Connect the external power supply to the removable terminal block (RTB) to provide MOD
power and SA power. The adapters use different RTBs to connect power.
PointMax EtherNet/IP adapters use one 6-terminal power RTB.
PointMax EtherNet/IP Adapter Power Connection
For more information on how to connect MOD power, see the PointMax I/O System
Installation Instructions, publication 5034-IN001.
Module Power (MP)
MP power is required in a PointMax I/O system.
PointMax EtherNet/IP adapters provide power to a PointMax I/O system via an adapter
RTB that is connected to an external power supply and installed on the adapter. The
adapter RTB provides module power (MP+/-) to the system. Module power refers to
system-side power that is used to operate the PointMax I/O system.
You must limit the MP power source to 18...30V DC. The rated current
should be at least 850 mA (maximum limit of 10 A). The inrush current
handling capability should be at least 6 A for 10 ms.
For more information, see Switched Mode Power Supply Specifications
Technical Data, publication 1606-TD002.
You must use SELV-listed or PELV-listed power supplies for MP power.
Sensor Actuator (SA) Power
SA power is field-side power that is connected to the adapter, 5034-MBSA mounting
base, or 5034-EXP module. It powers devices that are connected to the I/O
modules.
You must limit the SA Power source to 10 A, max, at 18...30V DC.
For more information, see Switched Mode Power Supply Specifications
Technical Data, publication 1606-TD002.
You must use SELV-listed or PELV-listed power supplies for SA power.
You must connect SA power for safety I/O modules to provide the required
safety function.
Backplane Power (BP)
The backplane power is generated from module power by the adapter and expansion
power. It internally powers the I/O modules in the system. The adapter can supply
power to a maximum of 16 I/O modules. To extend support for an additional 16
modules, use a 5034-EXP or 5034-EXPXT expansion power.
