オプトカプラ(非売品) |

オプトカプラは入力回路と出力回路の2つの回路で構成されています。主要な入力部品は発光ダイオード(LED)であり、主要な出力部品は光検出器です。約10mAの電流を正しい極性で2つの入力端子から発光ダイオードに流すと、電流が光子に変換されます。すると光子は光伝達路へ向かい光伝達路の終わりで、光子を電流に戻す光検出器に入射します。このような方法で、入力情報は直接的な導電路がなくても転送され、出力検出回路で増幅されます。光伝達路が長くなればなるほど、金属の入力端子と出力端子との距離が大きくなります。これにより、より大きな絶縁抵抗と高い電圧絶縁を実現することができます。オプトカプラは危険な環境で使用することができ、ATEXの本質安全防爆構造要件を満たしています。当社のオプトカプラのラインは、ATEX(指令94/9/ECおよび1999/92/EC)の厳しい要件を満たすと認定された20,000 VDCの入出力絶縁を安全に処理することができます。この指令は、鉱業事業、可燃性ガス処理プラント、ESD(静電気放電)が大きな問題になる可能性のある医療用加工工場、および高絶縁と非アーク放電環境を必要とする工場など、爆発性雰囲気が存在する可能性のある工場で使用される機器および保護システムに適用されています。
