Central substation annunciator
The SC-16 device is dedicated to visual (by LED) indicating of information received by its binary inputs. In particular it can be: signals informing about trips or any other disturbances occuring within supervised station which are critical to quick assesment of situation by the staff. SC-16 is freely programmable device – each diode can be assignet to any input or group of inputs. Also, each signal can be multiplied by relay outputs of the device. The device cooperates with substation telecontrol system and is equipped with event recorder. SC-16 is equipped with fiber-optic communication port, RS-485 or Ethernet for communication with supervision system purposes. The communication is fulfilled by following protocols: ZEG (with SMiS software) or IEC 60870-5-103. Optionally protocols MODBUS or DNP-3 are also available.
