Iskra tikalni d ementi Automation components Miniature relays PR 15,16,17 15,16,17 Application PR 15, PR 16 and PR 17 are natural, monostable miniatu re DC relays. Their high operating reliability, perfect elec trical and mechanical characteristics and standard dimen sions enable widely and efficiently use in signalling equip ment, telephony, in digital and measuring equipment, in automation, and many other fields. Two of their best fea tures are the small consumption and an extremely wide voltage and temperature range of operation. Installation The types PR 15, PR 16 and PR 17 miniature relays, fitted with flat contact legs may be positioned directly on either metal or insulation surfaces through earthing screws M2.3, 4.5 mm long, projecting from the base. The normal way of installation is by using a special socket in which the relays are kept reliable by locking springs. Printed wiring types (T) of this relays can be soldered directly to printed circuit'i (PCB). The contact pins are arranged in a 2.5 mm standard pattern as shown in the printed wiring sockets drawings. Design The PR 15, PR 16 and PR 17 miniature relays are elec tromagnetic units using an identical magnet system with different contact sets. The PR 15, PR 16 and PR 17 differ in size but the height and the width of this types are equal. The relays have transparent plastic dust cover providing easy inspection. The contacts can be operated manually by inserting a needle through the aperture in the base and pressing the armature against the magnet core. The relays comply with the IEC, Publication 255-1-00. Versions of relays The size of a relay is established by the type of contact set. As for the technical details, please refer to the tables herein, including the main electrical and mechanical cha racteristics of the individual version of miniature relays as well as the winding details. The individual rated values (such as attraction time, mechanical life, etc.) were measu red at a standard voltage. Versions of relays (P, R, S. T, K) with double contact rivets enable reliable switching operation also at very small con tact load. Sockets and installation parts The relay PR 15, PR 16 and PR 17 may use two types of sockets, a printed wiring type and a soldering type. Printed wiring sockets are directly soldered to the boards with the contact pins arranged in a 2.5 mm standard pattern (see drawing). The relays are kept in position by stainless steel locking springs.
