PVA3054NS数据手册继电器的固态继电器规格书PDF

描述 Description

300 V, 50 mA single-pole Photovoltaic Relay in a mod. 8-pin SMT Package. This normally open solid-state relay can replace electromechanical relays used for general purpose switching of analog signals. The PVA30 Series combines very low solid-state output capacitance, very high off-state resistance and very fast response times. These Photovoltaic Relays are designed specifically to accurately switch low-level signals in highperformanceinstrumentation systems. The PVA30 Series overcomes the limitations of both conventional electromechanical and reed relays by offering the solid state advantages of long life, fast operating speed, low pick up power, bounce-free operation, low thermal offset voltages and miniature package. These advantages allow product improvement and design innovations in many applications such as process control, multiplexing, automatic test equipment and data acquisition. The PVA30 can switch analog signals from thermocouple level to 300 Volts peak AC or DC polarity. Signal frequencies into the RF range are easily controlled and switching rates up to 1.7kHz are achievable. The extremely small thermally generated offset voltages allow increased measurement accuracies.

简介

PVA3054NS属于继电器的固态继电器。由制造生产的PVA3054NS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。
