AI Overview
The 1794-TB3S is a
Flex I/O Terminal Base Unit by Allen-Bradley, part of their industrial automation systems. The term "solar system module" in your query seems to be a misclassification; the device is for industrial process control, not solar energy applications. Key Features and Specifications
The 1794-TB3S unit is designed to mount on a DIN rail and provides the physical wiring terminals for Allen-Bradley Flex I/O modules.
- Product Type: Flex I/O Terminal Base Unit.
- Terminals: It has 16 I/O terminals, 18 common terminals, and 18 voltage terminals, utilizing a spring-clamp termination method for faster wiring.
- Voltage Rating: Supports a maximum supply voltage range of 125V AC/DC.
- Current Rating: Capable of handling a maximum of 10A.
- Wire Size: Compatible with 0.34-3.3mm² (22-12 AWG) solid or stranded copper wire.
- Isolation Voltage: Provides 125V continuous isolation voltage between the field wiring terminals and the FLEXBUS.
- Certifications: It is UL, CSA, CE, and Ex-certified for use in hazardous locations.
Function
This terminal base unit does not function as an independent "module" in the traditional sense, but rather acts as the foundation that a specific I/O module (e.g., an input or output module) plugs into, allowing it to connect to the industrial network and field devices.
For detailed technical documentation, you can refer to the Rockwell Automation literature library.
