    Motion control follows conventional algorithms that take each transitional point as a tuple in the Cartesian space. Basically, each motion point is handled as X and Y coordinates; a hardware example could be an X-Y table. While this approach is simple and easy to implement, it can become redundant by adding too many repetitions in the controller’s (e.g. PLC) code.

    Relay Contact Gap One of the most important considerations for applications that require high surge voltage protection is relay contact gap.  This is because the greater the distance between contact terminals, the higher surge voltage the Relay can withstand. Therefore, a safe contact gap distance provides protection from short-circuit conditions that could damage your product.

    Avoiding Measurement Errors   It is always disheartening to find out after hours of data logging and subsequent statistical analysis, that your measurements are not good enough. For example, an average temperature for a PID set point may have an error that causes an oven to melt numerous parts in a batch. How can these types of errors be avoided? This is where the critically acclaimed standard deviation comes into consideration.

    LED Current And PhotoMOS Lifespan Panasonic PhotoMOS Relays are well known for their extremely long lifespan. However, there is a caveat - engineers must take into consideration the LED current when incorporating PhotoMOS in their designs. Let's take a look at how LED current defines a PhotoMOS Relay lifespan. LED Characteristics The LED life curve below shows LED power getting lower in proportion to the number of hours of use. It is not the number of operations, but the number of hours the LED current is applied.

    PhotoMOS Relays And Battery Monitoring PhotoMOS Relays can be used to monitor battery charge, which in turn can extend battery life and avoid hazardous situations. Battery monitoring is highly useful for Uninterruptible Power Supply (UPS) applications because they need to be reliable. The UPS is only as reliable as the batteries are healthy and able to provide proper back up power when needed.

    Pilot Duty Ratings A Relay can be assigned a Pilot Duty Rating when it is used for switching loads on another relay, or solenoid valve coils. It can be a direct current (DC) rating, or an alternating current (AC) rating, as shown in the table at the bottom of this post. The Pilot Duty Ratings are obtained after performing product qualification tests.  These tests are performed at the voltage and current values provided using the information in Table 1 below, with a 0.35 power factor.

    Thermal Electromotive Force Over the years, test and measurement companies have sought for a feature in relays that provides an accurate reading at low current. This is important because at very low current, there is a tendency for inaccurate measurements to occur, thus causing false readings. This feature is referred to as Thermal Electromotive Force (EMF), and is found in a few relays.
