About 1747-L20L
The 1747-L20L Fixed Controller is manufactured by Allen-Bradley/Rockwell Automation as a member of the SLC 500 product line. This module is a processor that comes with a capacity of 1,024 (1K) instructions. It features a power supply as well as several I/O points in one device. This module comes with a capacitor-backed RAM, and it can tolerate 5 to 95 percent relative humidity with no condensation. This controller has an operating temperature range from 0 to 60 degrees Celsius, with a storage temperature range from -40 to 85 degrees Celsius. For most applications, convectional cooling is usually enough to help to keep the controller and its components within a specific operating temperature range.
The spacing requirements of the Allen-Bradley 1747-L20L Fixed Controller in the enclosure is sufficient for dissipation of heat in standard applications. In certain applications, there is a significant amount of heat generated by the equipment in and around the enclosure. In a situation like this, a blower fan should be placed in the enclosure to help with the circulation of air as well as with reducing the heat around the controller. In addition, a fan should also be used in environments with consistent high ambient temperatures. The 1747-L20L Fixed Controller features a typical scanning time of 8 milliseconds per 1K instructions. This fixed controller has a bit execution time of 4 milliseconds, with an inrush current rating of 40 Amps. It has a maximum power rating of 50 Volts-Amps and it supports the use of wire size of 14 AWG. The 1747-L20L Fixed Controller allows for the main power source breaker switch to be placed where the users or the maintenance persons can easily and quickly have access to it.
The Allen-Bradley 1747-L20L Fixed Controller is part of the SLC 500 series. It has twelve 24 Volts DC source input points, and 8 DC transistor sinking output points with 120 to 240 Volts AC of line power.
