Orion I/O

The Least Expensive, Most Dense, Easiest to Configure and Best-Looking Substation I/O Yet

Orion I/O is designed for high performance 12V dc to 125V dc monitoring and control applications in electrical substations including 1ms SOE Recording, circuit breaker TRIP/CLOSE, higher-speed control, and analog transducer monitoring and measurement. Although Orion I/O can stand-alone and operate as an independent RTU, it is usually connected serially or with Ethernet to an OrionLX™ or other substation RTU.

The 16-Point Discrete Input Card in Orion I/O monitors the position, status, or health of substation apparatus such as circuit breakers, reclosers, transformers, tap changers, and capacitor banks. The 16-Point Discrete Output Card energizes TRIP and CLOSE coils in circuit breakers and reclosers, or switches other loads. The 8-Point Analog Input Card monitors and measures transducers signals representing amps, volts, watts, vars, frequency, etc.

NovaTech Orion I/O™ is an extension of the family of OrionLX™ Automation Platforms for substation automation and incorporates the same security features, software tools and “NCD” configuration as the OrionLX. It is a rack-mountable I/O assembly with four slots—A, B, C, and D—that can be filled with any combination of I/O cards: currently 16-Point Discrete Input Card, 16-Point Wetted Discrete Input Card, 16-Point Discrete Output Card, and 8-Point Analog Input Card. Full population of discrete cards yields 64 I/O in 2 RU (rack units); full population of analog input cards yields 32 analog inputs. See Figure 1 below for rear connections on Orion I/O.


Advanced User Interface


This optional front panel provides the following data at the touch of a button in an interface of a similar design to the Bitronics® 50 Series and 60 Series metering products:

  • Input and output status
  • Point name (default assigned point name or Alias name)
  • Discrete point state (e.g. “Open”, “ON”, etc) and the timepoint last changed
  • The I/O cards in slots A, B, C and D in Orion I/O module
  • The name of the Active NCD file and firmware version
  • User-defined message
  • Time diagnostics

A standard, conventional faceplate is also available.

Some available status and diagnostic displays:


I/O Cards

Four Orion I/O Cards are available:

  • 1ms SOE Card with 16 inputs. High range (125V dc) or low range (12-48V dc) selection in software.
  • 1ms SOE Card with 16 wetted inputs. 24V dc or 48V dc sourced directly from card, and selected in software.
  • Output Card with 16 relay-grade outputs, ordered normally open (NO) or normally closed (NC)
  • Analog Input Card with eight inputs of -2 to +2mA, 4-20mA, or -10V to +10V

Any combination of the four above I/O cards can be ordered in the four-slot, 2 RU chassis

Ethernet Ports, Serial Ports, and IRIG-B

Orion I/O provides two copper Ethernet ports (separate NICs). In Phase 2, two LC fiber ports with separate NICs will be optional, as will be copper and LC fiber switch options (one NIC, two ports). A PRP/HSR redundancy option will also be available.

Orion I/O is also available with one RS-232/485 serial port. Webpage software provides selections for full or half duplex, and termination resistor. IRIG-B can be received from an OrionLX RTU on RS-485 terminals. A second serial ST fiber port will be available in Phase 2.

Screw terminals are provided to accept unmodulated IRIG-B. Precision Time Protocol (PTP) will be available in Phase 2. The image below shows Ethernet ports, communication ports, a serial port terminal, power terminals, alarm terminals, and IRIG-B terminals.


Cyber Security

Orion I/O offers the same suite of security features as the OrionLX, including:
  • Linux operating system
  • Trusted Platform using Secure Boot for Whitelisting
  • Secure protocols: HTTPS, SSH, SFTP
  • Strong passwords and password rules
  • Remote Authentication with LDAP
  • User Groups with specific administer-assigned privileges
  • Built-in Firewall
  • Automatic backup of complete Orion I/O configurations
  • Security event logging with “Syslog”

Security Monitoring Points indicating who is connected (by username) and how they are connected (HTTPS, Front Port, SSH, etc.). These points can be mapped to SCADA or to an alarm log.


Communication Protocols, Math and Logic and Software Options

Orion I/O supports all common “Slave” and “Server” protocols including DNP3, 61850, IEC 60870 and Modbus. Orion I/O also supports IEC 61131-3 Math & Logic, Alarm Annunciation, and SOE software options. For complete details, see Orion I/O Model # Builder below
