The 1760-IA12XOW6I is a pico controller I/O expansion module manufactured by Allen-Bradley. It is rated at 100 to 240 Volts AC input voltage, 50 to 60 Hertz frequency, 5% tolerance, and it weighs 0.253 kilograms. It features 12 digital inputs, 6 isolated relay outputs, and an LED indicator to show the run or stop status as well as the status of the incoming power. The 1760-IA12XOW6I expansion module is designed to increase the I/O capacity of Bulletin 1760 Pico Controllers by increasing I/O points and it can be connected directly to a 1760 Pico controller regardless of whether or not the Pico controller and the 1760-IA12XOW6I expansion module are on different voltage types. The output relays of the 1760-IA12XOW6I expansion module are labeled S1 to S8, but only the relay outputs labeled S1 to S6 are available for I/O expansion purposes. The S7 and S8 outputs can be used as markers, and it is essential to note that it is not permissible to connect all outputs of the 1760-IA12XOW6I in order to increase output. In addition, the debounce setting does not affect the expansion module.

The 1760-IA12XOW6I expansion module's I/O data is transferred serially in both directions at a reaction time of 15 Milliseconds +1 cycle. Before mounting, the 1760-IA12XOW6I expansion module and the Bulletin 1760 Pico controller must first be connected together. Appropriately-rated Allen-Bradley surge suppressors, varistors, RC Network surge suppressors, and fuses can be integrated into the Pico Controller’s circuitry to protect the components. To prevent switching faults in machine systems, it is also important to always monitor the 1760-IA12XOW6I expansion module.
