TB5660-2ETH provides the highest communication-module capacity in the standard AC500 V3 TB56xx terminal-base family. It combines one processor position with six communication positions for controller stations that coordinate several industrial networks.

The expanded hardware arrangement requires a PM5670-2ETH or PM5675-2ETH processor at hardware index C0 or later; lower-capacity PM56xx processors are not listed for this base.

• Supports up to six compatible communication modules beside the processor module.
• Retains dual processor Ethernet, CAN, COM1 and local S500 I/O-bus connectivity.
• Provides a single mechanical platform for complex multi-network controller assemblies.
• Allows horizontal or vertical cabinet mounting with the applicable clearances and station limits.
• Maintains removable processor and communication modules while the field-wired base remains installed.

• Use only with PM5670-2ETH or PM5675-2ETH at hardware index C0 or later and confirm the processor label before assembly.
• Map all six slot positions, module order codes, networks and cable routes before panel construction or service replacement.
• A compatible AC500-S module can occupy a position, but only one AC500-S module may be installed on the terminal base.
• Check the total 24 V DC supply design and the current consumption of the complete installed station.

• Large AC500 V3 controller stations that bridge multiple plant and machine networks.
• Automation systems using high-performance PM5670 or PM5675 processors with extensive communication expansion.
• Panel designs that consolidate several fieldbus, Ethernet or serial communication modules.
• Lifecycle replacement where the wired base and exact slot population must be documented before shutdown.
• Standardized controller assemblies that require the maximum TB56xx communication capacity.
