AC DrivesCustom Classic I/O Saver - AutoMate Rail to Allen-Bradley PLC Interface Module R7-20 Incorporate the features of an Allen-Bradley pro- grammable controller without installing new I/O The I/O Saver Rail Interface module lets you control field devices that are connected to a Reliance AutoMate® I/O with an Allen-Bradley programmable controller. The I/O Saver module resides as an adapter on the Allen-Bradley Remote I/O link. You can convert your Rail I/O system into an Allen-Bradley remote I/O link by simply replacing the AutoMate Remote I/O Heads with I/O Saver modules. There is no need to replace I/O modules and field wiring. Benefits • Easy-to-use I/O conversion process • Integration of Reliance Electric and • Allen-Bradley control systems • Significant cost savings over new • I/O systems Helps save I/O wiring costs and system start-up time Because the I/O Saver module is designed like a Remote I/O Head, you can replace existing Remote I/O Heads with the I/O Saver module. The I/O Saver has the same form factor as existing Remote I/O Heads and has four ports that can be used to connect to any of the following AutoMate I/O: • Digital Rails • Analog Rails • Local Head modules • LED modules • Thumbwheel switch modules By connecting four Local Head modules to the I/O Saver module, the I/O Saver module can control a maximum of 16 rails. Using AutoMate I/O already wired to existing field devices saves you the cost of buying, wiring, and troubleshooting a new I/O system. Integrates AutoMax™ DCS control systems with PLC control systems residing on your plant’s floor The I/O Saver module serves as a “bridge” between the Reliance Electric AutoMate Rail I/O system and the Allen-Bradley PLC control system, integrating the two product lines into one seamless control system. To a programmable controller, the I/O Saver module appears as up to 2 and 1/4 remote I/O racks that can be numbered from 0-37 (octal). As an I/O adapter, the I/O Saver reads the input data from the AutoMate Rail I/O and transfers this data to the programmable controller when scanned. When the I/O Saver module receives output data from the programmable controller, it passes this data to the AutoMate Rail I/O.

Notice that you can also connect the I/O Saver module to an AutoMax rack containing an AutoMax Allen-Bradley Remote I/O Scanner Module. Feature Summary On-board power supply - The I/O Saver module has its own power supply and provides connections to 120V or 240V AC input power. Ready Relay Contacts - A set of Ready Relay contacts installed in the I/O Saver module can be used as an additional E-stop circuit to remove power from the outputs in case of an emergency. The contacts close when the module is operating properly and open when a hardware problem or remote I/O fault or power loss is detected. Auto-detected remote communication rate - The I/O Saver module can communicate on the A-B Remote I/O link at 57.6, 115.2, or 230.4 kbps. When the module first powers up, it automatically detects and matches the communication rate being used by the programmable controller. Can communicate up to 17 words of data – When configuring the I/O Saver module, you must define whether you are connecting just Rail I/ O, just Local Head modules, or a mixture of both. The I/O Saver module allocates: • five words of data for just Rail I/O (one word for Rail status and four words for I/O data) • 17 words of data for Local Heads or a mixture of Rails and Local Heads (one word for rail status and 16 for I/O data) Status word for system monitoring - A status word lets you monitor the status of the Rail I/O. One bit is allocated for each rail, which you can use to detect whether a rail is present. LED indicators for troubleshooting - Use the six LED indicators to monitor and troubleshoot the module, communication, and remote I/O and Rail faults.
