ABB 3BHE03197R0001 medium voltage frequency converter

Voltage: commonly 24V DC (direct current) or 110V/230V AC (alternating current). 24V DC is commonly used in industrial automation systems, with high safety and strong 

anti-interference ability; 110V/230V AC can be directly connected to common mains power networks.

Power: The power level varies depending on the module's functionality. If it is a simple signal processing module, the power may be a few watts, such as 5W-10W; If the 

module has complex computing and communication functions, the power may reach tens of watts, such as 20W-50W.

input/output signal

Digital input: There may be 8-16 channels, and the input signal level is generally 24V DC. It can receive switch signals, such as on/off signals from sensors, trigger signals from 

buttons, etc.

Digital output: There are also 8-16 channels, and the output type may be transistor output or relay output. The transistor has a fast output response speed and is suitable for 

high-frequency control applications. The load current is generally in the range of a few hundred milliamps; Relay output can withstand large load currents, up to several 

amperes, and is commonly used to control equipment such as solenoid valves and contactors.

Analog Input/Output: Analog input channels may support common signal ranges such as 0-10V and 4-20mA, used to collect continuously changing physical quantities such 

as temperature, pressure, and flow rate. The analog output channel can also output signals within the corresponding range to control actuators such as regulating valves 

and frequency converters.

response time

The response time of digital input and output is usually in the millisecond range, such as 1-10ms, to ensure quick response to external signal changes.

The response time of analog signal processing may be slightly longer, ranging from tens of milliseconds to hundreds of milliseconds depending on the complexity and 

accuracy requirements of signal processing.

accuracy

If analog processing is involved, the accuracy of analog input and output may reach ± 0.5% - ± 1%, ensuring the accuracy and reliability of the collected and output signals.

In terms of control functions, such as position control, speed control, etc., the control accuracy may vary depending on the specific application requirements, and may reach ± 0.1% - ± 1%.

Communication interface: may be equipped with Ethernet interface (RJ45), supporting standard Ethernet protocols such as TCP/IP, to achieve high-speed data transmission 

and remote monitoring; There may also be an RS-485 interface for serial communication between devices, with a longer communication distance; It may also have fieldbus 

interfaces such as Profibus, Modbus, etc., which facilitate network communication with other industrial devices.

The communication speed of Ethernet can generally reach 10Mbps or 100Mbps.

The communication rate of RS-485 may range from 9600bps to 115200bps depending on the specific device and application scenario.

The communication speed of fieldbus varies depending on the protocol, for example, the communication speed of Profibus can be selected between 9.6Kbps and 12Mbps.
