CCC CM-2-200 Signal Conditioning Module

Product Description

CM-2-200 is a signal conditioning module manufactured by Compressor Controls Corporation, designed for centrifugal compressor anti-surge and turbomachinery control systems. It is a single-channel isolated 4-20mA analog signal conditioning card. It filters, isolates and precisely transmits current signals from field transmitters to suppress common-mode noise, and sends standardized analog signals to CCC main controllers. It supports channel fault diagnostics and features conformal coated PCB. It fits into Vanguard series compressor control cabinets and ensures stable measurement of pressure, differential pressure, temperature and other process signals.
