The module accepts redundant LVDT position feedback and supports AC or DC LVDTs, then regulates redundant protected servo outputs in ±300 mA servo mode or 4-20 mA/20-160 mA I/H modes. It also provides LVDT excitation, scaled and unscaled position outputs, a test output, raise/lower/trip-bias contacts, and a hard-manual output. SPHSS13 works with NTHS03 termination and NKHS03 cable in ABB's documented evolution arrangement and commonly coordinates with SPTPS13 speed detection to form a turbine governor. Compatible HR controllers and exact firmware must be verified for the installed project. ABB lists steam-turbine throttle/control valves, gas-turbine fuel valves, inlet guide vanes, nozzle angle, hydro-turbine servo applications, and non-modulating valve-position reporting among its uses. ABB also documents SPHSS13 as the direct replacement platform for IMHSS03/04/05 and SPHSS03/04/05, but not as their alias or an automatic substitute.
