ABB SPA-ZC22 Bus connection module

ABB SPA-ZC22 Bus connection module

Main functions

The ABB SPA-ZC22 Bus Connection Module is mainly used to connect secondary devices in substations to the SPA (Substation Protection Area) bus. It is able to convert electrical signals (e.g. TTL or RS 485 signals) from the host device into optical signals for the bus and vice versa. This conversion function enables various devices in the substation to be interconnected via a fibre optic loop, thus enabling high-speed transmission and sharing of data.

Technical features

Optical-electrical conversion function: The module has a built-in optical-electrical converter, which is capable of converting electrical and optical signals into each other to ensure stable data transmission on the bus.

Strong resistance to electrical and electromagnetic interference: due to the use of optical fibre as the transmission medium, the module has a very high resistance to electrical and electromagnetic interference, and is able to operate stably in harsh industrial environments.

Easy installation: The module is designed with ease of installation in mind, allowing users to easily install and configure it as needed.

Multiple Loop Support: The SPA-ZC22 module supports the connection of multiple fibre optic loops, which helps to increase the number of fibre optic loops in the substation and improve the reliability and flexibility of the system.

Multiple interfaces: The module provides multiple interface options, such as RS 232 C interface and RS 485 interface, these interfaces can be used to connect to computers, modems and other devices to meet different communication needs.
