Intrinsically safe Two-Stage Separator SID-1 is a stationary device designed for transmitting two-stage information between intrinsically safe circuits. It is used for separation of intrinsically safe circuits in class “ia” or “ib”. The separator system is supplied by non-intrinsically safe voltage 42VAC or buffer supplied from inbuilt battery.
The input circuit recognizes the “diode contact” stage and generates at the output a signal analogous to the input signal. The separator is a single-channel device with two independent and synchronically operating separated outputs. The outputs simulate “diode contact” and incorporate OPTO-MOS relays. The output circuits may also be used as contacts for resistor dividers in the parameterized line circuits.
SID-1 in the 42VAC power supply unit is an M2 category device with “mb” design, whereas, in the electronic system unit it is an M1 category device with “ia” design.
The application of the separator in energy blocking and cut-off systems will cause the outputs action (cut-off) in the following instances:
The SID-1 separator is a device of M1/M2 category and may thus be used in all underground mines with possible methane or coal dust explosion hazard.
