Description
The Allen-Bradley 1794-TB32 FLEX I/O Terminal Base Unit is a field wiring base that supports compatible 32-point FLEX I/O modules within the Rockwell Automation FLEX I/O platform. It provides electrical termination for field wiring while serving as the mechanical mounting base for the I/O module. The integrated FLEXBus connector links adjacent terminal bases to create the backplane used for power and communication throughout the I/O system.
The terminal base features 32 I/O connections, eight common terminals, and eight power terminals, with cage-clamp wiring designed for stranded copper conductors. Once installed on a standard DIN rail, field wiring remains connected to the base, allowing the I/O module above it to be replaced without disturbing external wiring. This arrangement helps reduce maintenance time and simplifies servicing of distributed I/O installations.

Electrical ratings include a maximum voltage of 31.2 V DC/AC at 50/60 Hz, total current capacity of 10 A, and individual I/O terminal rating of 2 A. The FLEXBUS internal bus is rated for 640 mA at 5 V DC. Isolation between field-wiring terminals and the FLEXBUS is 50 V continuous, with basic insulation tested at 2,121 V DC for 1 minute.
The 1794-TB32 is compatible with 32-point digital input/output modules such as the 1794-IB32, 1794-OB32, and the 1794-IB16D 16-point diagnostic input module. It is part of the broader FLEX I/O ecosystem that supports over 40 different analog, digital, and specialty modules.
- Packaging/Conveyor: Manages sensors, switches, and actuators for automated sorting and high-speed packaging
- Water/Wastewater: Supports telemetry panels with digital connections for flow, pressure, and valve monitoring
- Automotive: Deployed in robotics/assembly networks requiring organized, high-density wiring
- Process/Machine Control: Used for speed calculation, flow monitoring, and quantity counting in DCS

Install on DIN Rail: Slide the 1794-TB32 onto the DIN rail tight against the previous terminal base or adapter. Make sure the hook on the base slides under the edge of the adapter.
Connect Flexbus: Ensure the Flexbus connector is fully pushed to the left to connect to the neighboring module or adapter. Warning: Do not force the terminal base into the adjacent unit, as this can break the backplane communication hook.
Technical notes
The voltage rating for this module stands at 24 VDC, and it is compatible with applications operating at a voltage level of up to 31.2 VDC. The current handling capability is rated at 10A, ensuring adequate support for the devices connected to it. Designed to withstand a broad range of temperatures, the 1794-TB32 has a minimum operating threshold of -20°C and can function efficiently up to a maximum temperature of 70°C.
FAQs
-
What modules are compatible with the 1794-TB32?
+The 1794-TB32 is designed specifically for 32-point digital modules, such as the 1794-IB32 DC Input Module and 32-point output modules. -
What wire sizes can I use with the 1794-TB32?
+It accommodates stranded copper wire sized between 22 and 12 AWG (0.34 to 2.5 mm²) rated at 75 °C or higher, with maximum insulation of 3/64 in. (1.2 mm) -
What is the tightening torque for the screw terminals?
+Terminal screw torque should be between 0.56 and 0.79 Nm (5 to 7 lb-in). Periodically re-tighten screw connections to ensure optimal contact, as they can loosen over time due to vibration. -
Can I replace modules while the system is powered?
+Yes, the FLEX I/O platform supports Removal and Insertion Under Power (RIUP) without disturbing field wiring. However, doing this in a hazardous location can cause an electrical arc and risk explosion. Ensure the area is safe or power is removed first.
