Reed Relays & Optocouplers | Introduction

Reed relays contain an electromagnetic coil and reed switch. When power is applied to the coil, the reed switch is activated. Because the contacts in a reed relay are hermetically sealed, the contacts can switch low level signals as low as femtoamps and nanovolts. Reed relays are ideally used for switching applications requiring low and stable contact resistance, low capacitance, high insulation resistance, long life and small size.  Our optocoupler series can safely handle input/output isolations as high as 20kVDC and insulation resistances as high as 1013 ohms. Many of the optocouplers series also meet intrinsic safety requirements of ATEX, making them suitable to operate in all kinds of extremely hazardous environments. They also transfer their digital or analog signal information from input to output drawing no potentially hazardous arc. Optocouplers have no moving parts and operate safely for billions of operations, are not affected by magnetic fields, and can operate or transfer information at a 50 kHz rate.

Intrinsically Safe

Our intrinsically safe or ATEX approved reed relays & optocouplers are tested such that they will not become an ignition point when subjected to short circuits or adjacent component failures. They must also switch to a defined state when subjected to overload conditions. Our optocoupler series are all ideal for these types of environments, such as in the mining industry, chemical processing plants, refineries, power stations and high dust producing plants. Any potentially flammable atmospheres represent areas of applications for these products. Standards for these components are presented in EN500200. The required air and creepage paths as well as the electric strength are defined in detail as follows: For voltage specification, a peak voltage of 375 Volts must not be exceeded 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

Optocouplers

Optocouplers are composed of two circuits: an input circuit and an output circuit. A light emitting diode (LED) is the key input component, where the key output component is a photo-detector. Passing a current of approximately 10 ma through the two input terminals and through the light emitting diode, with the correct polarity, converts the electrical current into photons. The photons are then directed down a light tube or tunnel. At the end of the tunnel, the photons are incident on the photo detector that converts the photons back to an electric current. In this manner, the input information is transferred and amplified in the output detection circuit without any direct electrical conducting path. The longer the light tube the greater the distance between the metalized input terminals to the metalized output terminals. This insures a greater insulation resistance and high voltage isolation. Optocouplers handle hazardous environments and meet ATEX intrinsic safety requirements. Our line of optocouplers can safely handle input/output isolation as high as 20,000 VDC that have met and been certified for the stringent requirements of ATEX (Directive 94/9/EC and 1999/92/EC). This directive applies to equipment and protective systems that are used in factories where potentially explosive atmospheres exist such as in mining operations, flammable gas processing plants, some medical processing plants where ESD could be a real problem, and in any factory that requires high isolation and non-arcing environments.

Relay Modules

Relay modules have various input/output configurations and are designed in either a low-profile surface mount (SMD) package, dual in-line through-hole, or plug-in design. They feature multiple switching configurations ranging from 4-pole up to 8-pole (2C Matrix). Some relay module come equipped with the latest integrated drivers, eliminating the need for external activation electronics.

RM05-8A Reed Relay

8-pole low profile through hole mount (THT) high frequency (RF) RM05-8A Series Reed Relay module with one serial digital 8 bit input channel, to drive a double output matrix with 4 to 1 channels each. Equipped with an 8 bit shift register 74 HC(T)595 and new drivers. Designed to significantly reduce PCB space, saves on wiring costs, and assembly costs.

Ultraminiature 8-pole low profile through hole mount (THT) RM05-8A-SP Series Reed Relay module with standard dual in-line (DIL) pin-out (2mm raster) and integrated magnetic shield for high density board mounting. Equipped with an 8-channel relay driver with MAX4823 with kickback protection and parallel activation electronics. Designed to significantly reduce PCB space at 24% smaller than our RM05-8A, saves on wiring costs, and assembly costs.

RM05-4A Reed Relay

The 4-pole RM05-4A series is an (RF) high frequency reed relay packaged as a low profile, (SMD) surface mount reed relay module. This RF reed relay is capable of switching beyond 5.5 GHz with <40ps rise times for switching fast pulses.

Special Feature Reed Relays

Our special feature reed relays offer unique characteristics such as low power consumption, latching, high insulation, and much more.
