6 6 application notes General High Voltage Reed Relays Contact Arrangement Relays manufactured by Crydom have one of the following contact arrangements: Form A : Form B : Latching : Normally open - energise to close contacts Normally closed - energise to open contacts Contact is bistable - energise ÒsetÓ coil to close contacts; energise ÒresetÓ coil to open contacts Coil Suppression It is recommended that all relay coils be suppressed by a diode. This is essential for latching relays. Operate and release times for the relays are quoted with coil suppression fitted. Soldering & Cleaning CrydomÕs reed relays are high performance products and the materials and methods of construction are significant factors in achieving performance specifications. The following guidelines should therefore be followed when adopting assembly, soldering and cleaning processes: 1) Soldering. Crydom propose that either low residue fluxes are used in the soldering process (to eliminate the need for cleaning), or that the reed relays are fitted onto the PCB after the cleaning process has taken place. If a solder bath is employed the maximum immersion time recommended is 10 seconds at 250 C or 3 seconds at 350 C. FRD12000/13000 Series: Electrical connection to the contacts of the FRD12000/13000 Series relay is via the reedswitch leadout. Care must be taken when hand soldering, as physical and thermal shocks can damage the glass to metal seals. A thermal shunt (aluminium clamp) carefully applied to the reedswitch leadout, adjacent to the glass seal will reduce the chances of breakage due to thermal shocks. Alternatively, the relays should be warmed prior to soldering. 2) Cleaning. It is impossible for Crydom to offer blanket approval of methods, due to the many and varied automatic cleaning systems now available to conform to recent legislation. The principal function of a high voltage reed relay is to isolate as high a voltage as possible. In order to achieve this all Crydom high voltage reed relays employ evacuated reed switches. These switches are available with either Tungsten or Rhodium contacts depending upon the switching characteristics required. As with all reed relays they are susceptible to mutual magnetic interference when mounted in close proximity to each other. These parameters are discussed in greater detail below. Isolation Voltage The isolation voltages specified correspond to DC or AC peak. At mains frequencies (e.g. 50 or 60Hz) the two may be considered directly equivalent. Contact Material - Rhodium vs Tungsten Rhodium contacts should be used where very low contact resistance is required or when power switching at <1000V is undertaken. Tungsten contacts perform best when switching high voltages (1-10kV) at very low current. It should be noted that switching power will reduce relay operating life - the factory should be contacted for advice on specific applications. Magnetic Screening Crydom high voltage reed relays are generally supplied with magnetic screening fitted. However, this is not absolute and so, if the minimising of interference is critical, the mounting configuration in figure 1 below is recommended. If, after the soldering process, the customer wishes to clean PCBÕs containing Crydom reed relays then the use of post operative cleaners such as IPA or HCFC based solvents with low pressure brush applicators is recommended. Any customer wishing to use Figure 1 : Recommended Mounting for S and D Series High Voltage Reed Relays an alternative cleaning system should ensure that the fluids and processes are appropriate for application on Crydom reed relays. CrydomÕs devices are not hermetically sealed and as such, exposure to certain fluids can result in the degradation of the relay materials and subsequently a reduction in the electrical performance. Please contact Crydom for further information on the suitability of various cleaning solutions.

7 RF Reed Relays The basic requirements of RF reed relays are to provide minimal RF signal loss and very low contact resistance over a long operating lifetime. This is achieved in Crydom RF reed relays through the use of copper plated reed switches with Rhodium contacts in conjunction with carefully designed coil assemblies. They are intended for use across the frequency range 1-30MHz and typical RF parameters for an RF reed relay across this band (measured in a 50 Ohm system) are shown in figure 2 below: As an illustration of the effect of relay screening on ESR, measurements taken under load at 30MHz (i.e. the worst case frequency) are shown in figure 3 below for fully, partially and unscreened ÒFRDÓ series reed relays. 7 Figure 2 : Typical Parameters of Crydom RF Reed Relays Particular to RF reed relays are the effects of RF and magnetic screening and these are discussed in more detail below. Also, high voltage isolation considerations are specific to RF conditions. RF Screening When an RF current is passed through the switch of a reed relay an electromagnetic coupling between reed switch and coil results in some energy being dissipated in the coil. This dissipation manifests itself as an addition to the effective series resistance (ESR) of the relay and, at currents of several amps, heating of the relay coil. RF coil heating is greatest at high frequencies and varies in proportion to the square of the RF current carried in the switch. It is this factor which limits maximum carry current at high frequencies and ambient temperatures. The purpose of RF screening is to reduce these losses and extend relay performance at high frequencies and high ambient temperatures. Crydom RF reed relays are available with no screening, partial screening and full RF screening of the coil, depending upon the requirements of the application. Relays without an RF screen have restricted current carrying capability at high ambient temperatures and frequencies (and a higher associated ESR). However, this suits many typical ATU applications well, as the highest currents occur only at the lower frequency bands (e.g. 2MHz). Relays with partial RF screening have extended current carrying performance at elevated ambient temperatures over unscreened variants. Relays with full RF screening represent the ultimate in low loss RF reed relay design. The ESR and resulting coil heating are significantly lower than for other types and this makes them suitable for applications in high ÒQÓ circuits where high currents are present over the whole frequency range. Figure 3: Effects of screening on ESR Magnetic Screening When power is supplied to the coil of a reed relay a magnetic field is produced. When relays are mounted in close proximity this can result in mutual magnetic interference. However, Crydom RF reed relays are generally not fitted with magnetic screens, as the presence of ferromagnetic material around the coil can adversely affect ESR and RF coil heating as described above. For applications where relays are mounted in close proximity the recommended mounting configuration is shown in figure 4 below. Figure 4 : Mounting Configurations to Minimise Magnetic Interference ( *Note Orientation) Isolation Voltage All withstand voltages are specified and tested at DC. However, high voltage breakdown mechanisms at high frequency differ to those at DC. In general, breakdown across the reed contacts occurs at a higher RF peak voltage than DC. Conversely, breakdown outside the switch (e.g. switch to coil or screen), caused by surface tracking, can occur more readily at high frequency than at DC. Verification of any particular voltage and frequency combination can be undertaken by Crydom upon request.
