CT1S8工业自动化与控制的延时继电器规格书PDF中文资料

CT1S8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CT1S8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 CT Series combines a delay-on-make and delay-on-break

time delay into one unit and may be used to control fan delays

in heating and/or cooling equipment. The CT includes bypass

circuitry to allow it to operate with cooling anticipators ≥ 3000

ohms. It is designed to operate in 24VAC control circuits.

Several CT modules may be combined to provide sequencing of

any number of loads and sequencing off of the same loads, such

as electric heating elements.

Operation (Delay-on-Make/Delay-on-Break)

Forced Air Heating or Air Conditioning (as shown): When

the thermostat closes, the compressor relay is immediately

energized. At the end of a fixed delay-on-make delay (T1),

the fan relay is energized. When the thermostat opens, the

compressor relay is de-energized and the delay-on-break delay

is initiated. On completion of the fixed delay-on- break delay

(T2) the fan relay is de-energized. If the thermostat is reclosed

during the delay-on-break delay, the delay-on-break delay is reset

and the fan relay remains energized. If the thermostat is closed

when input voltage is applied, the delay-on-make delay (T1)

begins as normal.
