70-OAC5A

I/O Relay Modules

70-OAC5A is a type of I/O Relay Module typically used for industrial automation applications. It leverages an independent input pair (12-24V DC) and output pair (750/1500W) for a wide range of applications. It is designed to provide reliable control mechanisms for two independent sets of contactors and up to two switching elements, with an electromechanical (spark-over protection) equipped for both input voltage and output current, and a selection of LED status indicators to provide further visibility. It is a field-level device, meaning that it can be installed in a variety of wiring systems and environmental conditions.

Working Principle

The 70-OAC5A operates by providing reliable control mechanisms for two separate circuits. For the input voltage, the device is equipped with an electromechanical (spark-over protection) to protect against over voltage or short circuit. On the output side, the device is also equipped with a spark-over protection unit, as well as current monitoring contacts, which keep the device from connecting dangerous voltage levels. Additionally, the device is designed with an OFF-delay function, which makes sure that the relay is energized no more than three seconds after the pulse signal is given.

In operation, the 70-OAC5A triggers a circuit once the input voltage is applied. The spark-over protection unit ensures that the voltage does not exceed a certain limit. On the output side, the spark-over protection unit ensures that only a safe voltage is applied, and the current monitoring contacts ensure that dangerous voltage levels are not applied. Furthermore, the OFF-delay function also ensures that the relay is energized only after the pulse signal has been applied.

Application Field

The 70-OAC5A is most commonly used in industrial automation applications, such as material handling or process control. Due to its reliable control mechanisms and independent input and output pair, it can easily be integrated into many existing systems, or be used as a standalone device. Additionally, due to its design, it is also suitable for a wide variety of wiring systems and environmental conditions.

Examples of applications where the 70-OAC5A would be suitable include material handling machines, conveyors, lifting systems, and manufacturing equipment. In these cases, the device would provide reliable control mechanisms for the systems, ensuring the safety of all involved personnel and equipment. Additionally, the independent input and output pairs also allow for independent control of both circuit inputs and outputs.

Conclusion

The 70-OAC5A is a type of I/O Relay Module typically used for industrial automation applications due to its reliable control mechanisms and independent input and output pair. It is designed to provide reliable control mechanisms for two independent sets of contactors and up to two switching elements, with an electromechanical (spark-over protection) equipped for both input voltage and output current, and a selection of LED status indicators to provide further visibility. It is a highly versatile device, and can be used in a variety of wired systems and environmental conditions, making it suitable for a range of applications.
