Emerson PM-30 power module for ROC800 and ROC800L RTU flow computers

Emerson Process Management has released an updated power module for the ROC800 and ROC800L RTU flow computers. The PM-30 offers increased power delivery and the flexibility to install the ROC800 in either 12 V solar installations or 24 V rackmounted installations without needing to change the power module.

The PM-30 power module auto regulates any voltage between 11 and 30 VDC. It offers an increased power delivery to the ROC800 I/O of 70 W - exceeding the PM-12’s 60 W and the PM-24’s 30 W. The additional power enables users to expand the I/O in the ROC800 without concern regarding power consumption. The PM-30 module also offers improved monitoring with LEDs indicating the status of the 12 VDC and 3.3 VDC on the backplane.

The ROC800 series flow computers are suitable for a variety of applications for a wide range of liquid hydrocarbons including crude, refined products, special application products, lubricating oils and light hydrocarbons.
