ABB 216EA61B HESG448230R1/G Analog I/O Board in stock

ABB 216EA61B HESG448230R1/G is a mixed analog input and output I/O board for ABB Symphony / INFI90 DCS system. It collects analog signals from field transmitters and outputs analog control signals to regulators and valves, acting as signal interface between controllers and field process equipment.

This board supports multi-channel configuration with built-in channel isolation and comprehensive diagnostic capability. It is rack-mounted and communicates via Symphony backplane bus, widely used in power plant DCS cabinet maintenance, spare replacement and industrial process control retrofit projects.
