产品描述

Application

    ? Fast < 20 ms response time for measuring signals produced by torque, position, current & acceleration sensors.

    ? User configurable bipolar or unipolar I/O means the DRST-DC is suitable for nearly any DC voltage or current       conversion.

    ? Freely programmable between ±300 VDC and ±100 mA. The excitation source allows measurement of a 2-wire or 3-wire transmitter, or a potentiometer.

    ? Converts narrow bipolar inputs to wide bipolar or unipolar outputs, e.g., ± 1 volt input = ± 10 volt or 4 to 20 mA       output.

    ? Configurable input limits control the output value for increased safety.

    ? ±20 VDC buffered voltage output for controlling devices like the PVG 32 valve (6 to 18 VDC).

Technical Characteristics

    ? The latest analog and digital techniques are used to obtain maximum accuracy and immunity to interference.

    ? Possibility of output safety read back by selecting 4 to 20 mA output.

    ? The current output can drive up to 1000 Ω, with an adjustable response time of 0.0…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 a sensor 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   (140oF) ambient temperature.

    ? Configuration, monitoring, 2-point process calibration and more are accomplished using either the DRSL-Display       detachable display or the DRST-CM detachable digital communication enabler.

    ? All programming can be password-protected.
