About 1747-L20N

The Allen-Bradley 1747-L20N is equipped with a power supply and a fixed number of I / O in one package. This module is a processor with an instruction capacity of 1,024 (1K). This module can operate at a frequency of 47-63 Hz. The Allen-Bradley 1747-L20N also comes with a high-speed counter. The counters are able to calculate at speeds up to 8 kHz. This module has the option of using input 0 as a normal input or as a high-speed counter. In this case, to accommodate this dual function, the input comes with a selectable jumper filter. Users must cut the jumper for high-speed counter usage. Shielded cables are recommended to reduce noise at the input. Machine motion during system checkout can be dangerous for personnel. During the checkout procedures, you must disconnect all devices which, when energized, can cause the engine to move.

The Allen-Bradley 1747-L20N has a Line Power of 24V DC. The 1747-L20N has an input of 24V DC Source Power. The output of this module is a DC Transistor Sink. This module's input has an On-state voltage of 10-30V DC. The Off-state voltage of this module's input is ranged from 4-5V DC. The nominal output current of this module's input is 20 mA at 24V DC (for input 0 only) and 8 mA at 24V DC (all others inputs). The turn-ON time of this module's input is 8 milliseconds (maximum). The turn-OFF time of this module's input is 8 milliseconds (maximum). This module's input has a Maximum Off-State Current of 1 mA.
