Refer to the Chapter 3 (Functionality) of this manual for all applicable relay output
specifications and for information on how to configure and use each
programmable relay output in an application.
Relay Outputs (Independent Trip Relay)
Each ProTechTPS “Independent Trip Relay” model has three independent
modules (A, B, C), and each of these modules has five solid-state relay outputs.
Each of the five solid-state relays have normally-open type contacts and are
rated for 24 Vdc @ 1 A. Two of these relay outputs are dedicated as redundant
trip signal outputs, and the other three relay outputs are user-programmable
which can be programmed to function independently as required. The
Independent Trip Relay ProTechTPS models are designed so the each set of trip
relays drive one of three external independent trip solenoids, typically used in 2-
o-o-3 voted trip block assemblies. Refer to Figure 2-16a for relay terminal
location and Figure 2-16b or c for wiring information.
