Description

The PLA143 is a single-pole, normally open (1-Form-A) solid state relay that uses optically coupled MOSFET technology to provide an enhanced input to output isolation of 4000Vrms.

Its optically coupled outputs, which use the patented OptoMOS architecture, are controlled by a highly efficient GaAIAs infrared LED.

The PLA143 can be used to replace mechanical relays, and offers the superior reliability associated with semiconductor devices. Because it has no moving parts, it offers faster, bounce-free switching in a more compact surface mount or thru-hole package.

PLA143属于继电器 > 固态继电器。IXYS Integrated Circuits Division制造生产的PLA143固态继电器固态继电器 (SSR) 是光隔离的电子开关器件，当在控制输入端子两端施加小电压时，这些器件会打开或关闭。SSR 与设计用于开关高达 660 V 的 AC 或 DC 负载的底座、DIN 导轨、插座和板安装式机电继电器相似，但基于半导体且没有活动部件。这些器件可根据负载电压、额定电流和开关电路配置（例如 SPST、SPDT、DPST 和 3PST）进行选择。
