Transmitter - WST 3 - 5844 Transmitter WST 3

Transmitter WST 3

• Analogue output ± 10 VDC, 0–20 or 4–20 mA• Serial communications: RS-485, MODBUS RTU protocol The transmitter has at its heart a unique Vishay Nobel patented completely digital A/D converter. This advanced technology provides both analogue and serial outputs which can be conditioned to give the user accurate, stable and rapid response measure- ment information.The WST 3 is ready for fi eldbus communication in Profi bus DP. Fieldbus communication is also possible via the GATE 3S module from Vishay Nobel.The WST 3 is compatible with other instruments in the Vishay Nobel programme and can communicate via standard RS-485/MODBUS RTU protocol with a common process control host – PC/PLC.The transmitter is CE marked, and fully compliant with the EMC and Low Voltage directives. • Fieldbus interface: Profi bus DP • The unit WST 3 is a DIN rail mounted, high perfor-mance transmitter designed for applications with strain gauge transducers. It converts the output from connected load cells into a very stable signal suitable for PC or PLC based control systems.WST 3 is typically used where a local display is essential either for displaying data or for front panel set-up. The set-up and calibration procedure is easily performed either from the front panel or by using the deltaCOM programme via a standard PC running under Windows 95/98/2000/NT4/ME/XP. All set-up data can be stored in the host computer and down- loaded in case of replacement of the transmitter. This requires deltaCOM full version (option).The transmitter is fi tted with two relay outputs having a response time of less than 20 msec. for use in high precision level control applications. Tare, Gross/Net and Zero function(power failure safe)• Internal resolution >8 000 000 counts • Relay outputs (level mode/setpoint mode) • Compact DIN rail mounting • CE compliant – EMC and Low Voltage
