Features/Benefits
Current limiting output
Thermal protection
Automatic recovery
Overload protection
Dual output: Two relays in one package
Description
The LPD70 is a dual-output 28Vdc plastic relay with internal thermal protection. The relay utilizes optical isolation to provide excellent input-to-output isolation. The LPD70 offers a current limiting output to protect itself and associated load circuits from transient current overloads. During an overcurrent condition, the LPD70 clamps the current to a safe operating value. The LPD70 also offers thermal protection. The thermal protection is activated by junction temperature. In case of an overload or shorted load condition, the thermal protection limits the junction temperature. The LPD70 returns to normal operation automatically once the overload is removed.

SIF 4
The new SIF industrial relays with an element height of just 10.9 mm are worldwide the flattest 4 to 6-pole relays with forcibly guided contacts and can professional switch at 8A.
The monostable, neutral magnet system requires a mere 660mW (6 poles) or 700mW (4 poles) coil drive capacity and can be lowered to approx. 200 mW after switching on. If the fixation pins on the relay's underside are taken advantage of as stand-off, the relay height is approx. 12.1 mm and SMD of up to 1mm element height can be placed under it. The SIF4 and SIF6 are washproof (RTIII) and RoHS-conforming.
The hard-silver alloy, free of heavy metals, is suitable for switching capacities from 5mA to 8A (AC-1). Moreover, notched-crown contacts are used which combine the benefits of crown, twin and knife-edge contacts. This guarantees industrial safe and reliable contact making over very long operation periods at low switching loads (feedback circuits).
With a base area of approx. 53.6 mm x 33.5 mm of the SIF6 and approx. 41.0 mm x 29.4 mm of the SIF4, special care has been taken to maintain the safe separation of all current carrying circuits (test voltage 4,000 Veff.). The high shock and vibration resistance (AK15g / 10g) is also confirmed by the common approbations of the TUeV, UL, SEV etc. |

SIF 6
Relays for areas with a high explosion hazard must satisfy special safety requirements. Voltage flashovers and short-circuits can have devastating consequences. This is why Elesta relays pays highest attention to its products featuring generously dimensioned clearances and creepage distances. With the SIM range of relays, for example, these amount to >14 mm between control and load side, and the test voltage applied during one minute is 5,000V eff. As a result these relays can also be used in applications requiring explosion protection.
Within the contact assembly, clearances and creepage distances of >5.5 mm exist and a test voltage of up to 4,000V eff. is applied, depending on the relay type and contact execution.
Small size: the base of the two-contact version is only 34 mm2, the three and four-contact version 45 mm2.
Impressive electrical 'power': At a nominal switching capacity of AC-1 250V8A the contacts reach a useful life of >100,000 switching operations. Thanks to the gold-plated crown contacts it is also possible to reliably switch small signals of a capacity of a few milliwatts.
SIM relays comply with the European standard DIN EN 50205. Next to all standard coils we also offer special coils on request. |

Description
ZD20CF Series Relays have optical isolation between relay input and output. Loads may be connected to either the positive or negative output terminals. ZD20CF Relays act as electronic professional circuit breakers that sense shorted loads or other overload events and then trip-off. Relay contacts open and no current flows through the relay and associated loads. These relays prevent over-current damage to the system. Cycling the relay on-off removes the tripped or latched-off condition and returns the relay to the normal operating state.

| Electronic control circuits built on PCB’s demand relays that can be populated with the same machinery currently used in the production stations. The Magnecraft SIPS and DIPS are built in small industry standard package styles that do not require unique machinery to populate. The SIPS and DIPS can even withstand a lead-free solder re-flow process so a pin-thru-paste application is possible. |

SIP 6
Applications with a high number of operations and major switching loads are extremely demanding as far as the contact life is concerned. So far, one resorted in such cases to small or auxiliary contactors wired between the actual load. This is not necessary any more: a new development of ELESTA relays GmbH enables the direct activation of e.g. electricity motors at a switching load of 380...440V up to 4.4 kW (6 HP).
The "power package" introduced under the type designation "SIP 512" (2 control contacts, 4 output contacts) is the strongest safety relay so far of this innovative Swiss manufacturer. The solid contacts (AgSnO2) are designed for inrush currents up to 60 A. Equally possible is the continuous carrying of a contact current of 16 A. At a resistance load of AC1 16 A/250 V the contact life is at least 250,000 switching operations.
As with all products of ELESTA relays, the safety of persons and material assets is in the forefront also with the "SIP 512". In compliance with standard EN 50205 all 6 contacts are fully forcibly guided against each other. Thanks to the big distances between the individual contact chambers (> 8mm) this relay permits to safely switch three-phase mains up to a switching voltage of 480 V (AC). |

Reed switching technology is used in all market segments including: test and metering equipment, medical electronics, Telecom, automotive, security, appliances, general purpose, etc. Its growth rate is stronger than ever, where the world output cannot stay abreast with demand.
As a technology, the Reed Switch is unique. Being hermetically sealed, it can exist or be used in almost any environment. Very simple in its structure, it crosses many technologies in its manufacture. Critical to its quality and reliability is its glass to metal hermetic seal, where the glass and metal used must have exact linear thermal coefficients of expansion. Otherwise, cracking and poor professional seals will result. Whether sputtered or plated, the process of applying the contact material, usually Rhodium or Ruthenium, must be carried out precisely in ultra clean environments similar to semiconductor technology. Like semiconductors, any foreign particles present in the manufacture will give rise to losses, quality and reliability problems.
Over the years, the Reed Switch has shrunk in size from approximately 50 mm (2 inches) to 6 mm (0.24 inches). These smaller sizes have opened up many more applications particularly in RF and fast time domain requirements. |
