Many important devices used in today's industrial environment are still designed for use with an RS-232 interface. However, RS-232 is a point-to-point interface, and it imposes a distance limitation of only 15 meters between the device and the computer. To overcome these limitations, many users employ RS-232 to RS-422/485 converters, allowing RS-232 devices to connect to an industrial RS-422 or RS-485 network and transmit data over distances up to 1.2 km.TCC-100 is an isolated RS-232 to RS-422/485 converter designed for users who need an industrial grade interface conversion product to extend RS-232 transmission distance and increase networking capability. Its superior industrial application design, which includes DIN-Rail mounting, terminal block wiring, external terminal block power, and optical isolation for system protection, makes TCC-100 suitable for use in critical industrial environments. Simply put, your RS-232 devices can be used as part of an industrial RS-422/485 network, but without any hardware or software changes.
