Emerson PM-30 power module for ROC800 flow computer

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

The product autoregulates any voltage between 11 and 30 VDC. It offers increased power delivery to the ROC800 I/O of 70 W of power, 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 computer without concern regarding power consumption. The module also offers improved monitoring, with LEDs indicating the status of the 12 and 3.3 VDC on the back plane.

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