Isolated Digital I/O Connections

LED Denitions

The USB Module is equipped with an LED indicator to

show the current status of the device. When you plug the

USB device into the USB port, the LED indicator will blink

five times and then stay lit to indicate that it is on. Please

refer to the following table for detailed LED indicator status

information

LED Status Description

ON Device ready to work

OFF Device not ready to work

Slow blinking (5 times) Device initializing

Fast Blinking Device working

Single-ended Channel Connections

USB-4761 has 8 isolated digital input channels. Each of

isolated digital input channel accepts 5~30 VDC voltage in-

puts, and accept bi-directional input. It means that you can

apply positive or negative voltage to an isolated input pin

(Vin ). The figure below shows how to connect an external

input source to one of the card's isolated input channels.

Relay Connections

After power on, the initial relay output status is shown as
