The 1762-IF2OF2 MicroLogix analog I/O module by Allen-Bradley is an expansion I/O module that connects to MicroLogix 1200 programmable controllers and is built for industrial environments. The 1762-IF2OF2 has 2 differential unipolar inputs with a 2.5-millisecond update time and it uses a successive approximation analog/digital converter. The 1762-IF2OF2 has a common mode input voltage range of ±27 Volts, with 55 dB at 50 to 60 Hertz in common mode rejection. It has ±0.12% non-linearity, and overall accuracy of ±0.55% full at -20 to 65 degrees Celsius (-4 to 149 degrees Fahrenheit), and ±0.3% at 25 degrees Celsius (77 degrees Fahrenheit). It has an input impedance of 200 kOhms at the terminal voltage and 250 Ohms at the terminal current.
The 1762-IF2OF2 has an input voltage protection of ±30 Volts and an input current protection of ±32mA. The 1762-IF2OF2 has a maximum BUS draw current of 4 0mA at 5 Volts DC, and 105 mA at 24 Volts DC, with an analog operational voltage range between 0 and 10 Volts DC and 4 and 20 mA, which can reach a full-scale range of 0 to 10.5 Volts DC and 0 to 21 mA. It has a 12-bit unipolar resolution and repeatability of ±0.12%. The 1762-IF2OF2 has dimensions of 90 x 87 x 40 millimeters (3.54 x 3.43 x 1.58 inches) and it weighs approximately 240 grams (0.53 pounds). It has an operational temperature range between -20 and 65 degrees Celsius (-4 and 149 degrees Fahrenheit) and a storage temperature between -40 and 85 degrees Celsius (-40 and 185 degrees Fahrenheit) at 5 to 95% non-condensing relative humidity. The 1762-IF2OF2 is built to function at an altitude of 2000 meters (6561 feet) without derating and to withstand a maximum shock of 30G.
