Descrizione

Application
• The 0 to 5 AAC RMS range makes it possible to accurately measure a typical current transformer.
• The 0 to 300 Vac RMS range allows accurate supply voltage monitoring.
• DRST-AC measures standard input ranges, and can be freely configured to customer-defined input range.
• Converts narrow AC current/voltage inputs to wide bipolar or unipolar outputs, e.g. 0 to 1 VAMS input = ±10 volt or 4 to 20 mA output with a minimum span of 0.5 AAC RMS or 0.5 Vac RMS.
• Configurable input limits control the output value for increased safety.
Technical Characteristic
• The latest analog and digital techniques are used to obtain maximum accuracy and immunity to interference.
• Possibility of output safety feedback by selecting S4 to 20 mA output.
• The current output can drive up to 800 Ω, with an adjustable response time of 0.0 to 60.0 seconds.
• Exceptional mA output load stability of <0.001% of span/100 Ω
. • Meets the NAMUR NE21 recommendations, ensuring high accuracy in harsh EMC environments.
• Meets the NAMUR NE43 recommendations, allowing the control system to easily detect an input error.
• Each unit is tested to a high 2.3 kVac, 3-port galvanic isolation level.
• Excellent signal to noise ratio of > 60 dB.
Mounting/Installation/Programming
• Very low power consumption means units can be mounted side by side without an air gap – even at 60°C ambient temperature.
• Configuration, monitoring, 2-point process calibration and more are accomplished using either the 4501 detachable display or the 4511 detachable digital communication enabler.
• All programming can be password-protected.
