Ex1n4TC Wiring
Note :
1) To avoid effects of noise to make result is not accurate, please use cable with isolation and should be far away
high-voltage power supply.
2) To avoid electric shock or damage of product, turn off all power supply when performing wiring work.
Remark:
*1 Use a two-core, twisted, shielded cable for the analog input line, and separate it from other power lines or a lines
easily induced.
*2 If there is voltage ripple in the input or there is noise in the external wiring, connect a capacitor of approximately
0.1 to 0.47
μ
F, 25 V.
*3 For the current input, make sure to short-circuit the “VN+” terminal and the “IN+” terminal (N: input channel No.).
*4 Make sure to connect the terminal to the terminal of the PLC main unit to which Class D grounding (100
Ω
or less) is performed.
