with led Current Detection Sensor Module Digital Display 4-20mA Relay Module Component DC12V
Specification:
Item Type: Current Detection Sensor Module Material: PCB
Working Current: Standby: 12mA, Working: 56mA
Working Voltage: DC12V
Digital Display Life: Greater than or equal to 50,000 hours
Relay Life: Less than or equal to 100,000 times
Digital Tube: 3 in 1

Detection : 4-20ma
Product Features:
4-20ma 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 real-time 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: 4-20ma 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
P-1: 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.
P-2: 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.
P-3: 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
P-4: 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
P-5: Disconnect below the lower limit, and absorb the upper limit; when the measured value exceeds the lower limit, the relay will disconnect, and the relay will absorb the upper limit.
P-6: Suction is lower than the lower limit, and it is disconnected the upper limit; the measured value exceeds the lower limit and the relay is suctioned, and the relay is disconnected the upper limit.
Setting Instructions for The Convenience Of Description, Use K1 For The setting key, K2 for the + key, and K3 for the-key:
Key Description: "K1 /adjust; K2+; K3-/mode selection
Press the K1 key, the first digit flashes, adjust the lower limit of hundreds, press K2, K3 to adjust 0~1 change
Press the K1 button, the second digit will flash, adjust the tens digit of the lower limit, press K2, K3 to adjust 0-9 changes
Press K1 key, the third lower third digit flashes, adjust the lower limit one digit, press K2, K3 to adjust 0-9 change
Press the K1 key, the 4th, lower, and fourth digits will flash, adjust the upper limit of hundreds, press K2, K3 to adjust 0~1 changes
Press K1 key, the 5th bottom fifth digit flashes, adjust the upper limit ten digits, press K2, K3 to adjust 0-9 changes
Press K1 key, the 6th, lower and sixth digits will flash, adjust the upper limit one digit, press K2, K3 to adjust 0-9 changes
Press the K1 key for the 7th time, the digital tube is not flashing, it displays the measured current value
