DRST-DC DIN Rail Universal Uni/Bipolar DC Signal Conditioner

    • 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.
