It designed to connect directly with 10PIN MRconnect . It is a quick and easy way to control up to 12A at The card can be power by using the 120VAC or 10A at 24VDC. power from the 10PIN MRconnect or external 2.5mm, center negative, 9- The relays required a very small current to 16VDC wall adapter or external power drive due to the on-board Darlington driver supply via the terminal block connector. circuit. Also, the driver pins are isolated from the relay driver circuitry. The diver The relay coil jumper need to be move to pins can be select from 4-bit HIGH or 4-bit the appropriate supply. Figure 1 show the LOW of the 10PIN MRconnect . Each of jumper selected power from the 10PIN the relay has an LED to indicate the state MRconnect . of the relay. The output terminals included COM (common), NO (normally open) and NC (normally close) contacts. The card can be power by using the power from the 10PIN MRconnect or external 2.5mm, FIG1: Power selection jumpers center negative, 9-16VDC wall adapter or external power supply via the terminal There are two options when using block connector. The board is small in external power supply. The external size 3.30 x 2.70 inches. supply can be from 2.5mm, center negative, 8-16VDC wall adapter via power jack or supply to terminal block.
