ProTech-GII with “Voted Trip Relay” Output
ProTech-GII “Voted Trip Relay” models consist of three independent modules that each accept one
speed input whose trip output commands are then voted in a 2-out-of-3 (2oo3) fashion to create the 2oo3
trip output command. Two redundant “Form-C” 2oo3 voted relays are used in these models providing four
isolated relay output signals with normally open and normally closed contacts.
