The Allen-Bradley 1762-L40BXB is a MicroLogix 1200 programmable controller. This module has 24 inputs and 16 outputs and weighs 2.4 pounds. The power supply is 100 to 240 Volts AC at 47 to 63 Hertz. The heat dissipation of this module is 21 Watts. The power supply usage is 80 VA. At 5 Volts DC, the power supply output will be 600 mA while at 24 Volts DC, the power supply output will be 500 mA. The input circuit type of the 1762–L40BXB is 120 Volts AC circuit and the output circuit is a relay type.
The 1762-L40BXB has two input specifications for 2 groups of inputs. The first group is for inputs 0 to 3 while the second group is for inputs 4 and beyond. For inputs 0 through 3, the on-state voltage is 14 to 24 Volts DC, the off-state voltage range is 0 to 5 Volts DC, and the operating frequency is 0 to 20 kHz. The normal impedance is 3.3 kΩ. For inputs 4 and above, the input specification as follows. The on-state voltage range is 10 to 24 Volts DC, the operating frequency is 0 to 1 kHertz, and the nominal impedance is 2.7 kOhms. Both inputs 0 through 3 and inputs 4 and above has the same off-state leakage current of 1.5 mA. The current per group of the 1762-L40BXB is 8 Amps. Do not exceed the “current per group common” specification to avoid damaging this module.
