Description
2500 Series® PLC System
Product Bulletin
The 2500 Series® bases provide four, eight, eleven,
or sixteen slots for I/O modules in the CTI 2500
Series® or SIMATIC® 505 platform. The 2500-R11-A
allows two power supplies and two RBCs in a
redundant configuration. All other bases provide
space for a single power supply, and a CPU or RBC,
and can be mounted from the front or rear. New
2500P bases include the new CTI high-speed
communications channel for future installation of
Advanced Function Modules.
Features
• Replaces Siemens® 505-6504. 505-6508. 505
6511. or 505-6516
• Four, eight, eleven or sixteen I/O slots
• Mounts from the front or rear
• 2500-R11-A allows use of two power supplies
and two RBCs in a redundant configuration
• High-speed lower backplane for communication
with Advanced Function Modules (2500P bases
only)
• Embedded client/server protocols perform data
transfer based on configuration tables without
the need for any additional logic in the PLC or
2500P-ACP1 application program.
Power Supply, CPU/RBC, and I/O Location in Base
The power supply must always be installed in the left most slot of the base. To the right of the power sup
ply is a slot for a CPU or RBC. The remaining 4. 8 (shown below) or 16 slots are for I/O or communication
modules. When using a 2500-R11-A, power supplies are located in the left-most two slots. RBCs are
located in the next two slots, followed by up to 11 I/O modules.
Installing the Mounting Base
1. Use the following steps for installing the mounting base.
2. Determine if the base will be mounted with front or rear mounts.
3. Locate the mounting ears in the appropriate front or rear locations with supplied hardware.
4. Mount the base with screws in four ‘ear’ slots (screw hardware not included).
5. Include sufficient distance from other heat sources to maximize convection airflow cooling.
6. Follow manufacturer’s instructions for proper installation and removal of CPU,RBC, and I/O modules.
7. The 2500 Series Bases should be installed in a secured cabinet accessible by using a key or tool.
The cabinet must be suitable for the installation environment.
8. Blank slots not containing a module should be covered by a blank filler panel CTI part #2500-SB.
9. This equipment is suitable for use in Class I, Division 2. Groups A, B, C, D or non-Hazardous Loca
tions only.
