Transmitter - AST 3IS - 5844 Transmitter AST 3IS

Transmitter AST 3IS

• Unique design to allow transducers in hazardous areas without the need of zener barriers• Analogue output ± 10 VDC, ±0–20 or 4–20 mA• Serial communications: RS-485, MODBUS RTU protocol• Relay outputs • Compact DIN rail mounting • CE compliant – EMC and Low Voltage the deltaCOM program 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 AST 3IS is compatible with other instru-ments in the Vishay Nobel program and can com- municate via the RS-485/MODBUS RTU protocol with a common process control host – PC/PLC. Fieldbus communication is possible via the GATE 3 module from Vishay Nobel.The transmitter is CE marked, and fully compliant with the EMC and Low Voltage directives. • ATEX II (1) GD approved• Excellent performance in spite of Ex version• Fully isolated • Simple earthing (compared with zener barriers)• Direct connection of transducers in hazardous areas without the need of zener barriers The unit AST 3IS is a DIN rail mounted, high performance isolation amplifi er designed for applications with strain gauge transducers inside hazardous areas.AST 3IS has at its heart a unique Nobel patented analogue to digital converter. The unit is equipped with analogue as well as digital outputs which can be conditioned to give the user accurate, stable and fast response measurement information.The transmitter is fi tted with two relay outputs having a short response time for use in high precision level control applications.The set-up and calibration procedure is easily performed either from the front panel or by using
