Relay Module (RLY)
The RLY is a non-intrinsically safe module that has 8
identical Form C output channels. Each channel has a fuse
and three terminals. Each channel can be configured as
NO or NC with the power off by wiring to the appropriate
terminals. A TS-550 evo console can accommodate up to
24 outputs (8 outputs on up to 3 modules) as space allows.
The diagrams below illustrate two examples of positive
shutdown upon alarm conditions.

amps, use a 10 amp relay module. If the current
rating is higher than 10 Amps, use an appropriate
extension relay.
