1746-IO12

The 1746-IO12 is a digital I/O combination module with a combination of 120V AC inputs and relay contact outputs. Input operating voltage is 85...132V AC, and output operating voltage is 5...265V AC or 5...125V DC. 1746IO12 contains 6 inputs and 6 outputs. Input off-state current, max. of 2mA and continuous current per output of 1.5A at 120V AC or 1.2A at 24V DC. Backplane current load of 90mA at 5V DC or 70mA at 24V DC.

The strength and versatility of the Universal Remote I/O network comes from the breadth of products it supports. In addition to 1746 I/O, the Universal Remote I/O network supports many AB and third-party devices. Typical applications range from simple I/O links with controllers and I/O, to links with a wide variety of other types of devices. You connect devices through remote I/O adapter modules or built-in remote I/O adapters. Using the Universal RIO Network instead of direct-wiring a device over a long distance to a local I/O chassis reduces installation, start-up, and maintenance costs by placing the I/O closer to the sensors and actuators. SLC 5/03, 5/04, and 5/05 processors support pass-thru which lets you configure RIO devices remotely from an Ethernet, DH+, or DH-485/DF1 network, as well as block transfer instructions for faster reading and writing of I/O data.

Evaluate what communications need to occur. Knowing your communications requirements will help you determine which processor and which communications devices your application might require. An SLC processor communicates across the 1746 backplane to 1746 I/O modules in the same chassis in which the processor resides. Various models of SLC processors have various on-board ports for communication with other processors or computers. Also, separate modules are available to provide additional communication ports for communication with other processors, computers, and remotely located I/O. Each processor has one or two built-in ports for either EtherNet/IP, DH+, DH-485, or RS-232 (DF1, ASCII, or DH-485 protocol) communication. In addition to the on-board ports available with SLC processors, you have the option of providing another communication port for an SLC processor by adding a communication module. Adapter modules for 1746 I/O are available for ControlNet and Universal Remote I/O links. An I/O adapter module in a chassis with I/O modules interfaces the I/O modules with the I/O link for communication with a scanner port for a processor at another location
