The Allen-Bradley 1747-L20L processor boasts an instruction capacity of 1K and is integrated with a power supply alongside a fixed number of I/O within a single compact unit. Equipped with capacitor-backed RAM, it operates efficiently within a temperature range of 0 to 60 °C and accommodates a wide relative humidity of 5% to 95% without condensation. With a typical scan time of 8 milliseconds for 1K and a bit execution time of 4 milliseconds, this module is built for performance, requiring a maximum power of 50 VA and a 40 A inrush current. The module effectively utilizes its enclosure for heat dissipation while allowing additional cooling solutions if significant external heat sources are present.Technical specifications for 1747-L20L Manufacturer Rockwell Automation Brand Allen-Bradley Part Number/Catalog No. 1747-L20L Series SLC 500 Module Type Fixed Controller Inputs (12) 24 V DC Source Outputs 8 DC Transistor Sink Line Power 120-240 Volts AC High-Speed Counter Yes User Power 24 Volts - 200 milliamps Cable Belden 9463 Connectors 6-Pin Phoenix Connector Weight 0.37 pounds (168 grams) Dimensions 5.72 x 1.37 x 5.15 inches Operating Temperature 0-60 Celsius
