Core Functions
Signal Conversion and Output: Converts digital signals sent by the controller into analog signals of various specifications, including voltage signals (such as bipolar voltages like -10V to +10V, and unipolar voltages like 0V to 5V/0V to 10V) and current signals (0mA to 20mA, 4mA to 20mA), adapting to the signal receiving requirements of different analog control devices.
Flexible Configuration: The module is equipped with 2 configurable analog output channels which are all in the same group. The signal type of the output channels can be flexibly set according to the requirements of on-site equipment, meeting the adaptation needs of diverse control scenarios.
Status Monitoring and Fault Diagnosis: Fitted with 2 yellow LED indicators corresponding to the 2 analog output channels respectively, it can intuitively display the signal status of each channel, facilitating technicians to quickly judge the normal operation of the channels and detect and troubleshoot faults in a timely manner.
Anti-interference and Isolation Protection: Adopting advanced anti-interference design and photoelectric isolation technology, the module has an electrical isolation grade of ≥2.5kV. It can effectively resist electromagnetic interference in industrial sites, and prevent external circuit faults from affecting the module and the controller, ensuring the stable operation of the system.
Wide Temperature Adaptation: A W-type version for extended temperature range is available, which can meet the temperature adaptation requirements in different regions and industrial environments, enhancing the applicability of the module in harsh environments.
Technical Parameters
Analog Output Performance: Equipped with 2 output channels, all of which feature a 12-bit signal resolution (including the sign bit for bipolar voltage signals; the same 12-bit resolution applies to unipolar voltage and current signals), ensuring high precision of analog signal output and minimizing control errors.
Power Supply Mode: Supports internal power supply obtained via the I/O bus, and can also be connected to an external power supply through the terminals L+ (24V DC process voltage) and M (0V DC). The M terminal is connected to the CPU's M terminal via the I/O bus, ensuring the stability and flexibility of power supply.
Electrical Connection: Adopts a 6-pin terminal block for the transmission of analog output signals and power supply connection, with clear wiring specifications that facilitate on-site installation and maintenance and reduce the risk of wiring errors.
Operating Environment: The standard operating temperature range is -20°C to +60°C, and the W-type version is adaptable to a wider temperature range. It has excellent vibration and shock resistance performance, complying with the environmental adaptability standards for industrial-grade equipment and being able to cope with the harsh conditions of complex industrial sites.
Communication and Compatibility: Realizes data interaction with the controller via the I/O bus, and can be connected to the CPU through components such as TB850/CI854. This ensures stable communication with ABB System 800xA/AC 800M controllers and the real-time transmission of control commands and status feedback.
Application Scenarios
The ABB LT9673a (HESG446076R1, HE663599-31813) analog output module is widely used in process industries such as petrochemicals, power generation, metallurgy and papermaking. For example, in petrochemical production, it can be used to adjust the opening of flow control valves, and control valve actuation by outputting precise 4mA - 20mA current signals to achieve accurate regulation of material flow. In power systems, it can work with controllers to adjust the excitation current of generators, ensuring the voltage stability of power generation systems. It is also suitable for various automation systems that require closed-loop control of actuators via analog signals, helping users improve the automation level and control precision of production processes.
