ABB AO845A analog output module

ABB AO845A analog output module

Electrical parameters: Input voltage and output voltage are 24V DC, output current is 1A. With 8 unipolar analog output channels, the signal type is usually 4-20mA current output, and the load resistance that can be driven generally meets the requirements of the corresponding current output.
Performance parameters: The compact design enables fast and accurate processing of digital signals. The module performs a self-diagnosis cycle and has a variety of diagnostic functions to report external channel errors, internal channel errors, module errors, etc. For example, an external channel error is reported when the process power supply providing voltage to the output circuit is too low, or when the output current is less than the output setpoint and the output setpoint is > 1mA (open circuit); If the output circuit cannot give the correct current value, an internal channel error will be reported; Module errors are reported when output transistor errors, short circuits, checksum errors, etc.

Environmental parameters: The operating temperature range is -25 °C to + 70°C, the protection level is IP20, and it can be used in some industrial environments with certain dust or non-harsh humidity.
Application: Applicable to the field of industrial automation, widely used in automation control, robots, power systems and other scenarios, can be used for the output of digital signals to help achieve automatic control and optimize production efficiency.
Other features: Suitable for single or redundant applications, with a set of 8-channel isolation from ground, analog input short-circuit protection to ZP or + 24V, support for HART direct communication. The module is also cost-effective, highly modular, and supports the industry-standard fieldbus PROFIBUS DP, as well as non-ABB controllers, as well as ABB’s Advant Fieldbus 100. Can be configured transparently as part of the relevant controller, just like local I/O, with no additional knowledge or skill required, and comprehensive diagnostics, module hot swap, and redundancy solutions help maintain product performance.
