1SAP112100R0160
Product ID
#145
The ABB 1SAP112100R0160 is the order code for the TB521-ARCNET terminal base, a two-slot module carrier with an ARCNET interface for the ABB AC500 PLC family. ABB's own conformity documentation lists the code with the description TB521-ARCNET: AC500 module carrier with two slots, and ABB release notes discuss CPU compatibility limits with this base - for example PM590-ARCNET operating on TB521-ARCNET with limitations. Distributors offer the base as new stock and also list it as a CPU module replacement for ARCNET-configured AC500 systems. Because ARCNET bases are being superseded by Ethernet variants, confirm CPU compatibility and stock status with the supplier before ordering.
