for I&C/Automation firms in the Carolinas.


I am devoting several new pages to it that will have links to each firm's website: click on links in the TOP menu. I will initially base the information found on the firms web site, then it can be adjusted based on comments from those firms. The listing will carry the firm name & city with a link to the firms web site carried.  Additional information or advertisement can be provided at an additional cost per year. The initial firms will be those that have personal that belong to the ISA


Replacement forMoore Products obsolete

521K, 522K Mini Loading Stations

Production Stations are in process for first order from Duke Energy for replacing the obsolete Moore Products Co 521K (single gauge) and 522K (duplex Gauge) pneumatic Mini Loading Stations.

 HIK-522

 

The 522K (above) was used to operate a pneumatic control valve and the second gauge was assigned to indicate a remote pneumatic signal

 The 512K (single Gauge)  was used to manually operate (open/close) pneumatic control valves.

The designations for the replacement loading stations are

HIK-512 for the MPC 521K

HIK-522 for the MPC 522K

 

The replacement stations were contracted by Duke Energy, designed by Cliff Johnson, PE, Control Systems Engineer and assembled and sold by TRUgegra, a local integration firm in Charlotte NC
