Chapter 4 Analog Input/Output Module AH06XA 2. Pull up the clip. 3. The terminal block is removed. 4.3.3 Wiring Precautions In order to make the functions of AH06XA-5A perfect and ensure the reliability of a system at the same time, external wiring which prevents noise is necessary. Before installing cables, users need to follow the precautions below. (1) To prevent a surge and induction, an AC cable and input/output signal cables which are connected to AH06XA-5A must be separate cables. (2) A cable must not be installed near a main circuit, a high-voltage cable, or a cable connected to a load which is not a PLC.
Besides, a cable must not be bound to a main circuit, a high-voltage cable, or a cable connected to a load which is not a PLC. Otherwise, effects that noise, induction, and a surge have will increase. (3) Please connect a shielded cable and a hermetically sealed cable with the ground separately. (4) Terminals with insulation sleeves can not be arranged as a terminal block. It is recommended that the terminals be covered with insulation tubes. (5) Two-wire connection/Three-wire connection/Four-wire connection: Two-wire connection/Three-wire connection (Passive transducer): A transducer and an analog input module are connected to a power circuit collectively.
Four-wire connection (Active transducer): A transducer uses an independent power supply. It is not connected to the power circuit which is connected to an analog input module. 4-17
