8922-RB-IS bus isolator

Product Manual：

8922-RB-IS bus isolator is a fieldbus isolation and signal protection module used in industrial automation systems. Its main function is to electrically isolate the fieldbus of the control system, protect the controller and communication equipment from electrical problems such as interference, voltage spikes, and ground loops, thereby improving the overall stability and safety of the system.

Application field

Fieldbus isolation in distributed control system (DCS)

PLC system network signal isolation and protection

On site networking devices in factory automation control cabinets

Anti interference and stability improvement of process automation communication system

Isolation terminal of multi node bus topology structure

Main functions and features

Electrical isolation
Provide isolation protection between the backbone bus and control equipment to avoid ground loops and common mode interference.

Signal protection and filtering
Reduce interference such as noise and voltage spikes on the bus, and improve data communication quality.

Strong anti-interference performance
Industrial grade design that can suppress electromagnetic interference, surge interference, and electrostatic shock.

Supports multiple bus protocols
Can be used in various industrial bus systems (such as fieldbus, serial communication, etc.) to enhance network reliability.

Status indication function
Some models provide LED or status feedback to facilitate on-site inspection of communication status.

working principle

The bus isolator is connected between the fieldbus backbone and the control equipment. The internal circuit of the isolator isolates and buffers the signal. The isolation protection circuit suppresses interference and voltage spikes.
