load cell transmitter communication RS485 RS232 4-20mA 0-10V relay out 6 digit display
220 Weight Indicator
Specifications:
1. Analog input
Analog inputs use 20 bits AD chip, Count Speed up to 80 times / sec, the measurement accuracy of 0.2%
Display range -9999 ~ 19999
The largest sub-degree 50000
For the bridge voltage 5V, 100mA
2. The switch output
3 relay or OC outputs. Relay contacts AC 250V / 1A, OC output drive 100mA / 48V optional.
3. Transmission output
Output 4-20mA, 0-10V, 12bit precision driving 500 ohm load. Optional features.
4. communication port
485,232 communication interface, upload executable modbusRTU and active protocol. This function is optional. Only can choose one function with transmission function
5. A simple comparison output
Features: 3 output meter can be set to be greater than or less than the comparative comparison. When the measured value exceeds the upper limit output is active when the measured value is less than the upper limit minus hysteresis output is invalid. If the output is less than comparison, the measured value is less than the lower limit of the output is active when the measured value is greater than the lower limit plus hysteresis invalid.
3.1 parameter modification. Standby mode, press [k1] + password to enter the password written 100. Entering advanced parameters (13 parameters later) password is written 105.
Specific steps are as follows: Press [k1] key, there will be 00000, after press [k4] key to move the blinking digit moves to the flashing digit to be modified, press [k3] to modify the blinking digits, password changes is correct, press [k1] key to enter the set parameters, and then press [k1] to switch the set of parameters, select the parameter to be modified, press [k4] enter the parameters after the modification is completed, press [k1] OK to return to the measurement interface [k2]
3.2 weight calibration. Standby mode, press [k2], to see details of the third page (V: calibration method)
3.3 Key cleared. Standby mode, press [k4], and the measured value is less than zero range is completed is cleared.
3.4 restore the factory settings. 3.1 according to enter parameter modification (but need to enter a password to use special password) to switch to the first 42 parameters, enter a number between 11-19, and then press the [k1] to switch to the next parameter, press [k2 [to exit the way to restore the instrument parameters 1-9 initial state.
