The HIMA F3 DIO 20/8 02 is a digital input/output module applied to industrial automation and safety - related control systems. Here is its detailed information in English:
The HIMA F3 DIO 20/8 02 is designed for use in safety - critical applications where reliability and efficiency are crucial. It can be used together with safety - related controllers and I/O modules from the HIMatrix series, as well as fast and secure Ethernet safety - related communication, to build an ideal foundation for small and medium - sized systems. It is widely used in industrial automation and safety control systems that require high reliability and stability, such as chemical, petroleum, natural gas, power and other industries.
- I/O Channels: It has 20 digital input channels and 8 digital output channels, all non - galvanically separated.
- Input Signal Type: The input voltage range is 15 - 30 VDC, and the response time is ≥ 10 ms.
- Output Signal Type: The module has 8 digital outputs. At the maximum ambient temperature, outputs 1 - 3 and 5 - 7 can be loaded with 0.5 A each; outputs 4 and 8 can be loaded with 1 A or with 2 A at an ambient temperature of up to 50 °C. Within a temperature range of 60 - 70 °C, all outputs can be loaded with 0.5 A. If an overload occurs, one or all digital outputs are switched off and will be switched on again automatically when the overload is removed.
- Power Supply: Usually 24 VDC (input voltage range may vary slightly depending on specific models and application requirements).
- Operating Temperature: - 40 - + 70 °C.
- Humidity Range: 5 % - 95 % RH (non - condensing).
- Vibration and Impact Resistance: It can withstand 0.05 g rms (random) vibration and 15 g (half - sine) impact.
- Protection Level: IP20.
- Redundant Design: This module adopts a redundant design, which ensures the continuous operation of the system even if a single channel fails, improving the reliability and stability of the system.
- High Channel Density: With 20 digital channels in total, it is suitable for connecting various field devices such as sensors, actuators, and switches, meeting various application needs.
- Built - in Diagnostic Function: The module has a built - in diagnostic function that can continuously monitor the operation status of the module and detect potential faults, helping users discover and solve problems in a timely manner.
- Hot Backup Function: Allows for online replacement of faulty modules without interrupting system operation, reducing maintenance time and costs.
For the external wiring and the connection of sensors, the de - energized - to - trip principle is applied. Thus, if a fault occurs, the input signals adopt a de - energized, safe state (low level). If the device detects a fault on a digital input, the user program processes a low level in accordance with the de - energized - to - trip principle, and the device activates the fault LED. In addition to the channel signal value, the user program must also consider the corresponding error code, which allows the user to configure additional fault reactions in the user program.
