Specifications

Input in harzadous area

Input signal

Switch contacts/proximity switches

The supply voltage of the sensor

About 8V

Switching rate

≤5kHz

Input/output characteristics:

On site input current

>2.1mA, the output is closed, indicating ON;
When<1.2mA, the output is open circuit, indicating OFF

Input state transition and alarm switch:

When dial switch K1 is at "ON" side, the output state is opposite to the input state.
When dial switch K1 is at "OFF" side, the output state is consistent with the input state.
When dial switch K2 is at "ON" side, the circuit selects indicating red light LFD alarm function.
The dial switch K3 and K4 have no effect for the time being.
