Safety module/system Vital
ABB
Safety module/system Vital
Art. nr.: 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.

Voltage measuring relay 3-phase DPB/PPB
Carlo Gavazzi
Voltage measuring relay 3-phase DPB/PPB
Art. nr.: 3864715
Monitors phase symmetry, phase break and phase sequence
3-phase AC+N TRMS monitoring relays for phase symmetry, phase failure and phase sequence. mounting on DIN rail or 11-pin socket.
Technical data
Function description:The relay drops when the phase symmetry exceeds the set value (5-25%), after a set time delay (0.1-30s). The relay also monitors phase failure and phase sequence, in case of incorrect phase sequence or phase failure, the relay trips without a time delay. All relevant data and connection diagram are clearly marked on the side of the relay.
3 LEDs. Green lights up when the control voltage is connected. Yellow lights up when the relay is switched on and red flashes during the countdown, and lights up with a steady light in the event of an alarm.

Power control relay Type EIL/EIH
Crouzet
Power control relay Type EIL/EIH
Art. nr.: 3862330
Description
Monitoring of DC or AC. Monitors overcurrent or undercurrent Only 22.5 mm wide
Functional description
When the value of measured current reaches the set limit value, the relay changes after time T1 (0.1 to 3S). After alarm, the relay switch returns when the current reaches the hysteresis limit, i.e. the limit value plus or minus the set hysteresis. Memory, above or below the current function, is selected with two switches, memory is reset by de-energising the relay. While booting time starts T2 (1 to 20 S) before the contact switches and relay starts to measure, in order to prevent false alarms, for instance, with high starting currents. Green diode indicates the supply voltage Red diode indicates active relay output. Measurement current area 2 to 500 mA EIL/0.1 to 10A EIH.
Safety sensor Eden OSSD Adam
ABB
Safety sensor Eden OSSD Adam
Art. nr.: 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.

Voltage measurement relay 3-phase for over and under voltage
Carlo Gavazzi
Voltage measurement relay 3-phase for over and under voltage
Art. nr.: 3864692
3-phase monitoring relays for phase sequence/Phase break and Over-/Under Voltage for mounting on DIN rails or 11-pin base.
Functional description
The relay is pulled when the phases or the phases + 0 are within the set limits, the relay falls if the limit values are passed after the set time delay (0.1-30s). The relay also monitors phase breaks and phase sequence, at the wrong phase sequence or phase break the relay falls without time delay.
All relevant data, as well as the circuit diagram are clearly marked on the side of the relays.3 LEDs. Green lights up when the control voltage is connected. Yellow lights up when the relay is on and Red flashes during the time, and is lit with a steady light in alarm.
