Specs & Technical Data
Specifications: 1747-L542 SLC 5/04 Processor, User Memory, Max: 32K words total (28K words for data or prog., 4K words for data only); Number of I/O: 4096 in + 4096 out absolute maximum; Local Analog I/O, Max: 480; Program Scan Time/Kword: 0.9 ms (typ); I/O Scan Time: 0.225 ms (typ); No. of Local I/O Chassis, Max: 3; No. of I/O Module Slots in the Local I/O Chassis, Max: 30; Communication Ports : DH+ & RS-232 (RS-232 port can also be configured for a DH-485 network); Backup Memory: Flash; Battery-backed RAM: Standard. 
Miscellaneous: Allen Bradley 1747-L542 SLC 5/04 processors manufactured prior to April 2002 draw 200 mA @ 24V dc. All new 1747-L542 controllers have 0 mA draw current @ 24V dc. The absolute maximum number of I/O for 1747-L542 processors only reflects the I/O addressing capability. It does not take into account the amount of memory that may be required for a ladder-logic program to monitor and control the I/O. The practical ratio of memory per I/O is totally dependant upon your specific application.
