Allen-Bradley 1794-TBN Flex Terminal Base

The Rockwell Allen-Bradley 1794-TBN Flex I/O Terminal Base Unit is a component used in industrial automation systems to connect various input/output (I/O) modules to a control system. It provides a physical interface for wiring and mounting these modules.

Key Features:

• 16 I/O Terminals: Accommodates up to 16 I/O terminals for connecting discrete or analog input and output modules.
• NEMA-Style Screw Clamps: Features NEMA-style screw clamps for secure connections of larger gauge wires.
• 2 Common Terminals and 2 +V Terminals: Provides common and positive voltage terminals for module power supply.
• DIN Rail Mounting: Designed for mounting on a DIN rail, a standard method in industrial control cabinets.
• 250V AC/DC, 10A Rating: Can handle a maximum voltage of 250 volts AC or DC and a current of 10 amperes.
• Voltage Isolation: Offers voltage isolation between the terminal base unit and the connected modules.
