**RT7 Safety Relay Series**

The RT7 series from is a universal relay to monitor both external and internal safety aspects of your machinery. The RT7 safety relay has a very versatile input configuration, therefore many safety relays can be replaced by the RT7. ABB have equipped the RT7 with four 4 NO dual safety outputs of which two may be delayed for up to three seconds in order to achieve a safe and ‘soft’ stop. Another option which the RT7 provides from ABB is manual or automatic resetting. A manual supervised reset is used for gates and other safety devices that can be bypassed, while an automatic reset is used for small safety hatches if deemed appropriate from a risk point of view. In addition, the RT7 has information outputs that follow the inputs and outputs of the relay. These outputs indicate if, for example, a gate is opened or closed, if there is a delay or if the relay requires to be reset.
