As a liquid or solid rises or lowers around the probe, the capacitance field changes. This is monitored and used to control the two on-board relays. Each relay includes full differential control to ...

One is charged with handling the mains power side of things. It carries an SPDT relay for switching AC power, and a DC power supply to run the ESP32 itself. The controller board holds the ...

Nisshinbo Micro Devices has launched the NT1821 and NT1822 High Isolation SPDT Switches are engineered to meet the demands of ...

SPDT switches typically have three terminals which are commonly ... Contact choices for zero speed switches also include solid-state electronics, which replace mechanical relays and do not contain ...

Each reader node (input) provides (1) form C (SPDT) output relay for lock power switching, (1) dedicated request to exit input, (1) dedicated door position switch input, (2) auxiliary inputs, and (2) ...
