AC Analog
Inputs
The D25 accepts up to 15 AC analog inputs, which are grouped into five sets
of three each.
The D25 can support virtually any combination of CTs and PTs.
The only restrictions are:
• TB1 inputs must be PTs
• Each group of 3 transformers must be of the same type
If no AC inputs are specified, AC Input configuration is disabled.
Disabled parameters appear in dark green in the SGConfig I/O Configuration
window

configured as
PT inputs
When configuring a D25 device with all AC inputs configured as PT inputs,
add a CT input to the AC Circuit and set up as “voltage circuit only”. See the
D25 AC Configuration properties > Circuits tab > Circuit 1 Properties >
Voltage Only Circuit check-box in SGConfig.

Circuit
Mapping
A flexible AC input mapping feature, called E-Z Map, is included.
• It allows you to configure, for each input of an AC circuit, the physical AC input
that supplies the required signal.
• It gives you complete flexibility in wiring the AC inputs and assigning them to
the appropriate circuit inputs.
