They are extremely reliable, proven through many years manufacture and use and are compatible with all similar products manufactured world-wide.. SUMMARY OF TYPES.. ASI VP SERIES ontacts:,, & pole contact arrangements are available, with a choice of contact materials to suit applications from low to heavy duty. oils: Nominal coil voltages range from to 00V D and to 0V A to give the user a liberal choice of operating voltages. A Operation: For A operation a range is available with built in rectifiers. Sensitive operation: Special adjustments can be made which provide increased sensitivity of operation, denoted by SEN in the ordering code. Mounting: Available as a plug-in relay (also suitable for direct wiring) or for printed circuit board mounting with alternative pin layouts. Socket and Retaining lip: Relay sockets and retaining clips (ordered separately) are available to suit the different case sizes. Sockets are available with printed circuit pins or solder tags. Omission of Earth Screw/Pin: For Applications where an earth facility is not required, the earth screw or pin can be omitted, obviating the need to drill printed circuit boards or panels. Earth lip: Wiring sockets are supplied complete with an earth clip (loose piece) enabling the relay to be earthed via the fixing screw... VPR Series istable, polarised relays with either single or double wound coils, capable of being pulsed at a minimum of 0 milliseconds... Telecom approved relays These relays conform to ritish Telecom codes T and T. For T the contact material is always code 'G' while for T code 'F' is used. VP Relay-&S ontrols Ltd. // Page of

The tables below list the characteristics of all standard asic VP Series relay coils. Note, against 'Minimum Volts' the subheadings refer to various options, i.e. S = Low level or light duty single contacts, T = twin contacts, A = Amp contacts, HD = heavy duty contacts, SEN = sensitive adjustment.

VPR SERIES ISTALE POLARISED RELAYS Short coils (ase, or see tables & ) These are bistable polarised relays having magnetic latching by means of a ceramic magnet. The relay can be pulsed at 0 milliseconds (minimum) sine or square wave. The physical dimensions and base terminals are identical to the asic VP Series, and they are available in single or double wound coils.

ONTAT MATERIALS ode A Fine silver (gold flashed) the most effective material for general purposes and has the highest conductivity of all metals. The bare metal is prone to tarnishing in sulphurous atmospheres, but in all but the very lightest of settings, the wiping action of all the contacts rapidly breaks down the film. ode F % Gold % Nickel arc and weld resistant, hard wearing and the best material for low level applications. (T type ontact Material) ode G 0% Palladium, 0% Silver - It is arc resistant and the least costly of the tarnish-free alloys at normal temperatures. (T type ontact Material) ode I Silver admium Oxide - a hard sintered alloy ideally suited for heavy duty applications with inductive loads. It is less prone to material transfer than Silver on D circuits, but it is not suitable for low voltage low current applications.. ONTAT RATINGS Table. Table ontact Type ode Max. Amps Max. Volts Max.

ONTAT TYPES Single light duty & Amp Twin (T) light duty Heavy duty (HD) Suitable for most general purpose applications. Recommended for all critical applications that require reliable high integrity switching. The relays are constructed using two sets of standard contacts (of the selected type and rating) fixed to bifurcated contact springs. Made from fine silver (code A), the contacts are physically larger than the standard light duty contact to allow for increased dissipation. Double spacers are inserted between springs so that the spring set is larger than that on the normal duty Amp (A) contacts. onsequently the case size and terminal numbering is different from the A types.
