The Allen-Bradley 1760-L12DWD-ND is a Pico Controller from the 1760 series. This 12 I/O Pico controller is used for smaller and lower-cost applications. It comes equipped with 8 digital inputs (12 Volts DC) and 4 relay outputs. Two digital inputs (I7 and I8) terminals can also be used for analog input (0 to 10 Volts DC) processing. Its analog resolution is 0.1 Volts DC. Relay outputs have a 250 Volt AC operational voltage and are estimated to have 10 million switching operations. It is supplied with a 12 Volt DC power and comes with a real-time clock, although it does not contain a display or a keypad. There is one LED to signal the RUN statuses of the device and the inputs I1 to I4 can be used as an HSC (High-Speed Counter) with a counting frequency less than 1kHz.

This bulletin 1760 controller has acceptable functions for relays and time switching for most general applications; it can be applied to fans, lighting, window and door controllers, conveyors, and pumps. On the front face of the device is a socket for a memory module or a PC interface cable (beneath a protective cap). It is also used to make a backup copy which can be easily transferred to some other Pico controller or used when there is a need to replace a broken controller. The 1760-L12DWD-ND controller fits into an enclosure with dimensions of 71.5 millimeters (2.81 inches) x 90 millimeters (3.54 inches) x 58 millimeters (2.28 inches). The nominal input current of the controller is 140 mA at 12 Volts DC; the power dissipation is 2 Watts and there is no electrical isolation supplied between inputs and for power supply, only for outputs.
