CKM0620 is an optoelectronic isolated SPST-NO (single pole single throw normally open) solid state relays (SSRs). This type of relays are frequently used in many industrial applications due to its wide operational temperature range, reliability and long life. It is based on the principle of light activated thyristors (LASCRs).

An SSR consists of light emitting diode (LED) and light sensitive semiconductor (LASCR). The LED is driven by an external power source to emit light every time it is switched on. This light is then incident on the LASCR, which switches on and off according to the varying intensity of the incident light. This switching operation controls the output load through a mechanical mechanism.

The CKM0620 series of optically isolated solid state relays offers an economical solution for a wide variety of industrial and consumer applications. It has a switching current range of 2A and a voltage range of 200V AC to 240V AC. It also has low power consumption and is capable of operating at temperatures ranging from -40°C to +85°C.

CKM0620 SSR is a three terminal device, which comprises of input (LED portion), output (LASCR portion) and common terminal. The input port is connected to the power source of the application which in turn provides power to the LED. When the LED is energized, it emits light and this light in turn falls on the output port of the CKM0620. This light triggers the LaSCR and the output port is energized with the same voltage and current available at the input port.

CKM0620 solid state relays are widely used in industrial applications such as temperature control circuits, process controls, motor controls, HVAC systems, motor drives, lighting control systems, electronic energy meters and other such applications.

The CKM0620 SSRs provide excellent performance in terms of power saving, operational reliability and long life. It has the ability to switch on and off rapidly, which it makes ideal for use in motor drives and other similar applications. It also has an adjustable LED dimmer that allows the user to control the amount of light incident on the output port and hence control the output load.

In addition, the CKM0620 SSRs have a built-in Zener diode which eliminates the possibility of cross-conduction or output shorts. This feature ensures that the overall sensitivity limit of the device is not exceeded. Furthermore, the design of the device is such that it can withstand transient voltage and current spikes.

In conclusion, the CKM0620 optoelectronic isolated SPST-NO solid state relays is an reliable, cost effective and widely used device. It can provide excellent performance in a variety of industrial applications needing on/off switching, process control, motor control, lighting control and many other control applications.
