Relay Output Wiring (optional)
As illustrated in the diagram below, the Power Supply Module’s two relay outputs can be used to activate an external
alarm (TS-RA2) and the two inputs can be used to silence that alarm remotely (TS-RK).

Emergency Generator Applications (optional)
The wiring or use of discrete inputs is optional — skip this
section if you don’t plan to use this interface. Discrete
inputs may be wired to a TS-550 evo console with 18
AWG, type TFFN or THWN wire. You may also use THHN
wire in sizes larger than 18 AWG.
Emergency backup power generator run-relay(s) are
wired to the discrete input interface terminals at the TS-
550 evo console. A run-relay closure will stop a leak test
on the associated generator fuel tank. When the generator
run-relay opens (generator stops running), a run report is
produced at the console, which shows the total and hourly
fuel consumption rate during the run cycle.
Note: You must use dry run-relay contacts for this
interface because the TS-550 evo series supplies
+5 VDC digital logic power at the IN (input)
terminals.
Note: It is recommended that you use: IN 1 & GND for
Generator 1 /fuel supply Tank #X, and IN 2 & GND
for Generator 2 /fuel supply Tank #Y. The specific
fuel tank(s) assigned are “programmable.” See
Figure
9 for wiring details.
