About 1747-L20F
The 1747-L20F Fixed Controller is manufactured as a member of the Allen-Bradley SLC 500 product family. It is a basic type of fixed controller with a 1,024/1K-word processor capacity, 20 I/O points, and a power supply all packaged together as one unit. This unit features 12 input points rated at 24 Volts DC with 8 AC/DC relay output points. The I/O can be increased to a maximum of 64 I/O points through 2 I/O modules which are attached to the expansion chassis. The Allen-Bradley 1747-L20F Fixed Controller comes with a capacitor-backed RAM, and it provides optional memory backup options in the UVPROM and EEPROM modules. The module features a program memory capacity of 1K instructions with a typical scan time of 8 milliseconds per 1K instructions. The hold-up program scan time after a power loss is between 20 and 700 milliseconds with a line power of 120 to 240 Volts AC.
The Allen-Bradley 1747-L20F SLC 500 Fixed Controller module has an operating line power of 24 Volts DC, with an inrush power supply of 30 Amps at maximum and with 50 Volt-Amps of maximum power requirement. The rated user output power of this unit is 24 Volts DC and it has a current rating of 200 milliamps as well as power output voltage of 20.4 to 27.6 Volts DC. The 1747-L20F Fixed Controller by Allen-Bradley has a power fuse for protection that is rated for 1.25 Amps at 120/240 Volts AC and rated for 1.6 Amps at 24 Volts DC. Additionally, this controller supports the use of 14 AWG wire size and it supports a maximum electrical isolation rating of 1500 Volts for up to 60 seconds.
The Allen-Bradley 1747-L20F Fixed Controller is an SLC 500 Fixed Controller. This fixed controller has twelve 24 Volts DC sinking input points, and 8 AC/DC relay outputs with 24 Volts DC of line power.
