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.
