Lumel-PD51
Converterter/repeater RS485/RS232 interface

PD51 converter/repeater RS-485/RS-232 interface is a digital device destined to convert the RS-232 into an RS-485 interface or the RS-485 interface into an RS-485 interface without the interference in the format and the structure of transmitted data. Owing to the use of two RS-485 interfaces galvanically separated in the PD51 converter/repeater, for the counteraction to their mutual influences, it can be also used as a repeater of industrial networks what increases the distance of transmitted information.  This converter/repeater can be applied: to connect a PC computer with industrial networks, in applications in which it is necessary to use a PC computer with a visualisation program servicing devices equipped with an RS-485 interface, in side-lines requiring the automatic control of the RS-485 interface transmitter, voltage supply: 7...35V d.c.; 20...40 V a.c/d.c.; 85...253 V a.c./d.c., External dimensions: 22,5 x 120 x 100m
