4.9 Wiring Analog Input/Output Modules
(1) Definitions of the terminals
◆ 2-/3-wire (passive sensor): the sensor and the system share the same power circuit.
◆ 4-wire (active sensor): the sensor uses independent power supply and suggested not to share the
same power circuit with the system.
◆ Note: use cables with the same length (less than 200 m) and use terminal resistors of less than
100 ohm.

*1. Please use shielded cables to isolate the analog input signal cable from other power cables.
*2. If the module is connected to a current signal, the terminals Vn and
In+ (n=0~7) must be short-circuited.
*3. If the ripple in the input voltage results in the noise interference with the wiring, please connect the module
to the capacitor having a capacitance in the range of 0.1 μF to 0.47 μF with a working voltage of 25 V.
*4. Please connect the shielded cable to the terminal SG.
*5. Once AH04AD-5A is installed on a backplane, the terminal SG on AH04AD-5A and the terminal
on the
backplane will be short-circuited. Please connect the terminal on the backplane to the ground terminal
.
