Wiring Analog Input / Output Modules
Definitions of the terminals
◆
Two/three-wire (passive sensor): the sensor and the system share the same power circuit.
◆
Four-wire (active sensor): the sensor uses an independent power supply and should not 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. 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=1–4)
must be short-circuited.
