Product Features:
420ma Current Detection: After the module is powered on, the PX is initially displayed and the currently set mode is displayed. At this time, the mode can be adjusted by pressing the "+" and "" buttons. It will enter the realtime display of the measured current after 4s. Three buttons to set the upper and lower limits and function mode selection
Interface Description:
Input
Positive Pole: Connect to the positive pole of the power supply
Negative Pole: Connect to the negative pole of the power supply
AO: 420ma signal input
COM: It is connected to the negative pole of the power supply
Output
NO: NO end
COM: Public
NC: NC end
Several Modes Can be Set as Follows: (Long press "" for 3s to enter the adjustment mode)
P1: Suction exceeds the set value, but is disconnected below the set value; the measured value exceeds the lower limit value and the relay suctions, and disconnects below the lower limit value.
P2: Disconnect when the value exceeds the set value, but is lower than the suction; when the measured value exceeds the lower limit, the relay is disconnected, and the suction is lower than the lower limit.
P3: Suction in the interval and disconnected outside the interval; the measured value is between the upper limit and the lower limit and the relay sucks, otherwise it is disconnected
P4: Disconnected in the interval, sucked outside the interval; the relay is disconnected between the upper limit and lower limit of the measured value, otherwise sucked
P5: Disconnect below the lower limit, and absorb above the upper limit; when the measured value exceeds the lower limit, the relay will disconnect, and the relay will absorb above the upper limit.
P6: Suction is lower than the lower limit, and it is disconnected above the upper limit; the measured value exceeds the lower limit and the relay is suctioned, and the relay is disconnected above the upper limit.
