General purpose RS232 serial port IO controller board with 8 relay outputs and 4 opto-isolated inputs for use in a wide variety of control and sensing applications including load switching, external switch input sensing, contact closure and external voltage sensing.Features
All components provided including a high quality case with pre-punched and silk screened front and rear panels to give the kit a professional and attractive finish as shown in the photos. High quality DS PTH PCB.
* The relays are rated to switch up to 240Vac mains voltage but the exposed screw terminal block heads would need to be placed inside a suitable enclosure to prevent exposure to hazardous voltages.Specifications
