Features

High Resolution Displays: The ProTech-SX includes a high-resolution 107 mm (4.2") color display and keypad to allow users to locally monitor configuration settings, statuses, system inputs and outputs, and alarm, trip, and overspeed logs.

Acceleration/Deceleration Detection: Optionally, this safety system can be configured to protect a turbine from high acceleration/deceleration events. The derivative of the speed signal is used to detect turbine acceleration or deceleration and issue an associated trip command.

MPU Detection: The ProTech-SX’s speed-sensor input includes a special MPU open-wire detection circuit to validate that an MPU is properly connected before and during turbine operation. Note: Due to the difference in circuitry, this special, open-wire detection pickup is not available for use with externally mounted pickups.

Sulfur Contamination Resistant: The ProTech-SX utilizes a special conformal coating material that has demonstrated excellent long-term protection against H₂S and SO₂ gases at levels classified in international standard IEC 721-3-3 1994 – environment Class 3C2.
