ABB 3HAC5497-1 Bus cable DB25

ABB 3HAC5497-1 Bus cable DB25 is a bus cable designed for industrial automation systems. It uses a DB25 interface (25-pin connector) and is mainly used for signal transmission or bus communication between devices. The following is a detailed introduction:

Function and application

Signal transmission

Used to connect industrial controllers, robot systems, sensors, drives and other devices to transmit digital signals, control signals or bus data (such as communication between PLC and robot controller).

Supports serial communication (such as RS-232/RS-485) or parallel data transmission, suitable for industrial scenarios that require stable connection.

Typical application scenarios

Robotic system: connect ABB robot controllers (such as IRC5) and peripheral devices (such as teach pendants, IO modules, sensors) to transmit control instructions or status signals.

Automated production line: establish communication links between PLC, inverter, servo system and other devices to achieve system integration and collaborative control.

Test and debugging equipment: used for debugging interfaces (such as serial port debugging) or peripheral device expansion (such as printers, programmers) of industrial equipment.

Technical Features

Interface and Specifications

Connector Type: Both ends are DB25 interfaces (male or female, to be confirmed according to actual needs), using standard 25-pin pin definition, supporting custom line sequence or following industry standards (such as RS-232 DTE/DCE pin assignment).

Cable Material: Multi-strand twisted copper wire is used inside, and the outer layer is wrapped with a shielding layer (such as aluminum foil + braided mesh). It has strong anti-electromagnetic interference (EMI) ability and is suitable for high-frequency signal transmission in industrial environments.

Length: Common specifications are standard lengths (such as 1 meter, 3 meters, 5 meters), and some models support customization.

Electrical Characteristics

Transmission Rate: Supports low-speed to medium-speed data transmission (such as RS-232 up to about 115.2 kbps, RS-485 can reach several Mbps), depending on the protocol and cable length.

Impedance Matching: The cable impedance matches the interface circuit to reduce signal reflection and attenuation, ensuring the stability of long-distance transmission.

Protection level: The outer layer is made of wear-resistant PVC or rubber sheath, which is oil-resistant and bend-resistant, and can adapt to mechanical stress and chemical corrosion in industrial environments.

Installation and precautions

Installation method

Directly insert the corresponding port of the device through the DB25 interface, and use screws to fix the connector to ensure a stable connection and avoid poor contact caused by vibration.

If used for bus communication (such as RS-485 network), pay attention to the configuration of the terminal resistor (in some scenarios, 120Ω terminal resistors need to be connected at both ends of the bus).

Precautions for use

Pin definition: The function of the DB25 interface pin must be consistent with the device manual (such as ABB robot system may have specific pin assignments). Incorrect wiring may cause device damage or communication failure.

Shield grounding: Ensure that the shield layer is reliably grounded to enhance anti-interference ability. The grounding end is usually connected to the device housing or system ground.

Environmental adaptability: Avoid naked use in high temperature, strong electromagnetic interference (such as close to inverters, motors) or humid environments. If outdoor or harsh environments are required, protective sleeves or cables with higher protection levels are required.
