Page 4: Introduction
SE-434 39 Kungsbacka Sweden Scope The purpose of these instructions is to describe how to use the safety relay BT50(T) in control circuits that are related to functional safety. Prerequisites It is assumed that the reader of this document has knowledge of the following: ·... -
Page 5: Overview
This manual contains information on using the safety relay in control circuits that are related to functional safety. The BT50(T) is designed to connect safety devices, such as emergency stops, directly in the voltage supply circuit to the relay. This relay can be used to expand the safety outputs of Pluto. -
Page 6: Function Description
The NC output 41 – 42 should only be used for monitoring purposes e. g. indication lamp for emergency stop pressed. The BT50T is the same as BT50 except that it also has delay time selectable outputs and additional information output relay. This is explained in the following connection diagrams. -

Safety Function and Safe State Safety Function When the input of the BT50 is de-energized, the output is de-energized. When the input of the BT50T is de- energized, the output is de-energized according to the time settings. Safe state The safe state is when all three NO safety outputs are de-energized. -
