Description

The SIR Series is designed for industrial applications requiring

rugged reliable operation. Provides an optically isolated, high

capacity, solid-state output, with power switching capability up

to 20A steady state, 200A inrush. Zero voltage switching SIR2

extends the life of an incandescent lamp up to 10 times. Random

switching SIR1 is ideal for inductive loads. When fully insulated

female terminals are used on the connection wires, the system

meets the requirements for touch-proof connections.

Operation

The solid-state output is located between terminals 1 and 3,

and is normally open or normally closed without control

voltage applied to terminals 4 and 5. When control voltage is

applied to terminals 4 and 5, the solid-state output opens or

closes respectively.

Reset: Removing control voltage resets the output. The unit is

also reset if output voltage is removed.

SIR2B20A4属于继电器 > 固态继电器。力特公司制造生产的SIR2B20A4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。
