To use the loop power converter module with an HMP60 or HMP110 series probe, the probe must be in the analog output mode. The desired parameter is on channel 1, which must be scaled to 0 ... 2.5 V.
You cannot use the loop power converter with the digital-only HMP110.
When using the loop power converter module, power the module with 8 ... 28 VDC. The operating voltage for the probe (5 VDC) is delivered by the module.
For more information, see the Loop Power Converter Quick Reference Guide (M211106EN).
