Delta AS218TX-A

4.9 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.
