ABB | TU846|Terminal Unit
Description
TU846 is a terminal unit designed for use with ABB's Freelance series controllers, specifically tailored for applications requiring 24 V DC process voltage. It supports the installation of I/O expansion modules and ensures secure mechanical locking when properly seated. The terminal unit facilitates easy removal and replacement of I/O modules without disturbing the wiring.
Features
- Supports 24 V DC process voltage.
- Secure mechanical locks for I/O modules.
- Enables hot-swapping of I/O modules.
- Direct connection to an earthed DIN rail or via screws for wall mounting.
Technical Specifications
- Terminals: 32 in total, distributed into 4 groups of 8 channels each (1.0...1.7, 2.0...2.7, 3.0...3.7, 4.0...4.7).
-
Process Voltage:
- Terminals 1.8 to 4.8: +24 V DC (UP)
- Terminals 1.9 to 4.9: 0 V (ZP)
- Max Permitted Total Current: 10 A between terminals 1.8...4.8 and 1.9...4.9.
- Supply Voltage: 24 V DC from the I/O expansion bus, FieldBusPlug, or CPU.
-
Conductor Cross Section:
- Solid: 0.08 mm² to 2.5 mm² (28 AWG to 13 AWG)
- Flexible: 0.08 mm² to 2.5 mm² (28 AWG to 13 AWG)
- With wire-end ferrule: 0.25 mm² to 1.5 mm² (23 AWG to 15 AWG)
-
Stripped Conductor Length:
