Chapter 2 Analog Input Module AH04AD/AH08AD External wiring (1) AH04AD-5A/AH08AD-5A +24V 0V +24V 0V *1. Please use a shielded cable as an analog input cable, and isolate the shielded cable from other power cables. *2. If current is connected, the connection between Vn+ and In+ needs to be a short circuit. (n is in the range of 0 to 7.) *3. If ripple voltage results in interference with the wiring, please connect a 0.1~0.47 μF and 25 V capacitor. *4. Please connect the ground in the shielded cable to the terminal SG. *5.
Once AH04AD-5A/AH08AD-5A is installed on a backplane, the connection between the terminal SG on AH04AD-5A/AH08AD-5A and the terminal on the backplane will be a short circuit. Please connect the terminal on the backplane to the ground terminal . 2-17 Four-wire connection: Voltage input AG -10V~+10V Shielded cable*1 CH0 1M + V0+ +24V 250 - *3 I0+ 0V 1M VI0- *4 SG AG Four-wire connection: Current input CH1 -20mA~+20mA Shielded cable*1 1M V1+ + *2 250 +24V I1+ - 1M 0V VI1- *4 SG wo-wire connection: Current input 4mA~+20mA AG +24V Shielded cable*1 CH2 + 1M V2+ - *2 250 I2+ 1M 0V VI2- *4 SG ee-wire connection:
