Digital input: The digital input part of the AD908JQ discrete I/O module is used to receive discrete signals from external devices, such as switch status, sensor status, etc. After these signals are captured by the module, they are converted into a digital quantity that can be recognized by the system for logical judgment and processing by the control system.

Digital output: The digital output part of the discrete I/O module is used to convert the control instructions of the control system into discrete signals and output them to external devices for control. For example, when the control system determines that a device needs to be started, it will send a control signal to the relay through the digital output part of the discrete I/O module, so that the relay is activated and the device is started.

Characteristics and advantages

High reliability: The AD908JQ discrete I/O modules are typically designed for high reliability to ensure continuous and stable operation in industrial automation systems. They can adapt to a variety of harsh industrial environments, such as high temperature, high humidity, vibration and so on.

Fast response time: In order to meet the requirements of real-time control, discrete I/O modules usually have fast input and output response times. This helps ensure that the control system can respond quickly to external events and deal with them accordingly.

A variety of communication interfaces: The AD908JQ discrete I/O module may support a variety of communication interfaces, such as Modbus, Profibus, DeviceNet, etc., in order to exchange data with PLC, DCS or other upper control systems. This allows discrete I/O modules to be easily integrated into various industrial automation systems.

Programmability: Some discrete I/O modules may have a degree of programmability to allow custom configuration and logical operations based on the needs of a particular application. This provides users with greater flexibility and convenience.
