Product details

Terminal Base for AC500 V2 Communication Expansion

The ABB TB521-ETH-XC (1SAP312100R0270) is the terminal base that slots into an AC500 V2 PLC system, providing two slots for communication modules plus onboard Ethernet and two RS232/RS485 serial interfaces. This is the layer that turns a CPU into a multi-protocol gateway without extra middleware. Rated for DC input voltage and IP20 protection, it fits inside a standard IP20 panel with an ambient operating range of -30 to +70 °C. Those temp numbers cover most production floors and even unheated enclosures, though the lower end could be tight for starting up a frozen line.

Integration into an AC500 V2 System

For AC500 V2. Provides two slots for communication modules, an Ethernet interface, and two RS232/RS485 serial interfaces. Power comes from the backplane DC input; no separate terminal power supply needed. The free slots give you flexibility to add PROFIBUS, CANopen, or a second serial protocol without changing the CPU personality.
