The Allen-Bradley 1747-L542P processor is a Pro-Set 200 modular processor for SLC 5/04 systems. The 1747-L542P processor comes with a 32 kiloword program memory. The processor can support 8192 discrete digital I/O. Up to 3 chassis with a total of 30 slots for I/O can be used with the 1747-L542P processor. The on-board communication options include the RS-2343 and DH+ options. The memory backup option available for the processor is the flash EPROM. The status indicators provided on the processor for CPU fault, forced I/O, low-battery, RS-232, and DH+ status updates. The typical program scan time is 0.9 milliseconds.
The Allen-Bradley 1747-L542P processor requires 1 Amp of current at 5 Volts DC and 200 milliamps at 24 Volts DC. The accuracy of the on-board clock is ±54 seconds per month at 25 degrees Celsius which reduces to ±81 seconds per month at 60 degrees Celsius. The processor scan hold-up time after the power loss is 20 milliseconds to 3 seconds depending on the load of the power supply. The processor complies with the NEMA ICS2-230 standard for noise immunity. Environmental specifications for the 1747-L542P processor include a 0 to 60 degrees Celsius operating temperature range and a -40 to 85 degrees Celsius storage temperature range. The recommended range for non-condensing relative humidity is 5 to 95%. The processor must be installed in the slot 0 of the chassis. The protective wrap on the processor should be removed after installation to prevent overheating. The 1747-L542P processor should only be removed from the SLC 500 chassis when power is disconnected.

The highest amount of attachable I/O obtained by the SLC 500 series.
The very best when it comes to attachable analog on the SLC 500 series.
Not the most memory available, but coming in with 4 stars, the memory is still adequate for almost any operation
This unit's scan time is outrageously fast, ranking in as one of the fastest processors in the SLC 500 Series.
