SCR-4-TD延时安全监控继电器 IDEM全系列继电器

Safety Monitoring Relays with Time Delay. Various output configurations (see below)

IDEM’s SCR-4-TD range are all pur机e safety monitoring relays that combine time delayed and non time delayed contacts in a compact 22.5mm housing.

This permits dangerous components of a system to be switched off quickly and safely, whilst at the same time other circuits are still supplied with voltage for up to 30 seconds (adjusted on the SCR-4-TD by a potentiometer).

If the application requires time delayed opening of a safety circuit following activation of the stop signal then the SCR-4-TD range will provide combination of instant and variable delayed contacts.

This may be useful for applications that rely on PLC control to provide an initial controlled shutdown but ultimately requires a delayed opening of safety circuit.

Variants available:

SCR-4-TD-1 with Instant 3NC and Delayed 1NC

SCR-4-TD-2 with Instant 2NC and Delayed 2NC

SCR-4-TD:具有延时的安全监控继电器

具有延时的安全监控继电器。

各种输出配置(见下面)

IDEM的SCR-4-TD系列是全用途安全监控继电器，在紧凑的22.5mm外壳中结合了时间延迟和非时间延迟触点。

这允许一个系统的危险部件被快速和安全地切断，同时其他电路仍然提供高达30秒的电压(通过电位器调整SCR-4-TD)。

如果应用程序需要在停止信号激活后延时断开安全电路，则SCR-4-TD范围将提供即时和可变延时触点的组合。

这可能对依赖PLC控制的应用程序提供一个初始控制关机，但好终需要安全电路的延迟打开有用。
