Toshiba TCNV485-232C Signal Converter
Toshiba Updated: 2007-07-18The TCNV485-232C is a RS485 to RS232 converter. It is primarily used to go from a computers RS232 port to the RS485 port on a PLC. It can also be used to go from the RS232 port on a PLC to the RS485 port on a higher level controller. The TCNV485-CMOS is a RS485 to CMOS/TTL converter. It is primarily used with ASDs (Adjustable Speed Drives) that do not have an RS485 port but need to be networked to a higher level controller.
Key Features
- Power and Transmit LEDs for each port to show operation status.
- Designed for rugged industrial environments.
- Screw or DIN rail mountable.
- TCNV485-CMOS has 40 cm cable with RJ45 connector for connection to ASD.
