This is a Four Channel relay that can be triggered by the MTT Precision Detector. It comes with an adapter to connect the Precision Detector directly to the relay. It uses 12V power supply(so does the detector) so we recommend our 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.
** 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.
