Multifunctional DC Signal Converter 4184

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 4184 is suitable for nearly any DC voltage or current conversion.
• Freely programmable between ±300 VDC and ±100 mA.
• The excitation source allows the 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…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…18 VDC).
• Designed according to strict safety requirements and is therefore suitable for application in SIL 2 installations.
• Suitable for use in systems up to Performance Level “d” according to ISO-13849.

Technical characteristics

• The latest analog and digital techniques are used to obtain maximum accuracy and immunity to interference.
• Possibility of output safety readback by selecting S4…20 mA output.
• The current output can drive up to 1000 Ohms, with an adjustable response time of 0.0…60.0 seconds.
• Exceptional mA output load stability of < 0.001% of span / 100 Ohm.
• 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.
• 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 PR’s 4500 series of detachable displays.
• All programming can be password-protected.
