Product Features
ABB DO801 features 16 independent digital output channels, supporting current source signals, with each channel capable of independently controlling an actuator (such as valves, motor contactors), ensuring no interference between channels and meeting the requirements for parallel control of multiple devices.
ABB DO801 is compatible with PNP/NPN control logic and can switch output modes via software or hardware dip switches.
Each channel has built-in overcurrent protection circuits that automatically cut off output in case of a short circuit to prevent module damage. Channel isolation voltage is 50V, system-to-ground isolation is 500V AC, and it has strong electromagnetic interference (EMC) resistance, making it suitable for industrial environments with strong interference.
ABB DO801 can display the output status in real time (“on” indicates conduction, “off” indicates disconnection), facilitating on-site debugging and fault diagnosis.
ABB DO801 monitors power supply voltage, channel overload/short circuit conditions, and sends alarm signals to the controller via the backplane bus, supporting remote fault localization.
ABB DO801 supports hot-swap functionality, allowing module replacement without system shutdown, reducing maintenance downtime, and enhancing equipment availability.
ABB DO801 operates at a voltage range of 19.2-28.8V DC (typical 24V DC), adapting to power fluctuations in industrial environments to ensure stable output.
ABB DO801 supports relay outputs and transistor outputs (differentiated by model, e.g., DO801-R is relay-type, DO801-T is transistor-type), compatible with different load types:
Relay output: Drives high-current devices and supports dry contact signals.
Transistor output: Drives low-current devices with faster response speeds.
Product Using Principle
ABB DO801 can receive digital commands from the controller via the S800 I/O backplane bus or the Profibus DP protocol.
ABB DO801 can convert digital commands into corresponding switch signals (relay energized/de-energized or transistor on/off).
ABB DO801 can be connected to field devices (solenoid valves, contactor coils) via terminals to control device operations.
ABB DO801 can monitor the status of output channels in real time and transmit status information back to the controller to form a closed-loop control system.
Product Application
ABB DO801 can control the start and stop of machine tool spindles, conveyor belt motors, and pneumatic clamp switches to achieve interlocking of processes in automated production lines.
ABB DO801 can drive the feed valves and stirrer motor contactors of reaction kettles, and work with sensors to achieve precise control of batch production.
ABB DO801 can control the opening and closing of circuit breakers and the start and stop of cooling fans, monitor equipment operating status, and ensure the stability of the power system.
ABB DO801 can control the on/off of water pumps and solenoid valves, adjust water flow direction and flow rate, and achieve automation of wastewater treatment processes.
ABB DO801 can control the on/off of air conditioning units, lighting systems, and access control locks, optimizing building energy management.
