REMOTE INDICATION INTERFACE TYPE RIS-FS

August 29, 2018

The retrofittable circuit board is used to integrate fault indicators of the FLA3.1 product line into a remote indication system. It provides bidirectional connectivity to all functions of the indicators. The board can be equipped with whether a TTL interface, an RS232 or an RS485 interface for the connection to a remote terminal unit (RTU). Further equipment options are a relay output for notifications, a d-sub DE9 socket and an U.FL connector for external antennas.
Via the Modbus protocol or a customer-specific ASCII-based protocol all functions of the fault indicators of the FLA3.1 product line can be used remotely.

Functions provided for the FLA3.1 product line

- Remote setting of all functions, such as trip current, response delay, reset time, automatic recloser settings etc.
- Remote test and reset
- Remote read-out of line current
- Remote indication of faults. Distinct remote indications for permanent and temporary fault or transient currents.

Special functions for the fault indicators type FLA3.1V and FLA3.1VL:

- Remote indication of voltage or current status
- Datalogging of current read-outs and voltage status
- Remote indication via short transmissions for optimized power consumption
