Orion I/O™ for Electric Substations NovaTech Orion I/O™ is an extension of the family of Orion Automation Platforms for substation automation and incorporates the same security features, software tools, and NCD configuration as the OrionLX+, OrionLXm, OrionMX, and OrionSX. It is a rack, panel, or DIN rail mountable assembly with four slots that can be filled with any combination of I/O cards, currently: • 16-point Discrete Input Card • 16-point Discrete Input Wetted Card • 16-point Discrete Output Card • 16-point High Power Output Card • 8-point Discrete Input / 8-point High Power Output Combination Card • 8-point Analog Input Card • 8-point Analog Input Flex 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 front indications and rear connections on Orion I/O. I/O Cards Power Supply Terminals Ethernet Ports Figure 1 – Front indications and rear connections on Orion I/O with Advanced UI option 16-point Discrete Input Card • Electrically isolated circuits; two wires per input • Single design accommodates either higher voltage range (“HV”) or lower voltage range (“LV”). Range selection in software. • HV: nominal 125V dc, maximum 145V dc, always OFF at 75V dc • LV: nominal 12V dc to 48V dc, maximum 60V dc, always OFF at 9V dc 16-point High Power Output Card • Up to 145V dc • Break inductive circuit of 10A, with a time constant of 40ms L/R • OFF-to-ON, less than 10ms; ON-to-OFF, less than 10ms • Leakage current 1mA or less • Make 30A, continuous carry 10A • DC only 16-point Discrete Input Wetted Card • Module generates and sources the contact wetting current • 16 points in one group. Even-numbered terminals shorted together internally to provide more wiring flexibility. • 24V dc or 48V dc wetting voltage is provided by I/O card. Wetting power supply voltage software selectable in NCD. 8-point Discrete Input / 8-point High Power Output Combination Card • Input circuit and output circuit specifications as in above cards • Includes “Feedback Dropout” feature where the turn OFF of a selected output is gated by a state change of a selected input (e.g. 52a or 52b) 16-point Discrete Output Card • Conventional isolated normally open (NO) contacts • Two terminals per output • Tripping duty, substation-grade relay outputs » Make 30A, continuous carry 10A » Break inductive @48V dc: 700mA @40ms L/R Break inductive @125V dc: 200mA @40ms L/R • AC rating: up to 250V ac @8A 8-point Analog Input Card • Isolated with three ranges: -2mA to +2mA | -10V to +10V | 4mA to 20mA 8-point Analog Input Flex Card • Isolated with three ranges (as above): -2mA to +2mA | -10V to +10V | 4mA to 20mA • Range selection in software • Input impedance on voltages increased to 1M ohms (fro

Rear Display / Surface Mount To facilitate legacy RTU retrofits, a "Rear Display" (RD) model with panel and rack mounting options is available. All LEDs and ports are located on the same side. Security In addition to TPM (Trusted Platform Module), Orion I/O incorporates the same software tools and security features as all Orions, including support for RADIUS, LDAP, DNP3-SA, and TLS encryption.
