HRDS430工业自动化与控制的延时继电器规格书PDF中文资料

HRDS430属于工业自动化与控制的延时继电器。由力特公司制造生产的HRDS430延时继电器延时继电器是使用较小控制信号启动或停止大负载的机电器件。这些器件内置有时间延迟来控制继电器的触发。功能包括间隔、关闭延迟、打开延迟、单次、可编程（多功能）、重复周期、双定时器、信号开/关延迟和 Star/Delta 控制器。

描述 Description

The HRDS Series combines an electromechanical relay output

with microcontroller timing circuitry. It offers 12 to 230V

operation in five options and factory fixed, onboard or external

adjustable time delays with a repeat accuracy of ±0.5. The

output contact rating allows for direct operation of heavy loads,

such as compressors, pumps, blower motors, heaters, etc. This

series is ideal for OEM applications where cost is a factor.

Operation (Single Shot)

Input voltage must be applied before and during timing. Upon

momentary or maintained closure of the initiate switch, the

output relay energizes for a measured interval of time. At the

end of the delay, the output de-energizes. Opening or reclosing

the initiate switch during timing has no affect on the time delay.

The output will energize if the initiate switch is closed when

input voltage is applied.

Reset: Reset occurs when the time delay is complete and the

initiate switch is opened. Loss of input voltage resets the time

delay and output.
