繼電器輸出模塊優(yōu)點(diǎn)是適用電壓范圍寬,導(dǎo)通壓降損失小,價(jià)格便宜,缺點(diǎn)是壽命短,響應(yīng)速度慢。輸出模塊同時(shí)接通點(diǎn)數(shù)的電流累計(jì)值必須小于公共端所允許通過(guò)的電流值。輸出模塊的電流值必須大于負(fù)載電流的額定值。
6、結(jié)構(gòu)型式的考慮
PLC的結(jié)構(gòu)分為整體式和模塊式兩種。整體式結(jié)構(gòu)把PLC的I/O和CPU放在一塊大印刷電路板上,節(jié)省了插接環(huán)節(jié),結(jié)構(gòu)緊湊,體積小,每一I/O點(diǎn)的平均價(jià)格也比模塊式的便宜
