About 1747-L20

The Allen-Bradley 1747-L20 is a module in the SLC 500 Fixed Hardware Style series. This module consists of a processor with an instruction capacity of 1,024 (1K). This module is equipped with a power supply and a fixed number of I / O in one package. The memory type of this module is a capacitor-backed RAM memory. This module can operate at a frequency of 47-63 Hz. The battery life of this module is 5 years. The Allen-Bradley 1747-L20 has a typical scan time of 8 miliseconds/1K. This module has a bit execution of 4 milliseconds. The power supply inrush rating of this module is 40 A. The maximum power requirement is 50 VA. This module has a wire size of 14 AWG. Sometimes the power source to the system can be temporarily disrupted. The voltage level may drop substantially below the normal line voltage range for a given period. Both of these conditions are considered as power loss for the system.

The relative humidity of this module is from 5-95% without condensation. The Allen-Bradley 1747-L20 has an operating temperature between 0 and 60 °C (32 and 140 °F). The storage temperature of this module is ranged from -40-85 °C (-40-185 °F). Do not carry this module into the unfiltered outside air. This may introduce harmful contaminants that may cause undue operation or component damage. In extreme cases, you may need to use an air conditioner to protect from heat buildup inside the enclosure.
