The ABB DI810 3BSE008508R1 is a digital input module from the ABB S800 I/O series.It is primarily used for acquiring low-voltage digital signals(such as sensor and switch status)in industrial automation systems and is widely compatible with control systems such as ABB Ability™System 800xA.The following are its details:
I.Basic Parameters
Channel Configuration
Number of Channels:16 digital input channels,divided into two groups of 8 channels each,supporting independent signal acquisition.
Input Type:Compatible with both dry contacts(passive)and wet contacts(active signals),supporting both normally open and normally closed contact inputs.
Electrical Parameters
Input Voltage:Rated 24V DC,voltage range 18-30V DC(accommodates industrial power supply fluctuations).
Input Current:Typical 6mA at 24V DC.The low-power design reduces signal source load.
Input Impedance:3.5kΩ(Stable impedance ensures accurate signal acquisition).Isolation and Safety
Isolation:Electrical isolation between the two channels,as well as isolation between the channels and the module bus and ground,provides strong anti-interference capabilities.
Insulation Level:Rated insulation voltage 50V,dielectric test voltage 500V AC(1 minute),meeting industrial safety standards.
II.Features
Fast Response and Filtering
Response Time:Signal switching response time is less than 1ms,meeting the requirements of high-speed control scenarios(such as real-time production line monitoring).
Configurable Filtering:Supports digital filter time adjustment(2ms,4ms,8ms,and 16ms),which can be set based on the on-site electromagnetic environment to effectively filter out noise pulses.
Status Indication and Diagnostics
Each channel is equipped with an independent green LED indicator that displays the input status in real time(lit for”1″and off for”0″),allowing intuitive verification of channel operation.
Each channel has a built-in voltage monitoring function.When the power supply voltage is abnormal,an error signal is fed back via the module bus,facilitating remote diagnosis.Protection Features
Each channel features integrated current limiting components and EMC protection circuitry,providing overcurrent protection and electromagnetic interference immunity,making it suitable for industrial environments with strong electromagnetic fields(such as those near motors and inverters).
Environmental Adaptability
Operating Temperature:-20°C to+60°C(wide temperature design,suitable for high and low temperature industrial environments);Storage Temperature:-40°C to+70°C.
Protection Rating:IP20(must be installed in a control cabinet);Vibration and shock resistance meet IEC 61131-2 standards.
III.Physical and Compatibility
Dimensions and Weight:45mm wide×119mm high×102mm deep(111mm including connectors),weighing approximately 0.2kg,suitable for space-saving installation in dense control cabinets.
Power Consumption:Typical 3.5W.Low heat generation design extends module life.Compatibility:Supports pairing with ABB S800 I/O series terminal units(such as TU810,TU812,TU830,etc.),and access to control systems via PROFIBUS DP,MODBUS,and other protocols for distributed signal acquisition.
