VJET<br />

Ethernet/RS-485 Converter<br />

VJET<br />

The VJET Ethernet/RS-485 converter is a compact, plug-in<br />

type communication converter that uses the Modbus/TCP<br />

pro to col for connecting to host devices with Ethernet<br />

capability, and uses the Modbus/RTU protocol for<br />

connecting to devices with RS-485 communication<br />

function.<br />

Support for a Variety of Applications<br />

Features<br />

• Enables monitoring of multiple widely separated sensor<br />

sig nals from a single location via Ethernet. Up to 31<br />

sourc es can be monitored per VJET unit.<br />

• Monitoring systems can be set up quickly using<br />

DAQWORX* software (recommended).<br />

*DAQWORX Data Acquisition Software Suite<br />

• Installs in your existing LAN with a minimum of<br />

additional wiring.<br />

• 29.5 mm wide (installed) space-saving design. Mounts<br />

eas i ly on the wall or on DIN rails. Can be rack-mounted<br />

when installed in the VJCE-01A mounting base for<br />

communication.<br />

• Choose 24 VDC or 100-240 VAC/DC power supply<br />

spec i fi ca tions.<br />

• Supports CSA, CE, and UL safety standards.<br />
