ABB 1SAP114100R0170 - TB541-ETH CPU Terminal Base

The ABB 1SAP114100R0170 is the order code for the TB541-ETH CPU terminal base, a four-slot module carrier with an Ethernet interface for the ABB AC500 PLC family. ABB conformity documentation lists the code as TB541-ETH: AC500 module carrier with four slots, and distributor listings describe it as a CPU terminal baseboard for AC500 with Ethernet connectivity, offered new and used with warranty. Compared with the two-slot TB521 and one-slot TB511 bases, the TB541 provides the most module slots for larger AC500 configurations. Terminal style and revision should be confirmed with the supplier before ordering.
