This is a Eight Channel relay that can be triggered by the MTT Precision Detector. It needs a 5V power supply(so does the detector) so we recommend our 5V Power Module.
The switch side of the relay has both Normally Open and Normally Closed connections, plus a common. You can switch up to 8Amp/125VAC or 28VDC.
You can buy this item separately or you can buy the Relay, 5V Power Module and the MTT Precision Detector as a KIT.
** We DO NOT make this relay and it is readily available elsewhere. We provide it for sale as a convenience and we don’t make a profit. However we tested this one for compatibility so we know it works.
