The BC N2-2R-AR-DC24 interface unit is designed to supply inductive contactless special explosion-proof sensors and to convert the low-current analogue signal from the sensor into an optocoupler signal to control actuators. The interface unit provides: 1. Galvanic isolation of the sensor with the executive device; 2.
Conversion of the low-current sensor signal into the optocoupler output signal to control the executive device with simultaneous indication of the closed output state; 3. Inversion of the channel output state by setting a jumper; 4. Control of the sensor and sensor communication line (short circuit, broken wire); 5.
Light indication and opening of the outputs of the working channel when a fault is detected in it; 6. Formation of the EMERGENCY signal and opening of the emergency channel contacts in case of a fault in the working channel.
