Configuring the Power

Powering on the ioPAC Controller

The ioPAC controller can receive power from a 9 to

48 VDC power. Input power is

applied to the positive (

V1+, V2+) and negative (V1-, V2-) terminals on the

connector.

•

When the input voltage is below the minimum recommended voltage the ioPAC

will turn off.

•

The ioPAC has reverse protection and power input over-voltage protection,

allowing it to resist a maximum voltage of 60 V, and the ioPAC’s power input

over-current fuse protection specification is 5 A at 25°C.

After connecting the Moxa ioPAC controller to the power supply, it will take 30 to 60 seconds for the operating

system to boot up. The green Ready LED will not turn on until the operating system is ready.

ATTENTION

This product is intended to be supplied by a Listed Power Unit with output marked “LPS” and rated for

48 VDC

(minimum requirements). For railway rolling stock applications, these devices must be supplied by a galvanic

isolated power supply with design based on the EN 50155 standard.

Grounding the ioPAC

For most applications, it is desirable to ground the system by connecting the system’s power supply common

wire to the chassis or panel ground. The negative (–V) side of the DC power input terminal as well as all I/O

point terminals labeled GND are connected to chassis ground.

NOTE

Use 18 AWG wire for the power ground.

We highly recommend connecting the ground screw to the power terminal block’s ground.
