Intrinsically safe Two-Stage Separator SID-2

Product Description

The separator system is supplied by non-intrinsically safe voltage 42VAC and buffer supplied from inbuilt battery. The separator is a two-channel device, each channel has one input and two independent, separated outputs. The inputs circuit recognize the “diode contact” stage and generate at the outputs a signal analogous to the input signal. The outputs simulate “diode contact” or “contact” and incorporate OPTO-MOS relays. Output no 2 of each channel can be controlled by input state or by power state. The output circuits may also be used as contacts for resistor dividers in the parameterized line circuits. The separator can be connected to six independent, separated intrinsically safe circuits.
SID-2 in the AC power supply unit is an M2 category device, 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:

shorting in the input circuit

exceeding of permissible input circuit resistance

power failure

battery discharge (after 24h from disconnection from AC power supply).

 

The SID-2 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.
