YK-ACW105M AC Ammeter Digital Display Upper and Lower Limit Alarm Intelligent Current Controller Relay Detection

YK-ACW105M AC Ammeter Digital Display Upper and Lower Limit Alarm Intelligent Current Controller Relay Detection

Function:
- AC intelligent monitoring controller, used for measuring, displaying, and intelligent control of AC current in electrical circuits.
- Built in relay function, used for opening and closing under set conditions to achieve intelligent and automatic control.
- Built-in 485 (MODBUS) communication function, used for data exchange with PC, PLC, and various control devices to achieve online monitoring of current and device control.

Application:
- Current value monitoring
- Current overload protection
- Check if the monitoring equipment is working properly.
- Equipment linkage (such as linkage dryer, drum machine, water pump, exhaust fan, etc.).
- Control automatic feeding, stop feeding when the current is too high due to blockage, and resume feeding automatically after the conveyor belt returns to normal.
- After the device is shut down, continue to control the device or other devices to work for a period of time, or delay for a period of time before working for a period of time.
- Interact data with PLC, PC, microcontroller, etc. to achieve online monitoring.

Menu Description:
- F 01: AH upper limit alarm value/overcurrent alarm; 0: turn off upper limit alarm; > 0: If the display is greater than this value, it starts alarm (minimum can be set: lower limit + 2 * return difference).
- F 02: AL lower limit alarm value/under current alarm; 0: turn off the lower limit alarm; > 0: If the display is less than this value, it starts alarm (maximum setting: upper limit - 2 * return difference)
- F 03: D alarm return difference
  Example 1: Automatic control of feeder: AH is set to 180, D is set to 30. When the motor stalling current exceeds 180A, the alarm relay will disconnect. The alarm will end when the motor current returns to 150A (AH-D), and the relay will close.
  Example 2, Equipment work monitoring: AL set to 110, D set to 20, relay + sound and light alarm prompt when circuit current is less than 110A, end relay + sound and light alarm when current returns to 130A (AL+D).
- F 04: T1 start alarm delay value; delay before triggering (alarm triggered continuously for T1 seconds)
- F 05: T2 alarm release delay value; alarm hold (after triggering and disappearing, the alarm will hold for T2 seconds and end)
- F 06: L alarm lock; 0: Not locked, current returns to normal, alarm ends; 1: Locked, current returns to normal, still alarms until CLR is manually released.
- F 07: S calibration factor; 0.4 ~ 3.0, for internal reference only, please modify with caution.
- F 08: R range change; Set the range (i.e. maximum displayed current value) to 20 ~ 3000, the transformer is 100/5A, and set it to 100; It's 200/5A, set it to 200, and so on.
- F 09: B buzzer switch; 0: OFF; 1: ON.
- F 10: Modbus device address; 1 ~ 127, default 1.
- F 11: Baud rate; 0-5, corresponding to 4800, 9600, 19200, 38400, 57600, 115200

485-MODBUS Register Description:
- Real time current: 0-30000, units: 0.1A
- AH upper limit alarm value/overcurrent alarm: 0 or (lower limit + 2 * return difference) ~ 30000 units, 0.1A, default value 300
- AL lower limit alarm value/underflow alarm: 0 or 1 ~ upper limit - 2 * return difference, unit 0.1A, default value 0
- D alarm return difference: 0 ~ 9999 units: 0.1, default value 50
- T1 start alarm delay value: 0~9999 units: 0.1S, default value 30
- T2 release alarm delay value: 0-9999 units: 0.1S, default value 20
- L alarm lock: 0/1, default value 0
- S calibration factor: 40-300, for internal reference only, please be cautious when modifying. Default value 100
- R Range change: 5 ~ 3000, unit: 1A, default value 50
- B Buzzer switch: 0/1, default value 1
- Modbus device address: 1 ~ 127, default value 1
- Baud rate: 0 ~ 5, default value 1: 9600
- Interface: UART_485
- Data bit: 8bits
- Parity check: None Parity
- Stop bit: 1 Stop Bit
- Protocol: Modbus RTU (supports 0X03, 0X06 instructions)
- Note: If you forget the device address, you can modify it using the broadcast address. If the device address is changed to 1 (send command: 00 06 00 0A 0001 69 D9), the device will not return a message and the addresses of all devices on the bus will be changed to 1. Therefore, it is necessary to ensure that there are only devices on the communication line that need to be modified (after the address modification is successful, subsequent read and write operations need to use the new address).

Precaution:
- 220V danger, do not touch.
- Before powering on, please confirm if the wiring is correct (especially if the 220VAC wiring is connected incorrectly).
- Contact capacity 10A_250VAC 10A_30VDC, please do not exceed the limit for use.
- Only used for monitoring single current, multiple equipment lines cannot be threaded simultaneously, as it will affect measurement.

Package Included:
- 1 x Ammeter
