Product Information

The ABB Safety Relay/Expansion Relay (BT51T) is designed to connect safety devices, such as emergency stops, directly in the voltage supply circuit to the relay. Despite a maximum built-in width of 22.5mm the relay is very powerful. With 4 NO safety outputs, test input and complete internal supervising, the BT51 is quite unique.
