Safety module/system Vital

Safety module/system Vital

Art. no.: 3858760

Application areas: Emergency stop, light curtain, non-touch sensor (EDEN), gate switches, light beam, hatch breaker, contact mat, contact list, all in the same security circuit.
Security module, Vital, only 22.5 mm wide, is the heart of a concept that means that in one and the same safety circuit one can easily install one or several different security components and still achieve safety category 4 according to EN 954-1. Vital is based on a dynamic single channel concept, unlike conventional 2-channel safety relays. Up to 30 dynamic transducers can be installed directly into the safety circuit that is monitored by just one Vital module. Mechanical sensors with connectors can also be linked in and get dynamic function with the help of adaptation unit Tina. Vital has automatic or manual monitored reset, two safety outputs and information output that is both used for recovery indication and for information to the PLC. Test input for monitoring of, for example, contactors, relays and motors can easily be connected up. The relay has removable terminal blocks.

Safety sensor Eden OSSD Adam

Safety sensor Eden OSSD Adam

Art. no.: 3830215

The Eden OSSD is a coded non-contact safety sensor that is used together with a safety relay or a safety PLC. The Eden OSSD consists of two units, Adam and Eve. Maximum safety with fewer units.
Eden OSSD makes it easy to achieve PLe:
- with only one Eden OSSD per protective device, without the need for regular tests (ISO/TR 24119)
- with the option to connect up to 30 Eden OSSDs in series.
The Eden OSSD makes it possible to save on cables and safety relays as you can connect a reset button with indicator light directly to the Adam OSSD-Reset, which in turn monitors the reset function and manages the indicator light. The Eden OSSD's flexible mounting options and its compact size make it easy to place. Its M12 connector simplifies installation and future replacement of the device. The Eden OSSD has comprehensive function indication with LED and information output that facilitates troubleshooting, which leads to reduced downtime. Its large sensing distance provides a better tolerance for vibrations and thus minimizes the risk of accidental stops. Eden OSSD has a high enclosure class in the standard version, IP69K, as well as a wide temperature range, -40 to +70 degrees. This makes it possible to use the Eden OSSD in extreme environments.

Loose key, fixed (GD2)

Loose key, fixed (GD2)

Art. no.: 3802520

Electrically lockable key switch with a locking force of 2,000 N. The switch has a status indication that shows whether the switch is locked or unlocked. It also has a rotatable head which gives four different key inputs. In the event of a power failure, the breaker can be forcibly opened using an override key. The control signal for unlocking the breaker should come from a standstill monitor (see section "Safety modules") which then unlocks the breaker and releases the key when the machine is in a safe position.

Monitoring of phase sequence and phase failure control relay 3-phase

Monitoring of phase sequence and phase failure control relay 3-phase

Art. no.: 3864690

Functional description
The relay monitors that all three phases are live, and that the phase sequence is correct. The relay is on as long as these conditions are met. When monitoring engines, the relay falls when one of the phase-phase voltages is less than 85% of the other phase-phase voltages.
All relevant data, as well as the circuit diagram are clearly marked on the side of the relays

Light curtain Orion 3

Light curtain Orion 3

Art. no.: 3830950

Orion3 is used when you need to detect humans, usually to prevent access to the risk area. One device is active and contains both transmitters and receivers. The other is a mirror unit and only reflects the signal and therefore does not need to be energized. Orion3 Extended has, among other things, a built-in function for muting. It is used, for example, when bypassing the input and output of materials on the transport path etc. NOTE! The units are delivered separately, light beam and mirror unit.

Light curtain Orion 2

Light curtain Orion 2

Art. no.: 3830940
