ABB DO880 digital output module

ABB DO880 digital output module

Basic information
Product model: DO880
Brand: ABB
Signal type: 24V DC current source output
Number of channels: 16 channels
Maximum continuous output current: 0.5A per channel
Redundant configuration: Supports single or redundant configuration

Functional characteristics
Loop monitoring and diagnosis: With loop monitoring function, short and open load can be monitored, and the limits can be configured. It can realize no pulse diagnosis of output switch, and has advanced on-board diagnosis function, which can monitor the working status of the module in real time.
Status indicator: The output status indicator light can clearly display the activation/error status, which is convenient for the operator to quickly understand the working situation.
Protection function: The output has short-circuit current limitation and overtemperature protection, and each output channel has a high-voltage side driver with current limitation and overheat protection, which can effectively protect the equipment and circuit.
Fault tolerance and Safety certification: The output driver has a fault tolerance of 1, is certified as SIL3 according to IEC 61508, and is certified as Class 4 according to EN 954-1, which is suitable for scenarios with high security requirements.
Electrical characteristics: The isolation group is isolated from the ground to prevent external interference. Rated insulation voltage 50V, dielectric test voltage 500V AC.

Application field
DO880 can be used in power, petroleum, mine lifting, port, heating, gas, water supply, sewage treatment, metallurgy, paper making, textile, chemical industry, water conservancy and other modern industrial fields. For example, switches used to control electrical equipment in power systems; In the petrochemical industry, it is used to control the opening and closing of valves, the start and stop of motors and other equipment digital control; Used in sewage treatment plants to control the operation of pumps, aeration equipment, etc.
