Relay yɛ voltage-type control device, ɛlɛtrɔnik switch a ɛde current ketewa bi di dwuma de hwɛ current kɛseɛ so. Ne adwuma titiriw ne sɛ ɛbɛtew control circuit no afi load circuit no ho.
Sɛnea ɛbɛyɛ a wobɛte dwuma a relay di ase yiye no, wubetumi asusuw ho sɛ ɛyɛ automatic switch a "ɛkyerɛ current kɛse bi a ɛde current ketewaa bi kyerɛ." Relay te sɛ "apon ano hwɛfo" wɔ ɔmansin bi mu; sɛ wo nsa ka ahyɛde bi (te sɛ bɔtn a wobɛmia anaa sensor sɛnkyerɛnne) a, ɛde ne ho bata anaasɛ ɛtwa mfiri a ahoɔden kɛse-wɔ mu.
1. High-Efficiency Conversion: Amansan tumi relays de electromagnetic nsakrae mfiridwuma a ɛkɔ anim di dwuma, na ɛma wotumi di tumi a etu mpɔn a ahoɔden a wɔde di dwuma kakraa bi. Wei kyerε sε ofie mfiri tumi de ahoɔden pii-yε adwuma yie, na εma ofie anyinam ahoɔden ho ka so tew.
