The RP821048 Power Relay, a solid state relay series, is developed for applications rated up to 2 amperes and in Class I and II systems. Its circuitry responds directly to a digital input signal, providing a stable output for on-state operation. The RP821048 is designed for use in a variety of applications, including: PLCs, Motors, Inverters, Industrial Automation, Process Control, and HVAC.

The RP821048 Power Relay series utilizes an advanced optically coupled isolator to provide isolation between the input and output. This device eliminates the need for external relays and reduces component count. Additionally, the use of a single component minimizes size and offers high isolation voltage (3kV) and creepage distance (3mm). The relay also offers low power consumption (<6W) and fast response time (1ms). Lastly, the RP821048 ensures long-term reliability and operating temperature range of -40°C to +85°C.

The RP821048 Power Relay is designed to be used as a primary switching device for on-state control. This power relay carries a maximum load current of 2 amperes and can withstand voltage up to 5 volts. The input and output circuitry are isolated using an optically coupled isolator which also provides a high degree of noise and surge immunity.

When a digital input signal is applied to the RP821048\'s input, the power relay’s optically coupled isolator will switch the output. This effectively switches a load from a low to a high state. The power relay’s output is stable in the on-state, and is current limited to protect the circuit against over-current damage. The sensitivity range of the power relay is specified over the 0 to 5VDC range.

The internal circuitry of the RP821048 Power Relay also includes an over-temperature protection (OTP) which will shut down the output in case of excessive winding temperatures. This also prevents damage from over-current or thermal issues when dealing with high-power applications. The power relay can be used in series with external devices to further extend the output protection.

The RP821048 Power Relay is an ideal choice for applications that require reliable current switching that is not affected by moisture, high temperature, dust, and vibration. This power relay is robust and designed for long-term durability, and its low power consumption offers greater efficiency. The RP821048 is suitable for a wide variety of applications such as PLCs, Motors, Inverters, Industrial Automation, Process Control, and HVAC.
