ABB 216AB61 digital output unit

ABB 216AB61 digital output unit

Functional characteristics
Output channels: Relays with 32 outputs are used to control the output auxiliary relay components to meet the control needs of a variety of devices.
Short-circuit protection: Provides the short-circuit protection function to effectively protect modules and connected devices from short-circuit faults, improving system reliability.
Status indication: The front panel is equipped with an LED to indicate the activated relay, so that the operator can intuitively understand the working status of the relay.

Hardware structure
Space requirements: Occupies a rack partition in a standard 19-inch 6U equipment rack with a compact design that effectively saves installation space.
How it works: In the REG216 digital generator protection system, when the processing unit or other related components send out digital output signals, the 216AB61 digital output unit receives these signals and controls the relay action of the corresponding output auxiliary relay assembly through its 32 outputs, thus realizing the control of external equipment. Such as starting the alarm device, control switching equipment, etc., to achieve the purpose of protecting the generator and related equipment.
