Description
1.Product Brief Introduction
This part is ABB original terminal base unit for S500 series I/O modules, matching AC500 and AC500-eCo PLC system, manufactured complying with IEC industrial standards and ABB global production specifications. It is DIN rail mounted fixed base used for clamping and mechanical positioning of S500 I/O modules, realizing internal backplane bus interconnection between CPU rack and each expansion I/O module, optimizing cabinet wiring layout and improving equipment assembly standardization.
2.Model Definition Explanation
3BBSE is fixed prefix code of ABB automation base accessories for internal material coding management.042238 stands for inherent part serial number of this terminal base product inside factory catalog.R2 denotes second revision upgraded version of structural and mechanical dimension compared with original base specification.
3.Technical Specifications
Rated applicable working voltage DC24V, insulation withstand voltage 250VAC. Working ambient temperature ranges from -25℃ to +60℃, storage temperature -40℃~+85℃, protection grade IP20 for cabinet internal installation. Made of flame retardant engineering plastic, compatible with full range of S500 DI,DO,DX,AI,AO series modules, passes IEC61000 EMC anti-interference and industrial vibration test.
4.Interface and Communication Configuration
Internal embedded backplane bus metal contact shrapnel to form bus channel after module clamping, data transmission completed via rack internal bus without extra field wiring. Bottom integrated buckle structure for fixed installation on standard 35mm DIN rail, no independent external communication port or fieldbus terminal reserved on base body.
5.Core Functions
Provide mechanical fixed support and positioning for S500 series I/O modules; realize reliable electrical docking of internal backplane bus between each module and system rack to ensure stable data communication between I/O modules and PLC CPU; unify installation benchmark of all expansion modules to reduce assembly deviation and loose contact risk.
6.Application Scenarios
Used in all AC500 series PLC automation control cabinets including packaging machinery, water treatment, conveyor production line, pump and fan control, environmental monitoring and light industry automated equipment control system, as essential installation carrier for S500 I/O expansion modules.
7.Operation and Maintenance Instructions
Check base plastic shell and internal bus shrapnel for deformation or damage before installation, fix base on DIN rail via bottom buckle. Insert corresponding I/O module vertically into base until mechanical locking is completed. Conduct maintenance every six months, clear accumulated dust inside bus contact area with dry soft brush, avoid liquid cleaning medium. Replace whole base when bus contact failure occurs after excluding module fault, unauthorized disassembly and modification of internal bus structure are forbidden.
