ABB AO815 3BSE052605R1 Analog Output HART 8 Ch

ABB AO815 is an 8-channel analog output module designed for industrial automation that provides 4-20 mA signals to control devices such as actuators and valves. It supports precise control and monitoring of various processes. Key features include independent output channels, external and internal error detection (such as insufficient power or output current problems), and module errors for faults such as short circuits or transistor failures.

Fuctions & Features

• 8 analog output channels: The ABB AO815 module has 8 independent output channels that provide 4-20 mA signals and are commonly used to control actuators, valves, and other process devices.

• External channel error: The ABB AO815 reports this error if the process power supply is insufficient or the output current is below the setpoint (when the setpoint exceeds 1 mA).

• Internal channel error: The ABB AO815 triggers this error if the output circuit cannot provide the correct current value.

• Module error: The ABB AO815 reports this error when a variety of faults occur, including output transistor errors, short circuits, checksum errors, internal power supply problems, or watchdog errors.

• HART pass-through communication: The ABB AO815 supports HART pass-through for field communication, allowing communication with HART-enabled devices. Note that only point-to-point communication is supported and the output filter must be enabled for the HART channel.

Specifications
