The 1761-L20AWA-5A MicroLogix controller has a response time of 8 milliseconds for AC inputs for nominal filter setting as well as delay time of 20 milliseconds for ON and OFF. It also comes with a minimum power cycle of 50,000 with an isolation rating of 1500 volts AC.

The Allen Bradley 1761-L20AWA-5A MicroLogix 1000 programmable controller has a power supply voltage ranging from 85 volts alternating current (AC) to 264 volts alternating current (AC) at a frequency range of 47 hertz to 63 hertz. This device has a power supply usage rating of 20 volt-amperes at 120 volts alternating current (AC), as well as 27 volt-amperes at 240 volts alternating current (AC). Additionally, the maximum inrush current of this product's power supply is 30 amperes for 8 milliseconds. The recommended maximum terminal screw torque for this Allen Bradley product is 0.9 Newton-meters (N-m), or the equivalent of 8.0 pound-inches (lb-in.). This programmable controller can withstand an operating vibration with a peak-to-peak displacement of 0.381 millimeters at a frequency of 5 hertz to 2 kilohertz. Additionally, it can withstand a non-operating vibration with a peak-to-peak displacement of 0.762 millimeters at a frequency of 5 hertz to 2 kilohertz. The Allen Bradley 1761-L20AWA-5A can even withstand an operating shock rated at a 10 G peak acceleration for a duration of approximately 11 milliseconds, as well as a non-operating shock rated at a 20 G peak acceleration for a duration of approximately 11 milliseconds. Depending on the orientation this device is mounted, it should be operated at a temperature ranging from 0 to 55 degrees Celsius (horizontal mounting) or 0 to 45 degrees Celsius (vertical mounting). This programmable controller should be stored in an area with a temperature range of -40 to 85 degrees Celsius. The humidity levels suitable for this product's operation is 5 to 95 percent non-condensing.
