Page 43: Figure 2-13A. Example Configurable Input Wiring-Discrete Input (Internal Power Option)
The internal 24 V provides enough power to operate all 10 inputs in discrete mode. For reliability reasons, Woodward recommends that input circuitry for each module (A, B, C) be fully isolated from the input circuitry of the other two modules. For example, the power source and wiring for module A should not be shared or connected in any way to modules B or C.

Optionally all ProTechTPS models can be configured for de-energize- to-trip or energize-to-trip functionality based on the application action required. However, de-energize to trip is a safer way to fail so that a total power loss to the control will trip the prime mover. Woodward...
