Rockwell Automation 1203-EN1 EtherNet/IP-to-SCANport Module - Manual (Page 24)

2-6 Installing the Module
The 1203-EN1 module requires DC power from either an appropriate
DC power source or an AC-to-DC converter. Connectors for both are
provided.
Important: In either case, the DC power source or AC-to-DC converter
that you use must be capable of providing 150 mA @ 18-27
VDC .
Using 24 VDC Power Terminal Block
1. Connect the “+” and “-” wires of your DC power source to the 2-pin
linear plug (provided with the 1203-EN1 module), matching the
respective polarity.
2. Insert the 2-pin linear plug into the mating 24 VDC power terminal
block ( Figure 2.1 ).
Using AC-to-DC Converter Connector
Plug the AC-to-DC converter such as an Allen-Bradley
20-XCOMM-AC-PS1 AC Power Adapter into the mating DC ADP
receptacle (
Figure 2.1 ).
Powering Daisy-Chained 1203-EN1 Modules
You can power additional modules by daisy-chaining them together. For
each module in the chain, connect all DC “+” terminals together and all
DC “-” terminals together (
Figure 2.5 ). We highly recommend using
twisted wire pairs for better noise immunity.
Applying Power
!
ATTENTION: Risk of equipment damage, injury, or death exists.
Unpredictable operation may occur if you fail to verify that parameter
settings are compatible with your application. Verify that settings are
compatible with your application before applying power to the drive.
