Onboard square USB interface connection stable. High-performance USB controller chip, military grade PCB board production. 12V relay, the relay can control the maximum 250V 10A AC load and 30V 10A DC load. Reserved 4, 8-way power interface, connected to power, even if the computer off or unplug the USB from the computer, you can also relay remains set. 1-way and 2-way no power connector. Control terminals Connection: NC / COM / NO. Voltage: DC 12V Load: 250V 10A AC / DC 30V 10A Max . Fixing hole size: 3mm. Mounting holes center distance: 52.2mm * 36.6mm. Support System: WIN7 / XP 32/64 bit systems. Size:71.6*65.3*20mm. * Windows software * PCB parameters: FR4 / 1.5mm / two layers / metalized holes / HAL / white stamp / solder mask. Application: Robotics control Home automation Control doors and windows via windows system Controller power supply Package included: 1 x 4 channels USB relay Note: * When the board is connected to the PC and the PC is restarted, the relays will be toggled several times. This is because of the structure of the FTDI chip. * The device must be supplied with 12V DC or order to work. * There is no protection against reversed voltage! If the VCC(+12V) and GND are reversed the board will be damaged! * The board can not work without computer. * If you need our software, please contact our customer service via email.
The module uses HID technology, without any driver, plug and play. Support WIN7, XP 32-bit, 64-bit system, easy to use simple. (Can provide development library, if you need, please contact us).
Onboard square USB interface, stable connection; use of high-performance USB control chip; use dedicated relay driver chip ULN2803, relay work more stable;
Power outlet and terminal, two access power mode convenient and flexible. After connecting the power, even if the computer shut down or USB from the computer pull out, the relay can also maintain the set state.
PCB size 71.6mm * 65.3mm, fixed hole size 3mm, fixed hole center moment 67.4mm * 61.3mm.
Note Due to the characteristics of the USB protocol, this module is not suitable for use where electromagnetic interference is large! If you want to use, please do electromagnetic shielding measures.
Not much instruction but you can figure it out by downloading the software via the link in their description.Works right out of the box, I bought a single channel and a four channel one, they both work great.Pros:- Easy setup- No need additional power supply for the single channel, you will need one with 4 channel or more as it needs more current to drive the relay.Cons:- Cannot use extra same units on the same system because the ID is the same. So for example, if you want to have two channels you cannot use two single channel ones because they have the same ID. You will have to buy a four channel one.- Does not come with the USB cable (its forgiven for the price).Notes:- If you plug in the system that does not recognize the USB HID device, in my case Embedded Windows XP, then you will need to install the driver for FTDI chip. The driver can be found here https://ftdichip.com/drivers/d2xx-drivers/. Note this one does not use the FTDI chip physically, however, they do mimic that of, probably running V-USB in the firmware.
