Digital outputs
For information about the digital outputs specifications, refer to Technical Specifications
Chapter.
The DR60 can work with up to 100% of its digital inputs and 50% of its digital outputs
energized simultaneously at the maximum ambient temperature (considering the
maximum number of inputs/output available).
Connections shall use screened/shielded cables with insulated flexible wires of 1.5 mm²
cross section, voltage rating of 300Vrms.
Each analog slot (E and H) provides 4 AC/DC current inputs (1 or 5 A) and 4 AC/DC
voltage inputs (115 V) or 4 DC transducer level voltage inputs (±10V) and 4 DC-
transducer level inputs (0-20mA).
All inputs are designated in DR60 software by their logical node name, as per IEC 61850
ed2. That means that the current inputs are names TCTR1 to TCTR16 and the voltage
inputs names are TVTR1 to TVTR16. Additionally, the input name contains a prefix that
associates the Slot the board is installed and the position of the input.
For example, the figure below show the analog inputs designations from TCTR1 to 4 and
TVTR1 to 4. In the DR Configurator tool, these inputs are named E1_TCTR1 to E4_TCTR4
and E5_TVTR1 to E8_TVTR4
The terminals in the position TVTR1, TVTR2 and TVTR3 share the same neutral, which is
connected internally.
