1. DESCRIPTION AND PARAMETERS
The long-distance transmission module CD-7252 is designated for transmission of
telemechanic data among PLC TECOMAT TC700 using fixed lines (for example long-distance
transmission cable). The module is of a slave type. The interface is optional in a form of sub-
module. There are available RS-232 (MR-0102), RS-485 (MR-0112), RS-422 (MR-0122)
interfaces which can be used for the connection with external modem. Then, the sub-modules
MR-0155 and MR-0156 are containing FSK modem (frequency shift keying) with frequency
modulation in the band of low-frequency signals corresponding to CCITT recommendation.

* This is a product of class A. In indoor conditions (i.e. such conditions, where using of radio
and TV sets can be supposed in a distance of 10 m from the mentioned equipment), the product
can cause radio disturbances. It might be required in such cases that the user takes necessary
measures to avoid this.
1.3 ELECTRICAL PARAMETERS
The parameters are dependant on installed sub-modules of communication interfaces and are
described in the documentation of the particular sub-modules.
