Rockwell Automation 22-XCOMM-DC-BASE DSI External Communications Kit - Manual (Page 4)

The 20-XCOMM-AC-PS1 is an accessory AC-to-DC
converter for use with the External Comms Kits. It is used
when only 100…240V AC power is available inside a
control panel. The converter, which comes with
interchangeable plugs, is shown below. The converter
connects to an AC receptacle inside the control panel. Use
the appropriate plug for your region:

Powering a Single Comms Kit
The DC output plug is connected to the mating DC ADP
connector on the 22-XCOMM-DC-BASE.
Powering Daisy-Chained Comms Kits
Additional Comms Kits can be powered by daisy-chaining
them together. For each Comms Kit in the chain, connect all
DC “+” terminals together and all DC “-” terminals together
(
Figure 5 ).
Figure 5 Powering Multiple Comms Kits via Daisy Chaining
The number of Comms Kits that can be daisy-chained
together is dependent on:
• Total current consumed by all of the communication
adapters being daisy-chained. For adapter current
consumptions at 24V DC, see
DC Power Supply
Requirement on page 3 .
• Available current output capacity of the AC-to-DC
converter being used.
The following example explains how to determine the
number of daisy-chained Comms Kits that can be powered:
Example: Suppose the Comms Kits being daisy-chained
each have an installed 22-COMM-D DeviceNet adapter, and
that the kits will be powered by the 20-XCOMM-AC-PS1
converter which has an output capacity of 830 mA.
Since the current consumed by one Comms Kit is 60 mA,
divide the power source’s available output capacity by this
consumption (830 mA ÷
60 mA = 13.83), and round down
the result. For this example, up to 13 daisy-chained Comms
Kits can be powered.
