Relays & Optocouplers |Introduction

Reed relaysuse the reed switch as the heart of their switching mechanism. And as a result canswitch billions of reliable operations(load dependent). Also they canswitch up to 10,000 Volts and hold off up to 15,000 Volts.Furthermore, reed relaysswitch very low level signalsas low as femtoamps and nanovolts. This is due to their environmentally orhermetically sealed contacts.Additionally they are very small and offer manyunique switching abilities unlike semiconductor and electromechanical relays.These include stable low contact resistance<150 milli-ohms, low capacitance,high insulation resistance >10^14 Ohms, andcarry currents up to 5 Amps continuous and 10 Amps pulsed.Reed relaysoperate in the 500 microsecond to 3 millisecondrange andwithstand shock up to 150G.We offer engineered relay solutions for a broad spectrum of product applications in all major markets.

High frequency reed relaysare capable of switching signals from DC up to 7 GHz. This is achieved by keeping the signal path as short as possible. Additionally the relays use an internal coaxial shield with a consistent 50 Ohm impedance path. Not only is it excellent with RF signals, but is also great for digital signals where the skew rates or effects on the rise time of fast digital pulses is less than 40 picoseconds through the relay. Internal magnetic shield prevents any magnetic coupling effects between relays when designing a two dimensional or three dimensional relay matrix. TheseRF reed relayshave a flat frequency response out to 20 GHz. Their cost is moderate and stable. Their size is becoming smaller and smaller.

Intrinsically Safe

Ourintrinsically safeorATEX approved reed relays & optocouplersare tested such that they will not become an ignition point. Not even in the presence of short circuits or adjacent component failures. And ATEX reed relays must also switch to a defined state when subjected to overload conditions. Ouroptocoupler seriesare designed for these types of hazardous environments. Examples ofhazardous locationsincludemining, chemical processing plants, refineries, power stations and high dust producing plants. As well as any potentially flammable atmospheres. Standards for intrinsically safe components are presented in EN500200. The required air and creepage paths as well as the electric strength are defined in detail as follows: The peak voltage cannot exceed 375 Volts in order to meet accepted worldwide standards. The sum of the input and output voltages must not be higher than 375 Volts Peak. The coil input has a voltage of 24 Volts max. and the contacts produce 230 VRMS or 325 volts peak output. Input plus output = 24 + 325 = 349 Volts peak. Here the safety margin for the voltage for the input and output meet their peak voltage limit of 375 volts. The air path for isolation of this voltage is 6mm and the creepage path is 10mm. The isolation inside the component through potting compounds is 2mm. Another important value is the Comparative Tracking index (CTI) value of plastic. In this case, the value must be greater than 175. The electric strength between the input and output is tested at 1500 VRMS or 2x the nominal voltage +1000.
