The RT7 is a universal relay that can be used to supervise both safety devices and the Internal safety of your machinery. In addition, you can select the safety level that is required for each installation. all this is possible because the RT7 has the most versatile input options arrangement available on the market. The RT7 can therefore replace many other relays.

- The RT7 has 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
- A Soft™ stop allows machinery to brake and stop gently before power is removed
- RT7 is manual or automatic resetting
- A manual supervised reset is used for gates and other safety devices that can be passed through, while an automatic reset is used for small safety hatches if deemed appropriate from A risk point of view
- 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 needs to be reset
- Single or dual channel input
- Test input for supervision of external contactors
- LED indication of supply, inputs outputs short circuit and low voltage level
- 0, 1.0, 2.0, 3.0 s delay times
- Three voltage free transistor information outputs
- Quick release connector blocks
- AgSnO2+ Au flash contact material
- 5A gL/gG fuses output 1/2 (external), 3A gL/gG fuses output 3/4 (external)
- 6 A gG conditional short circuit current
- 2.5 kV impulse withstand voltage
- 300 ohm (S14,S24,S34), 150 ohm (S44, X1) maximum input wire resistance at nominal voltage
- Meets safety category 4
