Product Description
ABB HESG448230R1 is an analog input AI module of the HESG / HIEE range for Symphony DCS system. It is a rack-mounted I/O card for ABB Symphony distributed control system, discontinued by OEM and high-value spare part for legacy thermal power and chemical plants. This card receives field signals such as 4-20mA, thermocouple and RTD, provides signal isolation, filtering and A/D conversion, and transmits data to controllers. It supports redundant configuration and connects to Symphony backplane bus, widely used for replacement of measurement loops for boilers and steam turbines.
