Additional Information

The TU842 MTU can accommodate up to 16 I/O channels and 2+2 process voltage connections. Each channel has two I/O connections and one ZP connection. The maximum rated voltage is 50 V, and the maximum rated current is 3 A per channel.

The MTU serves to distribute the two ModuleBuses to each I/O module and to the next MTU. It also generates the correct address for the I/O modules by shifting the outgoing position signals to the next MTU.

The MTU can be easily mounted on a standard DIN rail and features a mechanical latch that securely locks it in place. Four mechanical keys, two for each I/O module, are used to configure the MTU for different types of I/O modules, offering a total of 36 different configurations.

Features and Benefits

• Complete installation of I/O modules using 3-wire connections and field power distribution.
• Supports up to 16 channels of field signals and process power connections.
• Provides connections to two ModuleBuses and I/O modules.
• Mechanical keying prevents the insertion of the wrong I/O module.
• Secure latching device for DIN rail grounding.
• DIN rail mounting for easy installation.

This TU842 MTU is designed to facilitate the efficient and reliable installation of I/O modules in various industrial applications.
