transmitter signal converter / DIN rail
WST 3 Transmitters are high performance, DIN rail-mounted instruments designed for strain gage based transducer applications. They convert load cell(s) input signals into highly stable analog and digital output signals suitable for PC or PLC based control systems. WST 3 Transmitters typically are used where a local display is essential either for weight/force indication or front panel setup. Setup and calibration procedures are accomplished easily using the front panel or by using PC based deltaCOM software running under Windows 95/98/2000/ NT4/ME/XP. All setup data can be stored in a host computer and quickly downloaded into another WST 3 replacement unit (full deltaCOM software option required). Units are equipped with two relay outputs having a response time of less than 20 msec. for use in high accuracy, level control applications. A unique and patented A/D converter, of high resolution and stability, serves as the heart of the transmitter. This advanced A/D drives both the analog and serial outputs which can be user configured to transmit rapid, accurate, and stable weight/force measurements. WST 3 Transmitters offer on-board fieldbus communication using the Profibus DP format. Fieldbus versions of Profibus DP, DeviceNet, and Modbus Plus also are available through the GATE 3S network module from Nobel. WST 3 Transmitters are compatible with other Nobel instruments and 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 EMC and Low Voltage directives.
