Emerson Process Management has released a new 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-Volt solar installations or 24-Volt rack mounted installations without needing to change the power module. The PM-30 power module auto regulates any voltage between 11- and 30-Vdc. It offers increased power delivery to the ROC800 I/O of 70-Watts of power – exceeding the PM-12’s 60 Watts and the PM-24’s 30 Watts.
The additional power enables users to expand the I/O in the ROC800 without concern regarding power consumption. The new module also offers improved monitoring with LEDs indicating the status of the 12Vdc and 3.3Vdc on the back plane.
The ROC800 series flow computers are designed for a variety of applications for a wide-range of liquid hydrocarbons including crude, refined products, special application products, lubricating oils and light hydrocarbons.
