The Allen-Bradley 1760-L12BWB-ND Pico Expansion I/O Controller is a programmable electronic relay controller with a built-in Logic module, timer module, and internal real-time clock which is used to perform a wide range of tasks in both building and machine applications. It has 24 Volts DC line input voltage with an acceptable range of 20.4 Volts DC to 28.8 Volts DC, and it has a nominal input current of 80 mA at 24 Volts DC with a rated voltage dip of 10 milliseconds. It has eight 24 Volts DC digital inputs control (4 high-speed inputs), with an 8 to 28.8 Volts DC ON-state voltage range at 2.2mA ON-state Voltage, and with an OFF-state input voltage of 5 Volts DC. It also has a maximum signal delay time of 20 milliseconds for ON/OFF and OFF/ON, and it also has 2 to 60 10 Volts DC Analog inputs with 11.2KΩ input resistance and with a maximum signal delay time of 20 milliseconds ON/OFF.

The 1760-L12BWB-ND has 4 programmable relay outputs with a 2-Hertz resistive load amp and a 0.2-Hertz inductive load amp, and it has 6KV rated impulse voltage with 250 Volts insulation voltage using reinforced insulation. It has terminals made of AWG 22 to AWG 12 solid or stranded wires with 5 to 7 pounds on an inch of tightening torque, and it is installed via a DIN Rail mounting or a Screw mounting option. It has a wide operating temperature range of -13 to 131 degrees Fahrenheit without de-rating, and it has a storage range of -40 to 158 degrees Fahrenheit at 5% to 95% non-condensing relative humidity. It has an IP20 rated protective enclosure and is designed to withstand a 15G operating shock with 2G vibration at 57 to 150 Hertz operating range. The 1760-L12BWB-ND weighs approximately 200 grams, and it has a net dimension of 71.5 x 90.0 x 56.5 millimeters.
