Features:
- This module can detect the current value in the circuit of AC 220V, control the on-off of the relay according to the limit current set by users.
- Settable the upper/lower limit of the current.
- Detection range is AC 0-5A with the accuracy of 0.01A.
- With error calibration function.
- Can turn off the LED display to reduce power consumption.
Specification:
Model: YF-17
Supply voltage: DC 5V/12V/24V (Optional)
Detection range: AC 0-5A (AC 220V)

Function description:
P-11: When the measured current > I1 (low limit current), the relay closed; When the measured current < I1, the relay opens;
P-12: When the measured current > I1, the relay closes; Maintain the state until the circuit board power off;
P-21: When the measured current > I2 (high limit current), the relay closes; When the measured current < I1, the relay opens;
P-22: When the measured current > I2, the relay closes; Maintain the state until the circuit board power off;
P-31: When measured < I1, the relay closes; When the current > I2, the relay opens;
P-32: When the measured current < I1, the relay closes; Maintain the state until the circuit board power off;
P-41: When the measured current is between I1 and I2, the relay closes, opens in other cases;
P-42: When the measured current is between I1 and I2, the relay closes; Maintain the state until the circuit board power off;
P-51: When the measured current < I1 or > I2, the relay closes, opens in other cases;
P-52: When the measured current < I1 or > I2, the relay closes; Maintain the state until the circuit board power off.
Setting description:
Power on, display the measured current; (if the measured current terminal is none, the LED digits will pulse)
Press K1 for the second time (for over 1s to prevent misoperation)
, the screen shows: P11, k2 adjusts mode, K3 adjusts function
Press K1 for the second time, the screen flashes: 0.05, means the threshold I1 is 0.05A, K2 increases I1, K3 increases I1
Press K1 for the third time, the screen flashes: 0.10, means the threshold I2 is 0.1A; K2 increases I2, K3 increases I2
Press K1 for the fourth time, the screen shows the measured current, enters the standby state
Press K3 in standby mode for zero setting and error calibration
Press K4 in standby mode to turn on/off LED display
