Number of input points: Has 2 numeric input points.

Input voltage: Generally 24V DC, standard 24V DC input signal is acceptable.

Input Current: The input current is small, typically around a few milliamps, to ensure a good fit with commonly used 24V DC power supplies and sensors.

Input Delay: The response time of the input signal is usually in the microsecond range, such as tens to hundreds of microseconds, which can quickly detect changes in the input signal.

Number of output points: Contains 2 digital output points.

Output type: The output type is usually transistor output, which is suitable for application scenarios that require high-speed switching action, and its switching speed is fast.

Output voltage: The operating voltage range generally covers a wide range, such as 12V to 24V DC, which can be flexibly configured according to actual usage.

Output current: The rated current of each output point is usually around 0.5A, which can drive some small loads, such as small relays, indicator lights, solenoid valves, etc

Interface type: The I/O bus interface matching the ABB AC500 series is used to ensure a reliable connection between the module and the main controller, and to achieve high-speed and stable data transmission.

Isolation voltage: There may be a high galvanic isolation voltage between the input and output channels and the internal circuitry, such as 1500V AC, to prevent external electrical interference and ensure the safety and stability of the module.

Operating temperature range: typically between -25°C and +60°C, able to accommodate the temperature conditions of most industrial environments.

Relative humidity range: It can generally operate normally at a relative humidity of 5% to 95%, but condensation is not allowed to avoid short circuits or other electrical faults in the internal circuitry.

Rating: Typically IP20, it protects against larger objects such as fingers for most industrial site installations, but protection against dust and moisture is relatively limited and may require additional protection in harsh environments.

Status indicator: With input and output status indicators, it is convenient for users to intuitively check the status of the input signal and the activation of the output signal, which is convenient for on-site debugging and troubleshooting.

Diagnostic function: It has certain online diagnosis capabilities, which can detect and report abnormal conditions in the input and output channels, such as input signal loss, output short circuit or open circuit and other faults.

Mainly designed for ABB AC500 series PLC, it has good compatibility with the main controller and other modules of this series, and can be seamlessly integrated into the ABB AC500 series automation control system to jointly realize various industrial automation control tasks.
