1xRS-485 optional interface, galv. isol. with power supply, autoidentification (instead of MR-0112 a MR-0113)
For the connection of superior systems, another PLCs, operator panels, frequency converters and further peripheral modules a number of communication submodules is at disposal. The serial interface of the central and communication module is realized in case of the TECOMAT TC700, TC650, Foxtrot a Tempo system by fitting the submodule in the corresponding position on the module. In case the channel is not used, the position can remain free. MR-0114 - RS-485 interface with galvanic isolation
- submodule with own power supply source and identification
The MR-0114 submodule is used for the transmission of the TTL signals of the serial interface to the RS-485 interface with galvanic isolation. This interface works in the semi-duplex mode and allows multidrop interconnection of participants. For proper functioning, the communication line has to be terminated correctly (see the following paragraphs). The galvanic isolation of the serial interface is ensured by a builtin converter and no external power supply is required. Detailed information on the submodule, its internal connection and setup are described in the documentation TXV 101 04.
