Many important devices in today's industrial environment still use RS-232 interface. However, RS-232 is a point-to-point interface and the distance is limited to only 15 m between the device and the computer. To overcome these limitations, many users use RS-232 to RS-422/485 converters to connect RS-232 devices to RS-422 or RS-485 networks and transmit data over distances of up to 1.2 km can.
The TCC-100/100I is an isolated RS-232 to RS-422/485 converter for users who require an industrial-grade interface conversion product to increase RS-232 transmission distance and improve networking capability. The superior industrial application design supports DIN rail mounting, terminal block wiring, an external power supply and has optical isolation to protect the system. This makes the TCC-100/100I suitable for use in critical industrial environments. Simply put, RS-232 devices can be used as part of an industrial RS-422/485 network, but without additional hardware or software changes.
