The ASSR-301C-003E is a solid state relay with numerous application fields in many industries such as automation, robotics, motor control, HVAC, and signal-processing applications. It is an ideal choice for controlling resistive loads like light bulbs and heating elements, as well as inductive loads like fans, motors, and solenoids. With its advantages of fast response, low power consumption, and high resilience to shock and vibration, the ASSR-301C-003E is widely utilized in various applications due to its reliability and versatility.

A solid state relay is an electrical switch that is operated by an Electronic Control Unit (ECU). It acts as a digital input-output switch and can be programmed to switch on and off with the application of a voltage or current. Solid state relays feature a Photo-MOSFET, which is an optically isolating analog switch. This switch has gain characteristics which control the switching action of the relay. This solution reduces the amount of electrical noise and electromagnetic interference generated by a mechanical relay.

The ASSR-301C-003E solid state relay is a digital input-output switch operated by the application of a voltage or current. In various applications, different types of voltage will be applied to the unit, such as AC, DC, sine wave, and pulse wave. The output of the ASSR-301C-003E is optical isolation and features a Photo-MOSFET switch that isolates the input from the output, providing forward current to the load. This type of relay can protect the input or output from any interference or voltage spikes that could arise from other sources. The switch is usually operated by either voltage or current.

The power supply requirements of the ASSR-301C-003E are fairly straight forward. The input voltage must be between 0 and 180 volts, while the operating current should be between 10 and 50mA. The state of the device will always be the opposite of the state of the input power. If the power connected to the input is on, the output is off and vice versa.

The basic function of the ASSR-301C-003E is to control the on and off switching times of the device’s output. This can be done using either analog or digital control. By setting the on or off switching thresholds, the user can control either the output voltage or current of the relay. For example, the user can set two thresholds, one with each of the two outputs set with respective outputs being “on” for one and “off” for the other. The user can also use either an analog or digital output control to adjust the switching point.

The ASSR-301C-003E is also capable of performing more complex operations by using a Pulse Width Modulation (PWM) output. PWM allows the user to generate a pulse or square wave with an adjustable duty cycle. This can be used to increase the output voltage or current depending on the output voltage or current sense input. The PWM output can also be used to control the switching timing of the output with higher accuracy.

The ASSR-301C-003E is a reliable and cost-efficient solid state relay for a variety of applications. It is well suited for controlling resistive and inductive loads, providing high speed power switching, high accuracy, and low power consumption with the additional benefits of enhanced reliability and low EMI/RFI emissions. In many control systems, the ASSR-301C-003E is the go-to choice for an efficient, safe, and reliable switch.
