Barriers of intrinsic safety with galvanic isolation - barriers of intrinsic safety with galvanic separation of intrinsically dangerous and intrinsically safe circuits, combining a passive (shunt-diode) barrier of intrinsic safety and a signal converter.They are designed to limit the electrical energy supplied to the hazardous area.They provide interfacing of equipment placed in the explosion-proof zone with devices and appliances installed in hazardous areas as separating elements between intrinsically safe and intrinsically dangerous circuits. The barriers are galvanically isolated between channels, input, output and power supply. Explosion protection marking [Ex ia Ga] IIC/IIV, [Ex ib Gb] IIC/IIV.
Do not require earthing. Increased system reliability due to galvanic isolation. Discrete error outputs for each channel.
Transmission of the error signal via TBUS. Power supply connection via TBUS. Wide supply voltage range of 1840 V.
