Integrator note — option board for AC500 system expansion
The ABB 3ABD00059607 is the TA5110-2DI2DOW option board, fitting into the AC500 PLC chassis to add two digital inputs and two digital outputs. Rated IP20, it requires enclosure mounting; no additional fieldbus interface is needed because the module communicates directly over the system backplane.
Mounting and environment — cabinet-only installation
The IP20 protection rating means the module must be installed inside a closed panel or cabinet, protected from dust and moisture. It clips directly into the AC500 backplane slot; no separate wiring is required for the backplane communication. Terminal connections for the I/O are accessible from the front for standard screw or spring-clamp wiring.
