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.
Models 485DRCI and 485LDRC9 are DIN
Rail mount, wide temp versions of the 4WSD9OTB and 4WSD25OTB
