Discrete signals and alarms recording device
«ORION» ARS is designed to indicate the operation of relay protections(RP) and emergency control schemes(ECS), shunting high-resistance input sensors of microprocessor terminals, implement the received information to the terminals, as well as to the centralized alarm system of a power facility. Functionally it completely replaces outdated signaling devices (RU-21, REU-11, ES, etc.).
"ORION" ARS is used at power facilities as part of RP and ESC with a large number of control and information signals:
- transmitters and receivers of APK "ORION", AKA "Kedr",
- «UPK-C», «AKPA-B», АES600(ETL600) etc.,
- emergency control schemes;
- autotransformer protections, high voltage circuit breakers automation, etc..
Device functions:
- operation of input discrete signals exceeding a specified voltage (current) threshold, with a duration longer than a specified interval;
- triggered discrete inputs on device screen;
- event log in the non-volatile memory;
- ability the received information implement to an external registrar and (or) to the local information network of the object. Interfaces: RS 485/422, optical;
- processing of the received information for implementation with the help of output relays to the terminals of relay protection, automation, control, as well as to the central signaling of the object.
