Functional Characteristics

Output Protection: Each output channel with short-circuit protection, over-voltage protection, and over-temperature protection. ABB DO814 can protect the module and external equipment from damage.

Optical Isolation:：Optical Isolation of ABB DO814 can take advantage of the optical low high barrier, so that the field and control system circuit and the interference from the field environment effectively isolated.

Output status monitoring: Each output channel of ABB DO814 has an output status indication LED, which can intuitively display the working state of each channel.

Process Voltage Supervision: Input for the supervision of process voltage (one per group of output channels). It's going to cause a channel error signal to be generated that can be read over the module bus, if we lose this voltage.

Application Areas

Industrial Process Control: ABB DO814 is also used in industrial process control systems, including the control of valves, pumps, and motors in chemical, petroleum, and other industries. It is able to accurately control the starting - stopping status and running status of these devices in order to ensure the stable operation of the whole production process.

Factory Automation Equipment: In the factory automation production line, ABB DO814 can be used to control the conveyor, robot arm, solenoid valves and other equipment, realize the production equipment accurate control and coordinated operation, improve production efficiency and product quality.

Building Management Systems: ABB DO814 can also be applied to building management systems to realize functions such as controlling door/window opening and closing, air-conditioning system operation, elevator light and other equipment operation, which helps to improve the intelligent management level and energy-saving of buildings.
