EasyLogic RP-IO

 
action_zoom_plus_stroke RP-IO-16E-M-24V

RP-IO-16E-M-24V

Introduction

EasyLogic™ 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 has the following features:

  • Native BACnet MS/TP support

  • Full range of I/O module models

  • Versatile onboard I/O point mix

  • Built-in isolated power supply

  • Optional covers

  • Advanced monitoring

  • EasyLogic living space sensors

  • Full EcoStruxure Building Operation software support, providing efficient engineering tools

A maximum of three RP-IO modules can be used with an RP or MP controller. For more information, see the Architectural Guidelines.

Native BACnet MS/TP support

The EasyLogic range of RP and MP controllers and RP-IO I/O modules natively communicate with automation servers and field devices using the BACnet MS/TP protocol.

The RS-485 port with 3-pole screw terminal block is used for connection to the BACnet MS/TP network.

Full range of I/O module models

The EasyLogic RP-IO range of BACnet MS/TP based I/O modules includes two different models, which offer two different sets of I/O point types, named 12A and 16E. The two models support 24 VAC/DC power supply.

Models with a versatile mix of I/O points

The RP-IO-12A and -16E 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.

Universal inputs/outputs

The universal inputs/outputs are ideal for any mix of temperature, pressure, flow, status points, and similar point types in a building control system.

As counter inputs, the universal inputs/outputs are commonly used in energy metering applications. As supervised inputs, they are used for security applications where it is critical to know whether or not a wire has been cut or shorted. These events provide a separate indication of alarms and events in the system.

For all analog inputs, maximum and minimum levels can be defined to automatically detect over-range and under-range values.

The universal inputs/outputs are capable of supporting analog outputs of type voltage outputs. Therefore, the universal inputs/outputs support a wide range of devices, such as actuators.

Only devices with safe extra low voltage equipment (SELV/PELV) inputs/outputs should be connected to the universal inputs/outputs.

Solid-state relay outputs

The solid-state relay (SSR) outputs can be used in many applications to switch 24 VAC or 24 VDC on or off for external loads such as actuators, relays, or indicators. SSRs are silent and are not adversely affected by relay contact wear.

Built-in isolated power supply

The device has a built-in power supply designed to accommodate 24 VAC or 24 VDC input power. The AC/DC power input is galvanically isolated from the electronics. This minimizes the risk of damage due to earth currents and permits the input power to be wired without concern for AC polarity matching. With the isolated AC/DC power input, you can use a central transformer for many devices, instead of one transformer for each device, to reduce installation costs.

Optional covers

All RP-IO models can be equipped with optional covers to reduce access to the screw terminals and wires.

Advanced monitoring

The I/O module supports local trends and alarms, enabling local operation when the I/O module is offline.

With user-defined fallback values, the I/O module outputs will be in a predictable state in cases of network disruption.

The battery-free power backup of the memory helps prevent data loss and allows seamless and quick recovery after a power disruption.

In WorkStation, you update the firmware of multiple I/O modules at the same time and with minimum down time. The EcoStruxure BMS server keeps track of the installed firmware to support backup, restore, and replacement of the I/O modules. The server can host I/O modules of different firmware versions.

EasyLogic living space sensors

The EasyLogic Sensor provides a cost-effective solution to measure, control, and communicate the temperature. The sensors are connected to analog inputs of the RP or MP controller. The EasyLogic Sensor is available in two models with different user interfaces, a blank cover or an LCD display with buttons for setpoint control. For more information, see the EasyLogic Sensors - Temperature Sensors – Analog - Specification Sheet.

Full EcoStruxure Building Operation software support

The power of the I/O module is fully realized when it is part of an EcoStruxure BMS, which provides the following benefits:

  • WorkStation/WebStation interface

  • Device discovery

  • Engineering efficiency

WorkStation/WebStation interface

WorkStation and WebStation provide a consistent user experience regardless of which EcoStruxure BMS server the user is logged on to. The user can log on to the parent EcoStruxure BMS server to engineer, commission, supervise, and monitor the I/O modules and RP and MP controllers. For more information, see the WorkStation and WebStation specification sheets.

Device discovery

The enhanced Device Discovery in WorkStation enables you to easily identify the I/O modules on a BACnet network and to associate the I/O modules with their parent server.

Engineering efficiency

The engineering and maintenance of the I/O modules can be done very efficiently using the EcoStruxure Building Operation reusability features. With these features, you can create library items (Custom Types) for a complete I/O module application that contains I/O point configurations and all necessary objects such as trends and alarms. The I/O module application in the Custom Types library is reusable across all I/O modules of the same model. You can use the I/O module application as a base for creating new I/O modules intended for similar applications. You can then edit the I/O module application, and the changes are automatically replicated to all I/O modules, while each I/O module keeps its local values.

WorkStation supports both online and offline engineering of the I/O modules. You can make the configuration changes online or use database mode to make the changes offline. In database mode, the changes are saved to the EcoStruxure Building Operation database so that you can apply the changes to the I/O modules later.

Project Configuration Tool enables you to perform all the engineering off site, without the need for physical hardware, which minimizes the time you need to spend on site. You can run the EcoStruxure BMS servers virtually and engineer the RP and MP controllers and the I/O modules before you deploy your server, controller, and I/O module applications to the servers, controllers, and I/O modules on site. For more information, see the Project Configuration Tool specification sheet.
