Finder has announced the introduction of a range of eight modular, 22.5mm wide rail-mounted timers designed to provide a complete range of timing functions, while keeping part number holdings to the absolute minimum.  The multi-voltage 83 Series of multi-function and mono-function timers handles 14 different timing functions, with time scales between 0.05 seconds to 10 days and offers either single or double pole variants.

To maximise flexibility the timers support a very wide working voltage range, from 24V through to 240V AC or DC, making them suitable for mains or low voltage AC operation as well as DC battery supplies.  With changeover contacts rated for 16A, the 83 Series is capable of switching AC1 loads of up to 4KVA or single phase motors up to 0.5kW.  For easy maintenance, both flat blade and cross head screw drivers can be used to adjust the range and function selectors, the timing trimmer and to disengage the rail mounting clip.

The single pole 83.01 and double pole 83.02 multi-function timer variants both offer up to 8 different timing functions, including a special watchdog function allowing users to monitor repeating processes by resetting the time period each time a “watchdog” pulse is received, with the continuous presence or absence of a pulse beyond the set time triggering the release of the output contacts.

The 83.02 timer also provides the facility of external potentiometer time setting, enabling the timer to be adjusted from the front of control panel or enclosure, whilst assuring the security of timer function and time scale settings.  In addition, to further maximise flexibility and minimise part number stocking, it also offers users the option to select between either 2 timed or 1 timed and 1 instantaneous contact.

The third multi-function timer in the series, the 83.91 provides 4 asymmetrical flasher timing functions: starting pulse on; starting pulse off; as well as starting pulse on and starting pulse off both with a control signal input allowing timing to be initiated from a remote sensor operating at a voltage other than the supply voltage.

Completing the 83 Series timer range are 3 single pole mono-function timers:  the 83.11 for on-delay; the 83.21 for interval; 83.41 for off-delay with control signal; and a pair of 2 pole mono-function timers: the 83.62 for power-off delay (true off-delay) and the 83.82 for star-delta timing function.

Finder has extended its relay range with versions designed to suit photovoltaic (PV) inverters, domestic appliances and other equipment needing reinforced insulation, high ambient temperature handling and full disconnection contacts.  The latest product introductions comprise the 45.31 16A rated mini PCB relay and 3 special variants of the 66 Series 30A rated power relays.

With an extended 3mm contact gap, the single pole NO 45.31 relay meets the requirements of the EN60730-1 standard for household use and is rated for operation at an ambient temperature up to 105ºC.  It has a high sensitivity 24V DC coil rated at 360mW.  In common with the 66 Series specials, the 45.31 has been designed with an 8mm clearance and creepage distance, ensuring safe separation of supply and output, and reinforced insulation between coil and contacts, meeting the requirements of EN60335-1 (VDE0700).

The 2 pole NO (DPST-NO) 66.22-x600, 66.22-x600S and 66.82-x600 30 amp power relays ensure a contact gap separation of 1.5mm, fully meeting the requirements of the VDE0126-1-1 standard for PV inverter applications.  In addition, the 600S variant provides a 5mm airgap between relay base and PCB for extra cooling particularly in systems where forced air cooling is employed as with many PV inverters.

For added flexibility, the 66 Series relays provide the options of PCB and flange mounting and Faston 250 terminations.  A 35mm rail mounting adaptor is also available.  A wide range of coil voltages is offered, spanning from 6V through to 125VDC.
