产品总览: H System switch amplifiers from Pepperl+Fuchs consist of three primary components: the power supply, the transistor switch amplifier and the output stage. Galvanic isolation separates the input, output and power supply circuits. ( NAMUR ). This means the residual voltage in normal operation is approximately 8 VDC and the short circuit current is approximately 8 mA. The switch points are typically between 1.2-2.1 mA. Many Pepperl+Fuchs isolators offer optional lead breakage and
