Eight Selectable Timing Functions
The Finder 83.02.0.240.0003 provides eight timing functions for different industrial switching and process-control requirements:
- AI – On-delay: Activates the timed output after the selected delay following application of the supply voltage.
- DI – Interval: Activates the output when the supply is applied and releases it after the selected interval.
- GI – Delayed pulse: Produces a timed pulse following an initial delay.
- SW – Symmetrical flasher: Alternates the output between ON and OFF states, beginning with the ON interval.
- BE – Off-delay with control signal: Delays output release after removal of the external control signal.
- CE – On- and off-delay with control signal: Provides delayed output operation when the external control signal is applied and removed.
- DE – Interval with control signal: Starts a timed output interval using the external control input.
- WD – Watchdog: Provides a retriggerable timing interval initiated through the external control input.
The operating function and output configuration should be selected before energising the timer, following Finder's installation instructions.
Multifunction Timing for Hazardous-Location Control Systems
Electrical control systems installed in potentially explosive atmospheres require equipment selected for the applicable hazardous-area classification, environmental conditions and installation method. The Finder 83.02.0.240.0003 is a specialised timer relay designed for use in specified IECEx, ATEX and North American HazLoc applications.
Its ATEX II 3 G Ex ec nC IIC T4 Gc and IECEx Ex ec nC IIC T4 Gc markings identify suitability for specified Zone 2 gas-atmosphere installations. Its North American hazardous-location classification additionally supports appropriately designed Class I, Division 2 applications.
The relay combines these hazardous-location characteristics with a versatile 24–240 V AC/DC supply, allowing it to be used across a range of industrial control voltage systems. Its two changeover outputs can be configured as two timed contacts or one timed and one instantaneous contact.
The eight timing functions support delayed starting, timed intervals, flashing, pulse generation and watchdog control. Front-mounted adjustment controls simplify configuration, while the optional external potentiometer provides an additional timing adjustment method where permitted by the installation design.
Important: Hazardous-location approval does not mean the timer is suitable for every explosive atmosphere. Installation must comply with the specific certificate conditions, equipment markings, permitted ambient temperatures, wiring requirements and applicable hazardous-area regulations. The device must not be assumed suitable for Zone 0 or Zone 1 applications.
Typical Applications
- Zone 2 industrial automation control panels.
- Class I, Division 2 hazardous-location electrical installations.
- Chemical processing plant auxiliary control systems.
- Oil and gas equipment control interfaces in appropriately classified areas.
