Description

The TU846 3BSE022460R1 is a module termination unit (MTU) for redundant configuration of the field communication interface CI840/CI840A and redundant I/O. The MTU is a passive unit having connections for power supply, two electrical ModuleBuses, two CI840/CI840A and two rotary switches for station address (0 to 99) settings.

A ModuleBus Optical Port TB842 can be connected to TU846 via TB846. Four mechanical keys, two for each position, are used to configured the MTU for the right types of modules. Each key has six positions, which gives a total number of 36 different configurations.

Module Termination Unit for dual CI840/CI840A, redundant I/O. TU846 are used with redundant I/O modules and TU847 with single I/O modules. The maximum ModuleBus length from the TU846 to the ModuleBus terminator is 2.5 meters. TU846/TU847 needs space to the left in order to be removed. Cannot be replaced with power applied.

FAQ

Q: Can the TU846 3BSE022460R1 be replaced while running like the TU845?
A: No. The TU846 3BSE022460R1 does not support hot-swapping and must be installed or replaced while the power is off.

Q: How many CI840 modules can be installed in one TU846 3BSE022460R1?
A: It is designed for redundancy and can accommodate 2 CI840/CI840A modules.

Q: Are there any special space requirements for installing the TU846 3BSE022460R1?
A: Yes. Due to its structural design, the TU846 3BSE022460R1 requires sufficient space on the left side to be easily removed from the rails during disassembly.

Q: Does the TU846 3BSE022460R1 come with a ModuleBus terminating resistor?
A: The standard package typically includes two TB807 module bus terminating resistors to complete the physical closed loop of the communication bus.

Q: Why can't I insert my CI840 module into the TU846 3BSE022460R1?
A: Please check the positions of the four mechanical keys on the TU846 3BSE022460R1. They must be set to the encoding that matches the target module; otherwise, the error-proofing mechanism will prevent insertion.
