There are some models in the family of Omnii-Comm products. Other models are accessible for direct mounting in SLC 500 Programmable Logic Controllers and PLC 5 of |Allen-Bradley. A single module of slot for the PLC of Reliance Automate is also accessible. The units of stand alone for 19 inches rack mounting are presented for use in applications with other PLCs.

The single modules of slot PLC attach to the PLC back plane only for +5V power. All corresponding to the PLC acquires place more a standard serial port of communication, with the PLC native protocol. The stand alone units for example the rail of DIN mounted unit are accessible with either a 24VDC supply or a universal input AC supply. An option of 12VDC is also accessible.

The Omnii-Comm of 266-P00-XYZ is a stand alone rail of DIN mounted unit that can be utilized with some PLC or even with no a PLC in a lot of applications. The P in the part no is a number that states the serial ports number that the module is prepared with at the shipment time. You can arrange this module prepared with from serial ports of 3 to 5. The X in this part no chooses the requirements of input power. A 1 in this location chooses 100-240 VAC, a 2 chooses 24 VDC and a 3 12 VDC. The Y in the part nor is utilized to choose the connectors type for the serial ports P1 to P4. The Default of Configuration Connector, Connector P5, is always a 9-pin D.
