Wiring
The DN120 requires two connections – one to the DeviceNet network (male 5-pin micro
connector) and one to the target serial device (male DB9 connector). Follow all applicable
electrical codes in your area when mounting and wiring any electrical device.
All power is received from the DeviceNet network. The DN120 draws up to 50mA from the
24VDC power supply. Select your DeviceNet cables and power supply so that it can provide
sufficient current for all networked devices at their peak operating power.
