•
Use a shielded cable or twisted pair.
•
Connect the shielded cable to the ground terminal inside the control box
•
Because current signals are relatively less sensitive to interference, use equipment that op
erates in current mode for the analog I/O terminals. You can change the terminals' mode
(voltage or current) in the software program.
The electrical specifications for the analog I/O terminals are as follows:

Voltage/Current Input
A voltage or current signal is received at a TBAIO terminal block between AIx terminal and GN
D terminal of TBAIO terminal block, from an external device. If the output of the opposite devic
e is voltage, 0~10Vdc of signal can be received. If the output of the opposite device is current,
4~20mA signal can be received.
※ The controller analogue input should be set as "voltage" or "current" at the teach pendant
according to the output signal (voltage/current) of the opposite device.
