The 1760-L18DWD-EX is an Allen-Bradley Pico Expansion IO Module series product. It is a Pico Controller of 1760 Bulletin group. This module has twelve (12) digital inputs and six (6) relay outputs. An input voltage of 12 Volts DC power supply is needed to operate this Pico Controller. There is an ample variety of variability options regarding the expansion techniques for this Allen-Bradley product. The controllers are equipped with both the Pico as well as the Pico GFX processors. For increasing and aiding the maximum user versatility, the 1760-L18DWD-EX has both AC and DC operating power versions. Special functions are performed by each of the devices ranging from the RTC (Real Time Clock), counters, and the logic features. The 1760-L18DWD-EX is both ways operational – through the display as well as through the keypad. The expansion modules can be directly connected to the Pico controller, and there is a large variety of options available. Electrical isolation is provided between the expansion module and the Pico Controller. If the primary isolation value that is 400 Volts AC is crossed, the controller and expansion units may get destroyed.
The range of the rated voltage may vary between 10.2 to 15.6 Volts DC. The residual ripple for the 1760-L18DWD-EX may be lesser than or equal to 5%. The display is LCD enabled, and there is no isolation between the inputs or to the power supply. The analog resolution for the 1760-L18DWD-EX is around 0.1V. The mechanical switching operations are approximately 10 million. Also, the Pico Controller can resist the resistive lamp load of 2Hz and inductive load of 0.5 Hertz.
