They are extremely reliable, proven through many years manufacture and use, and are compatible with all similar products manufactured world-wide. Our engineers can offer invaluable advice on the choice of relay best suited to your requirements. VP SERIES VPAC SERIES SUMMARY OF TYPES This is a shaded pole version of the VPL (longer coil) series, BASIC VP SERIES suitable for ac operation on 50hz supplies (other frequencies to Contacts 2 4, 6 and 8 pole contact arrangements are available, special order). with a choice of contact materials to suit applications from low to heavy duty. BRITISH TELECOM APPROVED RELAYS These relays conform to British Telecom codes BT23 and BT32. Coils Nominal coil voltages range from 6 to 200V dc, with three For BT23 the contact material is always code G whilst for BT32, types of coil to give the user a liberal choice of operating voltages. code F is used. Solderability of all relay terminals complies with BT specification. AC Operation For ac operation a range is available with built-in rectifiers. See also shaded pole (long coil) VPAC Series. SOCKET AND RETAINING CLIP Relay sockets and retaining clips (ordered separately) are Sensitive Operation Special adjustments can be made which available to suit the different case sizes. Sockets are available with provides increased sensitivity of operation, denoted by SEN in the printed circuit pins or solder tags. ordering code. OMISSION OF EARTH SCREW/PIN Mounting Available as a plug-in relay (also suitable for direct For applications where the earthing facility is not required, the wiring) or for printed circuit mounting with alternative pin layouts. earth screw or pin can be omitted, obviating the need to drill printed circuit boards or panels. VPR SERIES Bistable, polarised relays with either single or double wound coils, EARTH CLIP capable of being pulsed at a minimum of ten milliseconds. Wiring sockets are supplied complete with an earth clip (loose piece) enabling the relay to be earthed via the fixing screw. VPL SERIES Similar to the Basic VP Series but having longer coils offering an extended voltage range. STANDARD CONTACT ARRANGEMENTS AND CASE SIZE FIG. I CONTACT TYPE S TC 5A HD NO.

COIL DATA BASIC VP SERIES FIG 3 Short coils (case 1, 2 or 3, see Fig. 1 & 2). The tables below list the characteristics of all standard Basic VP Series relay coils. Note, against Minimum Volts the sub-headings refer to the various options. i.e. S = low level or light duty single contacts. TC = twin contacts. 5A = 5 amp contacts. HD = heavy duty contacts. SEN = sensitive adjustment. The characters below these sub-headings refer to the number of poles and the contact action, i.e. M = make, B = break, C = changeover.
