ABB TU891 3BSC840157R1 Mounting Termination Unit

Product Description

The ABB TU891 3BSC840157R1 is a compact mounting termination unit designed for field signal and process power connections in industrial automation systems. It provides 8 channels through a terminal block connection, with 27 gray process terminals. Furthermore, its 24 V rating and maximum current of 2 A per I/O channel define its electrical connection capacity.

Product Features

• 8-channel configuration: Provides connection points for field signals and process power.
• Terminal block connection: Uses terminal blocks for field wiring connections.
• Compact design: Supports a compact mounting arrangement with horizontal orientation.
• Electrical capacity: Supports a maximum current of 2 A per I/O channel.
• Process terminals: Includes 27 gray terminals for process connections.

Technical Specifications

Electrical Connections

The TU891 provides terminal block connections for field signals and process power. Its 8-channel configuration supports the connection of field wiring, while the 27 gray process terminals provide the specified connection points.

Furthermore, the maximum current rating of 2 A per I/O channel defines the current capacity for individual channels. The 500 V AC dielectric test voltage specifies the insulation test condition rather than the normal operating voltage.

Frequently Asked Questions

Q: How many channels does the ABB TU891 have?

A: The TU891 has 8 channels for field signal and process power connections.

Q: What is the maximum current per I/O channel?

A: The maximum specified current is 2 A per I/O channel. Check the connected equipment and wiring requirements before selecting the termination unit.

Q: What is the difference between the 24 V rating and the 500 V AC dielectric test voltage?

A: The 24 V value is the specified voltage rating, whereas 500 V AC refers to the dielectric test voltage used to assess electrical insulation. They represent different electrical parameters.
