72-CNV

      The 72-CNV family of converters offer a flexible and reliable solution to the challenge of interfacing devices conforming to different serial communication standards. Grayhill converter products are designed for industrial environments. All communication lines have transient protection which other commercially available converters lack. The converters allow an RS-232 device (ie. PCs, PLCs, Embedded Controllers) to communicate reliably over long distances to multiple devices utilizing the RS-422/485 standard. Reliability is an inherent benefit of the differential mode communication of RS-422/485.
     The 72-CNV has six features.The first one is that it would have selectable RTS operation for 2 wire applications.The second one is that it would have transient protection on the RS-422/485 lines.The third one is that it would have on-board power supply with jumper selectable 110/220 Vac operation.The fourth one is that it would have optical isolation between RS-232 and RS422/485.The fifth one is that it would have DIP switch selectable DTE/DCE setting.The last one is that it would have multiple mounting and connector options.That are all the features.
      Some important electrical specifications and maximum ratings of 72-CNV have been concluded into several points as follow.The first one is about its supply voltage range which would be 110/220 Vac (jumper selectable).The second one is about its maximum supply current (Ips) which would be 120 mA.The third one is about its isolation voltage which would be 4000 Vac.The fourth one is about its transmission rate which would be from 300 to 115200 Baud.The fifth one is about its operating temperature range which would be from 0 to 60°C with 95% relative humidity, non-condensing.The sixth one is about its indicators which inlucded TX, RX, CTS, RTS and power operates only in an RS-422 mode at a maximum rate of 19.2 KB.The next one is about its supply voltage which would be from +8 to +15 Vdc (-2 and -4 versions) and would be +5Vdc (-5 version).The next one is about its supply current which would be 62 mA plus output load (-2 version) and would be 30 mA plus output load (-4 and -5 version).The last one is about its operating temperature range which would be from 0 to 60°C.
