About 1747-L20G
The 1747-L20G Fixed Controller is a product of Allen-Bradley/Rockwell Automation and it belongs to the SLC 500 product line. It features 20 I/O points and a power supply as well as an instructional capacity of 1K (1,024) words in its memory. It is designed to operate at a frequency of 47 to 63 Hertz, and it has a line voltage rating of 24 Volts DC. The Allen-Bradley 1747-L20G Fixed Controller comes with sinking inputs rated at 24 Volts DC with a DC transistor source. This controller unit comes with an ON-state voltage rating of 10 to 30 volts DC as well as an off-state voltage rating ranging from 4 to 5 Volts DC. It has a nominal current rating of 20 milliamps at a voltage of 24 Volts DC for the input 0, with 8 milliamps at 24 Volts DC for the remaining inputs.
The Allen-Bradley 1747-L20G Fixed Controller module has an input turn-on time of 8 milliseconds at maximum with 8 milliseconds of turn-off time at maximum. The maximum off-state current rating of this fixed controller module is 1 milliamp. The Allen-Bradley 1747-L20G Fixed Controller features a high-speed counter module, and the counters have the ability to count at speeds of up to 8 kilohertz. The operators can use the input 0 as a high-speed counter input or as a normal input. The input features a selectable jumper filter so as to accommodate the dual function. The jumper must be cut properly for the high-speed counter usage, and shielded cables should be used to reduce the input noise. In addition, the power should be turned off before removing or adding a memory unit to prevent damage.
Allen-Bradley manufactures the 1747-L20G Controller as a fixed controller module and as part of the SLC 500 series. It has a power rating of 24 Volts DC, with 12 DC sinking inputs rated at 24 Volts DC and 8 DC transistor source outputs.
