The ABB DO828 is a digital output module with the following product details:
Basic Parameters
Number of Channels:16.
Output Voltage:5-250V AC and 5-125V DC.
Output Current:Maximum output current per channel is 2A.
Isolation:All output channels are individually galvanically isolated.
Dimensions:45mm wide,102mm deep,119mm high.
Weight:Approximately 0.3kg.
Rated Insulation Voltage:250V.
Dielectric Test Voltage:2000V AC.
Power Consumption:Typical 3.5W.
Operating Temperature Range:Typically-40°C to 70°C,similar to the similar DO820 module.
Features
Status Indicator:The module features indicators for Fault(F),Run(R),and Output Preset(OSP).Each output channel also has a status LED to provide a visual indication of the channel’s operating status.Output Preset State(OSP):When an error is detected,OSP sets the output to a predetermined state,ensuring system safety and stability.
Relay Power Supply Voltage Monitoring:This module monitors the 12V relay power converter.If the voltage drops,an error signal is generated,illuminating the warning LED.This error signal can be read via the module bus.This monitoring function can be enabled or disabled via a parameter.
Compatibility:Requires the TU851 module terminal unit.
Application Scenarios
This module is widely used in industrial automation,building automation,and process control,and can be used to control motors,solenoids,valves,lights,and other devices.
