ABB Single/Dual-Channel Light Beam/Curtain, Safety Mat/Edge, Safety Switch/Interlock Safety Relay, 24V dc, 5 Safety

The RT7 series from ABB 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.
