PNOZ s2 safety relay

The safety relay provides a safety-related interruption of a safety circuit.

The safety relay meets the requirements of EN 60947-5-1, EN 60204-1 and VDE 0113-1

and may be used in applications with

} E-STOP pushbuttons

} Safety gates

For your safety

} Only install and commission the unit if you have read and understood these operating

instructions and are familiar with the applicable regulations for health and safety at work

– 3 safety contacts (N/O), instantaneous

– 1 auxiliary contact (N/C), instantaneous

} Safe separation of safety contacts from all other circuits

} 1 semiconductor output

} Connection options for:

– E-STOP pushbutton

– Safety gate limit switch

– Start button

} A connector can be used to connect 1 PNOZsigma contact expansion module

} Operating modes can be set via rotary switch

– Errors

} Plug-in connection terminals (either spring-loaded terminal or screw terminal)

Safety features

The relay meets the following safety requirements:

} The circuit is redundant with built-in self-monitoring.

} The safety function remains effective in the case of a component failure.

} The correct opening and closing of the safety function relays is tested automatically in

each on-off cycle.

} The unit has an electronic fuse.

Block diagram/terminal configuration

Automatic start: Unit is active once the input circuit has been closed.

} Manual start: Unit is active once the input circuit is closed and then the start circuit is

closed.

}

Monitored start with falling edge: Unit is active once

– the input circuit is closed and then the start circuit is closed and opened again.

– the start circuit is closed and then opened again once the input circuit is closed.

}

Monitored start with rising edge: Unit is active once the input circuit is closed and

once the start circuit is closed after the waiting period has elapsed (see technical de-
