The IS420YDOAS1B discrete output I/O package can control up to 12 relays, accept feedback specific to the terminal board, and send inputs through RJ45 connectors. This I/O package can be used with ControlST software that supports V06.01 or higher and V05.00 firmware.
Product Description
The discrete output I/O package IS420YDOAS1B can provide electrical interfaces between up to two Ethernet input/output networks and discrete output terminal boards. This package can control up to 12 relays and receive feedback specific to the terminal board. All inputs of the I/O package will be sent through a dual Ethernet RJ454 connector and a three pin power input. The DC37 pin connector is used for output and is directly connected to the relevant terminal board connector. If visual diagnosis is required, it will be provided through the LED indicator light on the front of the packaging.
As mentioned above, the IS420YDOAS1B I/O package can provide diagnostic LEDs; Usually, 12 LEDs are yellow to indicate that the command is energizing each output of the relay. The BBPx processor LED will also be used to indicate the required diagnostics. The ATTN LED indicator light is red or green, constantly on or flashing. Some modes of green ATTN LED are 2 Hz 50% and two 4 Hz pulses every four seconds; The latter mode indicates that the application is online and running as needed.
During the runtime of the IS420YDOAS1B package, various common diagnostic alerts may pop up, such as two, three, and five. All of these alarms have different causes and solutions. The description, causes, and possible solutions for alarm five are that the I/O package is in remote I/O mode, partly due to hardware failures and module configuration. To fix these errors, please completely replace the I/O package or module, or rebuild the system and reconfigure the I/O package.
The IS420YDOAS1B discrete output module is an important component in industrial automation and process control systems, mainly used to convert control signals into corresponding output signals, thereby achieving precise control of equipment. Its main function is to provide energy for output devices such as motor starting coils, indicator lights, solenoid valves, etc. connected to its terminals. When the processor stores a specific binary number (such as “1”) at a specific address in memory, the module activates the corresponding output device.
There are various types of IS420YDOAS1B discrete output modules, including AC and DC types, which can provide a wide range of voltage outputs. In addition, these modules are usually equipped with status indicator lights to display the working status of each independent output terminal. Some modules even have two status indicator lights configured for each output, one called a logic indicator light and the other called an output indicator light. When the logic indicator light is on, it indicates that the processor has logically connected the output device; When the output indicator light is on, it indicates that there is actual current flowing into the output device.
In addition to industrial automation, discrete output modules also play important roles in computer science, control, automation, embedded systems, network communication, e-commerce, and big data processing. For example, in computer science, the output module outputs program results to devices such as computer screens and printers, helping users obtain computer processing results; In the field of control, output modules are used to output control signals and control the motion and status of various devices.
In addition, compared to continuous control systems, discrete control systems have advantages such as simple modeling, convenient implementation, high flexibility and variability, and strong anti-interference ability. Therefore, the application of discrete output modules is widespread, which can significantly improve the efficiency and reliability of the system, bringing more convenience and security to people’s lives and work.
Comment on IS420YDOAS1B
The IS420YDOAS1B I/O board is compatible with various relay output terminal boards, such as TRLYS1B and SRLYS2A boards, each with different functions, but none can be used for dual redundant applications. For more information on compatible terminal boards, please refer to GEH-6855 Volume 2 System Guide.
