How to select a solid state relay
When selecting which solid state relay to use it is first necessary to define what it needs to be able to switch and how this needs to be achieved. There are a few useful steps to take and questions to ask:
AC or DC: There are different types of solid state relay used for switching AC or DC. Determining whether AC or DC power is to be switched is one of the most fundamental selections. As AC solid state switches typically use triacs and thyristors they do not work on DC and would not turn the load off, unless the DC falls to zero for some other reason. DC solid state switches typically use MOSFETs as they have a very low ON resistance.
Also remember that the input and output may be different - an SSR may be designed to control an AC output, but require a DC control voltage input, etc. In some instances a bridge rectifier, and possibly other electronic components may be required on the input to create the required control signal if they are not contained within the SSR package - check the specification to find out what may be needed.
Voltage range: It is necessary to determine the required voltage for the SSR. If DC is to be switched then select a solid state relay with at least 25% greater voltage rating than the maximum voltage anticipated. Ideally a greater margin would improve the reliability.
For AC SSRs, the AC voltage required for the application should be checked - again add a margin. Even though transients are present on many AC lines, AC solid state relays should be able to accommodate these as they are likely to have inbuilt protection (see below), but it is always best to check the specification.
Load current: Apart from the voltage, it is also necessary to know the current that will pass through the device. If too much current flows through the device then it will overheat and could be destroyed.
One point of which to be aware is the inrush current that many circuits exhibit. When first turned on, some items can draw levels of current that far exceed the average current drawn. It is therefore necessary to allow for this when selecting the solid state relay. Typically a multiplier is applied to the average current dependent upon the load which is being switched.
LOAD TO BE SWITCHED MULTIPLIER
Fluorescent lights (AC) 10
Incandescent light bulbs 6
Motors 6
Resistive heaters 1
Transformers 20
The average current to be consumed should be multiplied by the multiplier and the solid state relay chosen with this value for the current.
Dimming: If dimming is required, then some forms of solid state relay are able to provide a dimming function where the output is controlled by the level of the input.
Surge protection: If the solid state switch is to be used with AC, check that it has surge protection built in - most do be best to check. Surge or transient protection is normally provided using metal oxide varistors, MOVs. These metal oxide varistors absorb the transients and prevent them from damaging the SSR.
These points provide most of the major points to be considered when selecting a solid state relay. It is always good to read the whole of the SSR specification to ensure that there are no points that might adversely affect the operation of the overall circuit when in operation.
Solid state relays are ideal devices for many switching applications - they are faster and generally more reliable than electromechanical relays, although they are less resilient to transient spikes and other overload conditions.
In view of their superior operation in many scenarios, solid state relays are used in many circuits, with current and voltage ratings being available for many switching applications.
