The SO-54SR-111-REK has protections, measurement, control, telemetry, automation functions and may operate as a multi-channel event recorder and is used to support the THO-RC27 automatic overhead recloser circuit-breaker. The controller is built in the SRC-1 control unit, dedicated to the THO-RS27 circuit-breaker. The SO-54SR-111-REK is equipped with a dedicated panel casing. It has a dispatcher’s panel consisting of a graphic terminal with the LCD touch screen, module with 8 LEDs to which any binary signal from the controller database may be assigned, control LEDs – "Operation" and "Error" and ON/OFF buttons.
The SO-54SR-111-REK controller is also equipped with the following communication ports:
- RS-232 interface
- RS-485 interface
- serial channel with multi-mode fiber-optic 650µm or 820µm
- Ethernet 10/100Base-TX
The controller is equipped with a multi-channel disturbance recorder which enables to record oscillograms of analog values, measured and calculated, binary states representing inputs and outputs as well as internal states of the controller itself. The controller disturbance recorder may be triggered by an event, operation or signalization of each protection component and switching on a circuit-breaker.
The controller has the following resources:
- 3 analog inputs to measure currents from Rogowski’s coils
- 6 analog inputs to measure voltages
- 16 binary inputs - 24V DC
- 4 control outputs - 8A/24V DC, 0.25A/220V DC
The device is configured using a dedicated program, pConfig. Apart from the configuration, the software enables to preview operation state, binary and measurement databases, read the event log and disturbance recorder. [-]
