Wiring
①Connect 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.
②Make connections to the DO contacts.
③Connect 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.
