C1-33T

RS232-RS485 dual converter (90-270 Vac, desk version)

C1 Line (serial converters and repeaters)
This line includes a series of high quality industrial devices that are used in setting up networks based on standards RS232, RS422 and RS485; various models are available: with DC (9-36 Vdc) or AC (90-270 Vac) power, for DIN rail mounting or in a desk version; they can be used as universal converters (from RS232 to RS422 or RS485), dual converters (from RS232 to RS485 with two branches) or signal rigenerators (RS422 or RS485). All models can operate with baud rate from 1.2 to 115 kbit/s and automatically sense the direction of the data flow; the triple optical isolation (both line interfaces and power section) and the possibility to set bias and terminating resistances guarantees the safety of data transmission even if affected by strong interference and noise.

The C1-33T is a desk version device suitable for converting a RS232 line into a RS485 line with two branches; it is well suited when the devices to connect to the RS485 line are more than 31 or are located in such a way to make more convenient the presence of two separate branches. Microswitches, with direct access, allow the user to set baud rate (from 1.2 to 115 kbit/s) and bias and terminator resistors (independent for each line). A triple optical isolation galvanically isolates the power section and the two line interfaces.
