ABB NHSS01 is a Hydraulic Servo Module for the Bailey Infi 90 product family.
From a maintenance perspective, this class of component belongs to the position loop, where feedback and control functions are coordinated for compatible servo, actuator, or turbine equipment. The installed revision should be confirmed before the product is applied.
In an Infi 90 installation, modules are assigned distinct control, signal, communication, and support responsibilities. Preserving the exact product identity helps maintain the configuration documented for the affected control node. The plant's maintenance records should support final product selection.
In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Exact operating details should be taken from the installed model documentation.
