ABB TU844 3BSE021445R1 Redundant Module Termination Unit DCS Parts PLC Module

Product Details:

Description:

The TU844 MTU can have up to 8 I/O channels and 2+2 process voltage connections. Each channel has two I/O connections and one ZP connection. Input signals are connected via individual shunt sticks, TY801. The shunt stick is used to choose between voltage and current input. The maximum rated voltage is 50 V and maximum rated current is 2 A per channel.

The MTU distributes the two ModuleBuses, one to each I/O module and to the next MTU. It also generates the correct address to the I/O modules by shifting the outgoing position signals to the next MTU. The MTU can be mounted on a standard DIN rail. It has a mechanical latch that locks the MTU to the DIN rail. The TU844 serves as a communication interface, enabling the connection of various field devices to the control system. It supports a wide range of protocols and can manage both digital and analog signals. The unit is modular, allowing for easy expansion and configuration based on specific application needs. This flexibility is crucial for adapting to different operational requirements.

Four mechanical keys, two for each I/O module, are used to configure the MTU for different types of I/O modules. This is only a mechanical configuration and it does not affect the functionality of the MTU or the I/O module. Each key has six positions, which gives a total number of 36 different configurations. The unit typically includes a user-friendly interface for configuration and monitoring, allowing operators to easily manage settings and view system status.
