ABB 125S2929-1 Module termination unit

Description

The module performs self-diagnostic cyclically. Module diagnostics include:

• External power supply, Transmitter power and External shunt error. Error in

these are reported as External channel error.

• Analog Read Back, Reference Voltage, Internal Power Supply, Checksum,

Watchdog and Memory. Error in these are reported as Module Error.

All the eight channels are isolated from the ModuleBus in one group. The power to

the input stages is converted from the 24 V supply on the ModuleBus.

The module has HART pass-through functionality. Only point-to-point

communication is supported.

Eight different types of MTUs can be used. The TU830/TU833 Extended MTU

enables three wire connection to the devices without additional terminals. The

TU810 (or TU814) Compact MTU has terminals for 24 V process voltage inputs,

but requires external terminals for distribution of 24 V power supply to the field

devices. The extended MTU, TU835, and TU838 provides a fuse (3 A max) per

channel for the outgoing transmitter supply. TU818 Compact MTU provides

connection to 2-wire transmitters without external marshaling. The TU812 Compact

MTU has a D-Sub 25 pin (male) connector for connection to the process.

Shielded field cables for process connections are required, if HART is used.

The parameter Shunt mode should be set to Internal shunt when current input is

required and set to External shunt when voltage input is required.
