Models 4WSD9OTB and 4WSD25OTB are our top-of-the-line converters with both isolation and surge protection, removable terminal blocks on the RS-422/485 side make installation easy. Dip switches are used for configuration. LEDs indicate data traffic. Modbus compatible. Power is provided through a 10-48 VDC input on the terminal block.
Model 485OI9TB is a basic isolated converter. The RS-232 side draws power from the RS-232 handshake lines of the connected PC. At least one handshake line must be asserted (high) to power the converter. If high handshake lines aren't available, model 485OT9L is recommended. The RS-422/485 side is powered by an external power supply.
