Description

HIMA  F7101  Digital input module

Functional characteristics:
Hot-swappable function: It supports hot-swappable, allowing for module replacement and maintenance while the system is running without the need to shut down, thereby enhancing the system’s maintainability and availability.
High reliability: By adopting redundant fault-tolerant and self-diagnostic structures, such as a dual redundant fault-tolerant fully self-diagnostic structure (1002D structure), etc., it can effectively detect and handle its own faults, ensuring the stable operation of the system.
Signal processing: It is used to receive digital signals from sensors, switches and other devices, and transmit them to the controller for processing, which can accurately identify the on-off status of digital quantities.

Technical parameters:
Working voltage: 24V.
Working current: 5A.
Number of channels: Generally, it is 4 channels, and multiple digital input signals can be connected simultaneously.
Electrical characteristics: When the 5V DC system power supply fails, the hardware clock and static random access memory (SRAM) on the central module are buffered by the lithium battery on the central module to ensure that data is not lost.

Application fields: Widely used in industrial automation control systems, such as in the chemical, petroleum, natural gas, power, pharmaceutical and other industries, it is suitable for occasions where digital signals need to be collected and processed, providing accurate switch input information for the control system to achieve precise control and monitoring of the production process.
