"DP UkrGasTech" LTD - Transformers of interfaces

[prf_e.html] AN INTERFACES OF TRANSFORMERS Original appearance of transformers of interfaces : RS232/Bell202 ; RS232/RS485 ; RS232/RS232 is insulating ; RS232/ML ; The controller - converter of interfaces SH/RS232 PURPOSE 1. All let out the transformers of interfaces are intended for the transmission of signal in standard BELL202 on the dedicaded twowire line in the poludupleksnom mode and author of power supply tension for peripheral units; for the galvanic upshot of physical signals of the interface RS232 between by industrial comptrollers and PC or as transformers of physical levels of logical signals of the interface RS232 in RS485 and vice versa... 2. Transformers is used for organization exchange by digital information between PC and trans- formers-proof-readers "FLOUKOR", "PK-1", "PK-2", "PM-3V" and digital sensors (by transformers measuring) supporting "Opened field HART- protocol". 3. Transformers of interfaces are not the mean of measuring. Page up
