NEW Allen Bradley 1747-L542 /D SLC 500 SLC 5/04 Processor DH+/RS232

About 1747-L542:

The AB 1747-L542 is an SLC 500 SLC 5/04 modular processing unit that has the capacity to handle 32K words, specifically 4K words just for storing data and 28K words for storing data and programs. It has an absolute maximum of 4096 discrete inputs and 4096 discrete outputs, with 480 maximum local analog I/O. The 1747-L542 also has a maximum of 3 local I/O chassis, with a maximum of 30 slots in the local I/O chassis. Its I/O scan time is 0.255 milliseconds, typical program scan time is 0.9 milliseconds/Kword, and bit execution time is 0.37 milliseconds, with a program scan holdup time of 20 milliseconds to 3 seconds after a power loss.

The power scan hold-up time depends on the loading of the power supply. It also uses a Flash EPROM for its memory back-up and the 32KB RAM of the 1747-L542 processor is battery-backed. Communication ports present are an RS-232 port and a DH+ port. Status LEDs are also available, specifically for low battery, CPU fault, run, forced I/O, DH+, and RS-232. The 1747-L542’s backplane current is 1 Amp at 5 Volts DC and the current is 175 mA at 24 Volts DC. It operates at a temperature between 32 and 140 degrees Fahrenheit and it can be stored at a temperature between -40 and 185 degrees Fahrenheit, with an ambient relative humidity of 5 to 95%, non-condensing. This processor’s acceleration is 2.5G at 57 to 2000 Hertz, its displacement is 0.015 inches, peak-to-peak, at 5 to 57 Hertz, and its operating shock is 30G.
