RP-IO Modules
The RP-IO module provides I/O expansion to your HVAC application over BACnet MS/TP. The I/O module can share its I/O resources across applications running in automation servers, RP and MP controllers, or third-party systems. With the support of local alarms and local trend logs, the I/O module avoids unnecessary traffic over the network while being able to log important information locally. The I/O module can be installed near facilities in the field, away from the automation server or the RP or MP controller.
The RP-IO module is an I/O module that allows for flexible control solutions due to the versatile mix of universal inputs/outputs and solid-state relay (SSR) outputs.
When RP-IO modules are part of an EcoStruxure BMS, you can take full advantage of the existing EcoStruxure Building Operation engineering tools.
RP-IO Models
The RP-IO module is available in two models that only support BACnet MS/TP communication. These two models offer two different combinations (sets) of the number and types of I/O points. Both models support 24 VAC/VDC input power.

RP-IO Onboard I/O
The RP-IO module models provide 12 or 16 I/O points, consisting of two different sets of I/O point types. The versatile mix of I/O point types match a wide variety of applications. The universal inputs/outputs are highly flexible and can be configured as either inputs or outputs.

RP-IO Module Built-in Power Supply
The RP-IO module has a built-in power supply designed to accommodate a nominal operating voltage of 24 VAC at 50/60 Hz or 24 to 30 VDC input power.

Memory in RP and MP Controllers and I/O Modules
RP and MP controllers and I/O modules are devices that have three types of memory:
Flash memory: for boot loader, operating system, application software, and configuration storage
RAM: for runtime operation
FRAM non-volatile memory: for data retention in the case of power outage

RP-IO Module Supported Building Standards
One of the cornerstones of the EcoStruxure BMS is support for open standards. As a result, the RP-IO module complies with the BACnet open standard, one of the most popular standards for buildings.

RP-IO Module Reset Modes
You can reset and restart the RP-IO module in different ways depending on how long you press the reset button. The resets and restarts can affect the retention of values after restart based on the retain levels configured for the variables.
