Description
SPACOM devices, such as relays and indicator units, are connected to the fiber SPA bus module through bus connections. The bus connects the module SPAZC22-SPA bus for optical signal conversion to RS 485, SPA (+5 V) or RS 232 signals and vice versa. The bus connection module provides a built-in power unit that allows SPACOM devices that need to be disconnected. For example, the bus connection module for service does not interrupt data communication on the optical circuit.
The bus connection module has a 9-pin type D subminiature connector RS 485 or SPA connection, a 25-pin type D connector RS 232 connection and, depending on ordering, two or five pairs of optical connectors with fiber optic cables. Fiber optic links can be fiberglass cables, plastic core cables, or a combination of the two types. The bus connection module is installed in the appropriate position in the instrument cabinet and the module connection cable has been plugged into the D-connector SPACOM device on the rear panel. The bus connection module Type SPA-ZC22 connects to any device that SPACOM is equipped with a Type d connector. The bus connection module can also connect to master units, such as substation level units SACO 148D4 and SRIO 1000M, communication systems.
Function description:
The SPA-ZC22A0B2M Feeder protection Relay is further enriched with additional features to provide more effective protection, extended measurement functions, supervision, control functions and connectivity for your power network. SPA-ZC22A0B2M is primarily used in single bus solutions, using a circuit breaker for various protections.
With prefabricated standard configurations, the device can be used in different types of networks. Typical applications include radially isolated neutral lines, resonant grounding, solid grounding, and incoming and outgoing lines in resistive grounding systems.
The scope of SPA-ZC22A0B2M
Protection, control, measurement and supervision in medium voltage network, and protection of large and medium-sized three-phase AC motors
