We have a System:
-2 SEPAM T42 protections-which read 2 active powers, at 20 kV)
-2 MSA 141 convertors- convert active power in 4-20 mA
-TWIDO TWDLMDA20DRT - Telemecanique with TWDAMM3HT, which reads the 2 active powers from MSA 141, makess a sum between them and commands a power generator with 4-20 mA;
Question:
Can I read the active powers directly with PLC from SEPAM T 42 by using digital I/O modules, eliminating the MSA 141 (digital/analog convertor) and analog input/output module?
Thank you very much,
John
