?

Yes. Outputs include Hand‑Off‑Auto switches and potentiometers for manual control and testing.

Is the module suitable for retrofit projects?

Yes. Its flexible mounting and Xnet connectivity make it suitable for both new installations and retrofit expansions.
