Hardware Specifications

4-20 mA HART Loop Protocol and Channel-to-Channel Isolation

The CON041 converter processes high-frequency electromagnetic impedance variations from the PR6424/006-131 probe into a proportional -4 VDC to -20 VDC output signal. Powered by a negative -23 VDC to -32 VDC supply, the circuit delivers a rapid rise time of less than 15 us to track dynamic vibration phenomena up to 20,000 Hz (-3 dB). Built-in channel-to-channel isolation prevents ground loop current leakage across multi-probe turbomachinery installations. Standard 4-20 mA HART loop protocol compatibility allows digital configuration, parameter polling, and diagnostic tracking when integrated with machinery protection and DCS networks.

Frequently Asked Questions

Q: What power supply voltage is required to operate the CON041 signal converter?

A: The CON041 converter requires a regulated negative DC power supply operating within the range of -23 VDC to -32 VDC.

Q: What is the output signal range of the CON041 converter when connected to the PR6424 probe?

A: The converter generates a proportional negative DC output voltage ranging from -4 VDC to -20 VDC across the static measurement span of +-2.0 mm.

Field Installation Guidelines

• Converter DIN-Rail Mounting: Snap the IP20-rated CON041 converter securely onto a standard 35 mm DIN rail inside an IP54 or higher protective field enclosure to shield it from ambient dirt and moisture.
• Sensor Probe Installation: Thread the PR6424 sensor into the rigid mounting fixture perpendicular to the shaft surface. Set the mechanical air gap using a feeler gauge or voltage meter to establish the zero-displacement reference point before locking the jam nut.
• Cable Shielding and Conduit: Route the sensor armored cable in dedicated grounded conduit separated from AC power lines and VFD conductors. Terminate signal shields at the designated converter grounding bus bar to ensure single-point earthing.
