1）對(duì)于繼電器這類電感性負(fù)載，必須安裝火花抑制器。
2）對(duì)于容性負(fù)載，應(yīng)在信號(hào)輸出負(fù)載線路中串聯(lián)限流電阻。電阻阻值應(yīng)確保負(fù)載承受的瞬時(shí)電流和電壓被限制在額定值內(nèi)。
3）在用晶體管輸出直接驅(qū)動(dòng)指示燈時(shí)，沖擊電流可能損壞晶體管。為此應(yīng)設(shè)置保護(hù)電阻以防晶體管被擊穿。
4）當(dāng)被驅(qū)動(dòng)負(fù)載是電磁開關(guān)、電磁離合器、電磁閥線圈等交流負(fù)載，或雖是直流負(fù)載，但工作電壓或工作電流超過(guò)輸出信號(hào)的工作范圍時(shí)，應(yīng)先用輸出信號(hào)驅(qū)動(dòng)小型中間繼電器（一般工作電壓＋24V），然后用它們的觸點(diǎn)接通強(qiáng)電線路的功率繼電器或直接去激勵(lì)這些負(fù)載（見圖1）。當(dāng)然，如果所用PLC裝置本身具有交流輸入、輸出信號(hào)接口，或有用于直流大負(fù)載驅(qū)動(dòng)的專用接口時(shí)，輸出信號(hào)就不必經(jīng)中間繼電器過(guò)渡，即可以直接驅(qū)動(dòng)負(fù)載器件。
