Description
ABB Bailey NTHS03 6640635A1 Overview
The NTHS03 Hydraulic Servo Termination Unit is a Harmony rack I/O device that is part of the Symphony Enterprise Management and Control System. It provides a signal path between an IMHSS03 Hydraulic Servo Module and a hydraulic servo valve, an I/H converter, or a linear variable differential transformer. The IMHSS03 module is a position control module through which a rack controller can control a hydraulic actuator via a servo valve. By regulating the current to the servo valve, it initiates a change in actuator position. A linear variable differential transformer (LVDT) provides actuator feedback to the IMHSS03 module via the NTHS03 termination unit. Typical uses for this hardware are positioning steam turbine throttle and control valves, gas turbine fuel valves, inlet guide vanes, and nozzle angle.
The NTHS03 termination unit is a seven-by-seven inch square printed circuit board. The board contains:
•Four dipshunt sockets.
•Three terminal strips.
•One fuse holder.
•Two cable sockets.
•24 VDC Faston connector.
•DC common Faston connector.
•One fuse (24 VDC power).
•Four jumpers.
