ABB IMHSS03 Hydraulic Servo Module

Description Harmony rack I/O incorporates a variety of input and output devices to interface process signals to the Symphony™ Enterprise Management and Control System. An IMHSS03 Hydraulic Servo module and an IMFCS01 Frequency Counter module interface field inputs and outputs used in turbine control. The modules each consist of a single printed circuit board that occupies one slot in a module mounting unit (MMU). Configuration: Jumpers and switches on the printed circuit board Jumpers and dipshunts on the termination unit A cable connects the I/O module to its termination unit. The physical connection points for field wiring are on the termination unit. Specifications Property Characteristic/Value General Mounting Occupies one slot in a standard module mounting unit.
