HIMA F3221 digital input module

HIMA F3221 digital input module

Electrical characteristic
Power supply voltage: usually 24V DC, allowing a certain range of voltage fluctuations, generally around ±10%, to adapt to different industrial power environments.
Power consumption: Low power consumption, typical values may be around 1-2W, helping to reduce the overall energy consumption of the system.
Input characteristic
Number of input channels: 16 channels, 16 digital input signal sources can be connected simultaneously.
Input signal type: Support dry contact or wet contact input, can receive 24V DC level signal, compatible with a variety of field equipment output signal forms.
Input current: The input current for each input channel is usually in the milliampere-level, such as a typical value of 5-10mA, to ensure reliable detection of the input signal.
Signal isolation: electrical isolation technology is used between the input channel and the internal circuit, and the isolation voltage can generally reach more than 2500V AC, effectively preventing external interference signals from entering the control system, and improving the anti-interference ability and safety of the system.

Functional characteristics
Diagnosis function: With self-diagnosis function, it can monitor the working status of the module in real time. If a fault is detected, it can send an alarm signal through the indicator or communication interface, which is convenient for maintenance personnel to discover and deal with the problem in time.
Filtering function: Usually with software filtering function, the input signal can be filtered, eliminate high-frequency noise and interference, and improve the stability and reliability of the signal.

Working environment characteristics
Operating temperature: The operating temperature range is generally -20 ℃ to + 60℃, which can adapt to different industrial ambient temperature conditions.
Storage temperature: Storage temperature range is usually -40 ° C to + 85 ° C, in non-working state, the module can be stored in a wide temperature range.
Humidity: can adapt to a certain humidity range of the environment, the general humidity requirements of 5%-95%RH (no condensation), in the humid industrial environment can also work normally.
