ProTech-GII with Math Functions

Note that with the “Voted Trip Relay” ProTech-GII models, the two solid-state trip relays located on each
module (A, B, C) are not available for use or connection. Each module’s trip signal relays are connected
internally to the ProTech-GII in a 2oo3 voted fashion to drive two redundant Form-C trip relays on the unit’s
2-out-of-3 voted relay module. These two voted redundant relays have normally-open and normally closed
output contacts rated for 220 Vac @ 8 A or 24 Vdc @ 8 A. Refer to Figure 2-14a for relay terminal location
and Figure 2-14d for wiring information.
Figure 2-14d. Example Trip Relay Wiring (Voted Trip Relay Models)
Alarm Relay Output
In both the Independent and Voted Trip Relay versions, each of the three modules (A, B, C) has an alarm
output. The alarm relay output has normally-open type contacts and is rated for 24 Vdc @ 1 A. Refer to
Figure 2-14e or 2-14f for wiring information.
