Integrated Analog to Digital Converters may be used to manually control the relays, or they may be used to read external sensors.
Equipped with your choice of 1, 2, 4, or 8 on-board relays, the ProXR Lite series USB Relays suit the needs of most of our customers. NCD ProXR Lite series controllers are a widely adopted standard used by industry for many years. USB Relay boards allow you turn relays on or off, flash relays continuously, control relays for a duration of time, and control relays in groups using a cross-platform compatible USB interface.
Our USB Relay products make it easy for computers of all types to control relays and monitor analog inputs.
