Oak USB 4 Channel Relay Output (V1.2a)

Embedded USB Relay Output Card

The Oak Relay is a USB attached relay output card with 4 independent channels. It is designed to be used for 24V applications but can also be used to switch any voltage up to 30V DC and 120V AC.

All channels are electrically isolated from each other as well as from the USB circuit. Every channel can be used as normally-open contact, normally-closed contact or as change-over contact. To simplify installation, each Oak Relay output channel has disconnectable interfaces. The mating connector features screw terminals to allow a quick attachment of bare wires.

The relays can be switched with a maximum USB latency of 1ms. The report rate for reading the state of the relays is user adjustable from 1ms to 65s.

The Oak Relay can be integrated in a custom application very easily. The operating power as well
as real time relay switch instructions and uncritical device configuration data are all transferred
through a simple USB cable. The low power consumption, including automatic entering into sleep
