Communications Power Supply
In a DeviceNet system, a 24-V DC communications power supply must be
supplied to the Network. The communications power supply must meet the
specifications listed in the following table and the AC inputs and DC outputs
must be isolated.
The OMRON S82J-series and S82K-series Power Supply Units are recom-
mended. Select a Power Supply Unit with a current capacity that can comfort-
ably handle the total power consumption of all connected nodes and allow for
future expansion if necessary.
Communications Power Supply Specifications
The communications power supply must meet the following specifications.
DRS3-1
Shielded Mini-size Connector with Terminating Resistance
(male plug)
DCN4-TM4
Used to connect the DCN4-TR4-1.
DCN4-TP4D
Flat Cable Power Supply Terminal Block with Terminating
Resistance
When flat cable is used, communications power can be sup-
plied from the terminals on this terminal block.
