8 Channel USB Relay Board W/IO and DC Power Terminal Block


8 channel USB relay board with heavy duty 10 Amp 250VAC/28VDC SPDT general purpose/power relays, controlled through one of the PC USB ports.

Includes 8 channel TTL compatable input/output port individual channel selectable in setup program.

Designed for single board operation or multiple board operation by adding RS232 units to the output on the USB relay board. Up to 16 boards can be connected in a daisy chain configuration, with up to a total of 128 - 10 Amp relays under computer control, on one USB port. See example below:

With DC Terminal Block power input - typically used when a regulated DC power supply with sufficient capability is already available where the unit will mount, or to daisy chain units on one power supply. Requires a regulated voltage between 9-12VDC @ 1Amp per board. Includes reverse voltage protection to prevent damage to the board if the power leads were installed backwards.

• ASCII commands to control relays.
• Easy hook up using USB cable.
• Any software language that can write to the PC serial port can be used with this relay board, since the USB driver creates a virtual COM port.
