Analog Output
One programmable 4–20 mA analog output per module (A, B, C) is available to
drive a readout meter or interface with other controllers or plant DCS’s
(distributed control systems). This output is designed to drive into an impedance
between 0 to 500 . Twisted shielded pair wiring must be used. Refer to the
Chapter 3 (Functionality) of this manual for applicable analog output
specifications and for information on how to program and use this analog output
in an application.

Relay Outputs
Two basic ProTechTPS model variations are available depending on the required
trip system architecture: the “Independent Trip Relay” model and the “Voted Trip
Relay” model. Either version also has 3 programmable Relay Outputs per
module. Refer to Figure 2-16a for the general locations for Trip Relay Output
wiring in the two models.
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.
