Product Features
ABB DSDI115 57160001-NV supports 32 independent digital input channels to monitor the status of multiple devices simultaneously.
ABB DSDI115 57160001-NV supports dry contacts (passive contacts) and wet contacts (active signals), such as mechanical switches, relay contacts, photoelectric sensors and so on.
ABB DSDI115 57160001-NV utilizes opto-electronic isolation between the input channels and the system, with a typical isolation voltage of DC 1500V, to effectively prevent external interference and surge damage.
ABB DSDI115 57160001-NV is equipped with status indicators (LEDs) to show real-time channel status, power failure or communication abnormality.
ABB DSDI115 57160001-NV sets parameters such as input type (normally open/closed), filtering time (to eliminate signal jitter) through software or dip switches.
ABB DSDI115 57160001-NV supports a variety of industrial communication protocols (Profibus DP, Modbus, etc.) and can be seamlessly integrated with higher-level control systems.
Product Using Principle
ABB DSDI115 57160001-NV isolates the external input signal from the internal circuitry via a photocoupler. When the external contact is closed or the signal level changes, the photodiode conducts and triggers the internal circuit to convert to a digital signal (0 or 1). The specific process is as follows:
Signal Acquisition: The status of external devices (e.g. buttons) is input via dry/wet contacts.
Optical isolation: The photocoupler converts the external signal into an optical signal to avoid electrical interference.
Signal Conditioning: Internal circuitry filters, amplifies and level converts the signal.
Digital Output: The processed signals are transmitted to the controller via the backplane bus for logic operation.
Product Parameter
