1734 POINT I/O

I/O Adapter and Communication Interface Modules

POINT I/O has three classes of communication interfaces.

An I/O adapter module provides an isolated DC/DC converter between field 24V DC and 5V backplane. You can connect up to 13 I/O modules and an I/O adapter with a maximum of 10 A field power. Additional I/O modules require the use of one or more POINT I/O 24V DC expansion power units. An I/O adapter supports up to a maximum of 63 I/O modules. The I/O adapter modules are available for ControlNet, DeviceNet (with and without subnet connectivity), EtherNet/IP, or PROFIBUS DP networks.

The DeviceNet Communication Interface module interfaces I/O modules to the DeviceNet link and converts field 24V DC power to 5V DC backplane power. The backplane power is derived from the DeviceNet network and is not isolated. I/O circuits require a power supply specified for the I/O module connected to the right of the communication interface module. You can connect up to 13 I/O modules to the DeviceNet Communication Interface module, with a maximum of 10 A field power.

A DeviceNet Communication Interface module with integrated I/O is also available (1734D POINTBlock). POINTBlock modules offer up to 16 integrated I/O circuits. A POINTBlock module interfaces the integrated I/O circuits and attached I/O modules to the DeviceNet link, and converts 24V DC DeviceNet power to 5V DC. The backplane power is derived from the DeviceNet network and is not isolated. I/O circuits require a power supply specified for the built-in I/O. You can connect up to 13 I/O modules to each POINTBlock module with a maximum of 350 mA field power.
