Wiring

① Connect the external power to Accura 2350-DO module. Connections to the external power supply

should be made according to the positive/negative polarity of ports. The device can also operate with

the internal power supplied via the RJ12 6C communication line when it is not connected to the

external power supply. In this case, when digital output contacts operate, a voltage drop may occur

due to increased current consumption when current flows through the RJ12 6C communication line.

It can reduce the power supply voltage. Thus, when the contacts of all DO channels of the DO module

are closed[with the greatest current consumption], make sure to check if the power supply voltage

operates properly.

② Make connections to the DO contacts.

③ Connect the RJ12 6C communication line to the RJ12A/RJ12B port.

(Accura 2350-DO module receives power from Accura 2300[S] via the RJ12 6C communication line.)

1. When the external power supply is not connected to the Accura 2350-DO module, it operates with the internal

power supplied through the RJ12 6C communication line.

2. When the external power supply is not connected to the Accura 2350-DO module, make sure to check if the power

supply voltage operates properly considering a voltage drop may occur when the maximum current flows through the

RJ12 6C communication line. If there is any problem in the power supply, you should additionally connect the

external power supply to the module.
