Power Supply Card
PSIO/2 DI/3 DO
(Slot A)
Select appropriate power supply option for the application:
➤ High Voltage: 110–250 Vdc, 110–240 Vac, 50/60 Hz
➤ Low Voltage: 24–48 Vdc
Select the appropriate digital input voltage option: 125 Vdc/Vac, 24 Vdc/Vac,
48 Vdc/Vac, 110 Vdc/Vac, 220 Vdc/Vac, or 250 Vdc/Vac.
This card is supported in Slot A of the SEL-751. It has two digital inputs and
three digital outputs (two normally open Form A contact outputs and one
Form C output). Table 2.1 shows the terminal designation for the
PSIO/2 DI/3 DO card.
