About 1747-L543:

The AB 1747-L543 is an SLC 500 SLC 5/04 processor that has maximum discrete input and output capacities of 4096 each. It has a maximum of 480local analog I/O, as well as a user memory of 64K words, specifically 60K words for data and program and 4K words for data only. It also comes with a Flash EPROM backup memory and 107 programming instructions. The 64 KB RAM of the 1747-L543 processor is battery-backed. The I/O chassis of the 1747-L543 is a maximum of 3, and it has a maximum of 30 I/O module slots. The communication ports present on this processor are a DH+ port and an RS-232 port. The 1747-L543 It also has status LEDs present for forced I/O, run, CPU fault, RS-232, and DH+.

Program scan time of the 1747-L543 processor is 0.9 milliseconds/K on average, its typical I/O scan time is 0.225 milliseconds, and bit execution is 0.37 µs. It also has a program scan hold-up time after the loss of power between 20 milliseconds and 3 seconds, which is also dependent on the loading of the power supply. The 1747-L543 also runs on backplane currents of 1 A at 5 Volts DC and of 125 mA at 24 Volts DC. Its operating shock is 30 G, and it can withstand an acceleration of 2.5 G at 57 to 2000 Hertz and a displacement of 0.015 inches, peak-to-peak, at 5 to 57 Hertz. Its non-condensing relative humidity is between 5 and 95%, its storage temperature is -40 to 85 degrees Celsius, and its operating temperature is 0 to 60 degrees Celsius.
