Allen Bradley 1747-L532 SLC 5/03 processor is manufactured as part of the SLC 500 product line. This module is small, simple, and pocket-sized thus portable, with a variety of applications including HVAC control, material handling, and small process control. It features a program scan time of one millisecond per keyword. Allen Bradley 1747-L532 PLC controller has a backplane current of 175 milliamps at 24 volts DC and 500 milliamps at 5 volts DC. It has an all-out of 2 local input and output chassis with a maximum of 30 module input and output slots in the local I/O chassis. It uses RS-232 and DH-485 ports for communication, and these can be configured for connection to a 1761-NET-AIC converter. It features a standard battery-backed RAM as well as Flash backup memory. The 1747-L532 comes with a PLC-5 processor-based advanced set of instruction. It can either be a stand-alone or distributed through a system for SCADA applications. It has a total user memory of 16 keywords with 12 keywords for data and program, as well as 4 keywords for data only. The processor features up to 4096 outputs, 4096 inputs, and 480 local analog inputs and outputs. This processor allows for the DeviceNet scanner module and remote I/O scanner module to be installed to configure the input and output through a DeviceNet network or a universal remote link. The 1747-L532 SLC processor offers 0.44 milliseconds bit-instruction execution time and 10 times the overall system compared to its competitors.

The Allen Bradley 1747-L532 SLC 5/03 processor has a program memory consisting of 16 K words. In terms of memory back-up options, the Allen Bradley 1747-L532 has Flash EPROM. This product is equipped with several status indicators. These indicators include run, CPU fault, forced I/O, battery low, RS-232, and DH-485. The program scan hold-up time after this device loses power ranges from 20 milliseconds to 3 seconds. The clock and calendar accuracy of this Allen Bradley device is estimated to be plus or minus (+/-) 54 seconds per month at 25 degrees Celsius, or plus or minus (+/-) 81 seconds per month at 60 degrees Celsius. This Allen Bradley product has a maximum current rating of 0.500 amperes at 5 volts DC. At 24 volts DC, however, the maximum current rating of this device is 0.175 amperes. When the Allen Bradley 1747-L532 processor is being operated, the temperature of the surrounding area should range from 0 degrees Celsius to 60 degrees Celsius, or the equivalent temperature range of 32 degrees Fahrenheit to 140 degrees Fahrenheit. However, when this device is not being operated, or is being stored, the temperature of the surrounding area should range from -40 degrees Celsius to 85 degrees Celsius, or -40 degrees Fahrenheit to 185 degrees Fahrenheit. The humidity levels that are suitable for the operation of this Allen Bradley device range from five (5) percent to ninety-five (95) percent and be non-condensing. This product is capable of withstanding an operational shock rated up to 30 G.
