时间函数
时间继电器

C2和C3型工业继电器可通过时间模块改造成时间继电器。当获得具有所需时间功能的时间模块后，将其插入继电器与底座之间。

底座C12B0和CS-155（S5-M）配备有模块插槽，专用于时间模块/监控模块。因此，除了底座和工业继电器外，只需额外添加一个可插拔的时间模块即可。

几乎所有时间继电器的设置过程都相同。首先，通过电位器选择一个功能。每个字母（A、E、W、K 等）代表一个特定功能，该功能在继电器侧或随附说明书中有所描述。

接下来，选择时间范围，所选范围始终为最大值。最后，使用最后一个电位器进行时间微调。例如，要设置 30 秒的延迟关闭，操作如下：

功能：A

时间范围:60 秒

微调：在 0-6 的刻度上，将电位器调至 3（6= 60 秒,3 = 30 秒,1 = 10 秒）。

E – On delay

The function provides a delayed switching ON of the output.
When S switches ON, the time t starts.
After t expires, the output R switches ON.
If S switches OFF before t ends, R stays OFF.

A – Off delay

The function provides a delayed switching OFF of the output.
When S switches ON, the output R switches ON immediately.
When S switches OFF, the time t starts.
After t expires, the output R switches OFF.

F – On and off delay

The function provides a delayed switching ON and a delayed switching OFF of the output.
When S switches ON, the on delay t₁ starts.
After t₁ expires, the output R switches ON.
When S switches OFF, the off delay t₂ starts.
After t₂ expires, the output R switches OFF.

When S switches ON, R remains OFF.
When S switches OFF, the output R switches ON for t.
After t expires, R switches OFF.

WhenS is triggered again, the time t resets and starts again immediately.
When t expires, the output R switches OFF.

Zeitfunktionen-07

U – Pulse sequence monitoring

The function provides monitoring of pulse separation and triggers an alarm if pulses are too close together. If the separation becomes smaller than the set time tP, an alarm output is activated after an additional delay tV. The monitoring starts with S1 or S2.
If the pulse separation of P is smaller than tP, an alarm output is activated after the alarm delay tV.
If the pulse separation is larger than tP, no alarm is triggered.
The start‑up behaviour depends on the selected input S1 (Monitoring begins immediately with the first pulse. There is no suppression of alarm monitoring during start‑up.) or S2 (Monitoring begins after the short‑out time tA to prevent false alarms during system start-up)

V – Pulse sequence monitoring

The function provides monitoring of pulse separation and triggers an alarm if pulses are too far apart.
The monitoring starts with S1 or S2.
If the pulse separation of P is larger than tP, an alarm output is activated after the alarm delay tV.
If the pulse separation is smaller than tP, no alarm is triggered.
The start‑up behaviour depends on the selected input S1 (without start‑up short‑out tA) or S2 (with start‑up short‑out tA).
