Safety
Monitoring Relays with Time Delay. Various output configurations (see below)
IDEM’s
SCR-4-TD range are all purpose 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.

SCR-4-TD:具有延時(shí)的安全監(jiān)控繼電器
具有延時(shí)的安全監(jiān)控繼電器。
各種輸出配置(見下面)
IDEM的SCR-4-TD系列是全用途安全監(jiān)控繼電器，在緊湊的22.5mm外殼中結(jié)合了時(shí)間延遲和非時(shí)間延遲觸點(diǎn)。
這允許一個(gè)系統(tǒng)的危險(xiǎn)部件被快速和安全地切斷，同時(shí)其他電路仍然提供高達(dá)30秒的電壓(通過電位器調(diào)整SCR-4-TD)。
如果應(yīng)用程序需要在停止信號(hào)激活后延時(shí)斷開安全電路，則SCR-4-TD范圍將提供即時(shí)和可變延時(shí)觸點(diǎn)的組合。
這可能對(duì)依賴PLC控制的應(yīng)用程序提供一個(gè)初始控制關(guān)機(jī)，但終需要安全電路的延遲打開有用。
變體:
SCR-4-TD-1具有即時(shí)3NC和延遲1NC
SCR-4-TD-2具有即時(shí)2NC和延遲2NC
SCR-4-TD-3具有即時(shí)1NC和延遲3NC
