The PLC 1734-ACNR I/O adapter provides an interface for communicating with and controlling I/O modules from a ControlNet network. This adapter offers several control solutions including high-speed data transfers between I/O devices and controllers. The 1734-ACNR handles redundant media and it supports local communication via the network access port.
With just one 1734-ACNR ControlNet Adapter, multiple I/O control connections can be established. For digital modules, up to 5 rack-optimized, I/O connections can be made per adapter. It also allows up to 25 direct connections for specialty and analog modules. The total number of supported connections in the network depends on the I/O configuration. The I/O capacity can be further expanded to as many as 63 I/O modules using multiple 1734-EP24DC power supplies. It is important to note that the 1734-ACNR can only control I/O modules from Series C or later. The adapter uses a standard 24 Volts DC power supply with 10.2W of maximum power. It has a maximum backplane current of 1 Amps at 5 Volts DC.
