1. Wiring
1.1 connection analog sensor
1) Attach the corresponding wiring diagram provided randomly to the terminal. 2) The green, white and yellow temperature lines are connected to terminals 11,12 and 13 respectively. 3) Standard analog sensor (using CPK9 cable): the coaxial line and the black shielded line represent the measurement and reference signals respectively, connected to the "pH" and "REF" terminals respectively, and the brown equipotential line is connected to the "PA/PM" terminal.
4)ISFET analog sensor (using CPK12 cable): The core wire and black shielding wire of the coaxial line represent the measurement and reference signals respectively, and are connected to the "SRC" and "REF" terminals respectively, and the red wire is connected to the DRN terminal; Brown equipotential wire is connected to the "PA/PM" terminal. 5) The outer shield of the glass sensor cable is connected to the "S" terminal; the outer shield of the IsFET special sensor cable is connected to the PE terminal, and the PE terminal is grounded. 6) Marked "NC" and unmarked terminals are not connected. 7)220VAC power supply is connected to L1 and N terminals: 24VDC power supply is connected to and-terminals.
8) The first current output (pH) is connected to terminals 31 and 32, and the second current output (temperature, optional) is connected to terminals 33 and 34. Current output is active output
2.2 connection Memosens digital sensor
1) Attach the corresponding wiring diagram provided randomly to the terminal. 2) Brown, white, green and yellow cables are connected to terminals 87,8896 and 97 respectively
3) Marked "NC" and unmarked terminals are not connected. 4)220VAC power supply is connected to L1 and N terminals: 24VDC power supply is connected to and-terminals.
5) The first current output (pH) is connected to terminals 31 and 32, and the second current output (temperature, optional) is connected to terminals 33 and 34. Current output is active output
Note: Ensure that all cable plugs are tightened and sealed.
