RTU2020 Remote Terminal Unit Overview
The RTU2020 is a modular, powerful and scalable controller capable of all remote automation and control applications. It is designed to communicate with any SCADA system but when combined with Experion® PKS and its radically simplified SCADA configuration with superior operator experience, it solves the most challenging remote automation requirements for the Oil & Gas industry.
The key features of the RTU2020 include:
Lowest power consumption in its category at a typical 1.8W
Temperature range -40 to 75°C (-40 to 167°F). Up to 75°C, not 70°C like other units
High reliability with well designed thermal paths
HART enabled onboard I/O onboard. No extra hardware required. Digital HART data & diagnostics are available locally for use in RTU program & remote alarming
HART IP allowing remote asset management of HART devices via Honeywell’s Field Device Manager
Efficient wiring & configuration saving installation and maintenance time
Modern, powerful CPU
Transient Suppression on every I/O channel & every communication port
RTU Builder: A powerful IEC 61131-3 programming environment
Liquids & Gas calculations in the same controller
Flexible communication options
Industry standard protocols of Modbus & DNP3 both as master and slave

Definitions
IOTA, Input Output Termination Assembly: An assembly that holds the IOM and the connections for field wiring
IOM, Input Output Module: A device that contains most of the electronics required to perform a specific I/O function. The IOM plugs onto the IOTA.
CPM, Control Processor Module: A device that contains most of the electronics required to perform the function of an RTU controller. A CPM plugs onto an IOTA designed for the CPM. The CPM may optionally include the functionality of an IOM.
Specifications
RTU2020 Controller
The RTU2020 family has an innovative modular hardware design with processor modules that plug onto IOTAs that contain only passive devices such as cable connectors and an I/O link expansion port allowing expansion I/O modules to connect in without any further infrastructure.

Performance
With a modern dual core 667MHz processor, RTU2020 has the power for today’s applications and spare reserve to meet tomorrow’s needs.
Communication Capabilities
RTUs need to efficiently manage unreliable, low bandwidth networks. They need to communicate as a slave device to a remote SCADA system, usually over a redundant link which is on two different mediums; but also as a master to local subsystems like gas chromatographs and smart drives. RTU2020 covers all the scenarios by supporting SCADA protocols such as Modbus and DNP3 over two Ethernet ports and four serial ports.
