EXAMPLE 1.1 SEL-701 Relay Part Number Creation
The part number 0701001X describes an SEL-701 Relay equipped
without internal RTD inputs and with ac voltage inputs.
All SEL-701 Relays are equipped with 1 A and 5 A nominal CT inputs, a broad
operating range power supply (20–250 ±20% Vdc <15 VA or 95–240 ±10% Vac
50/60 Hz), a single analog current output with settable range, six (6) self-wetted
contact inputs, and four (4) programmable form-C contact outputs. Refer to the
Specifications on page 1.11 for more product operating range information.
