รายละเอียดสินค้า

Sentry BSR and TSR models can be used as expansion relays,

Expansion relays are used to increase the number of safe outputs of another safety relay or a safety PLC like Pluto. This is suitable in applications where several machines need to be stopped.

Sentry BSR models are cost effective expansion relays that can also be used with the -24 VDC safety outputs of Pluto. They offer no timer function.

Sentry TSR10 offers advanced timer functions, such as off-delay, on-delay, time bypass and time reset. The time is set via the display, from 0 to 999 seconds with an accuracy of ± 1%.

Sentry TSR20 offers an off-delay function, 0.5 or 1.5 s selectable by switch. TRS20 is the +24 VDC models and TSR20M the mains voltage model (85-265 VAC/120-275 VDC).
