Description
NEW OPEN BOX CONDITION
The ABB SPA-ZC 101 is a type of bus connection module used for connecting substation secondary devices to the SPA bus system. These modules convert the electrical signals (like TTL, RS485, or RS232 as seen on the device) of the host device to fibre-optic signals for the bus, and vice versa.
- Function: Converts electrical signals to optical signals for communication over a fibre-optic loop.
- Interfaces: The module provides interfaces for RS485, TTL, and RS232 communication levels.
- Connectivity: It typically uses a 9-pin D-type connector for the host device and a pair of optical transceivers for the SPA bus.
- Power: The module can be powered by +5V, +8V, or +12V DC power supplies.
- Application: Used in industrial automation and power systems to enable communication between various devices and systems, such as protective relays
