Alarm Relays
The ALERT, DANGER and OK relays are independent,
single-pole-double throw relays. NO, ARM, and NC
contacts are available through a plugable screw
connector at the bottom of the monitor. OK relay
contacts are available on fixed screw terminals at the
bottom front of the alarm module. Relay contacts are
rated 5 Amps at 30 Vdc or 125 Vac, resistive load. This
rating includes any inrush current the load draws. For
loads that are not purely resistive, the contact switching
capability needs to be considered carefully in terms of this
inrush current and rated accordingly.
The user is reminded to take care when applying relays.
The factory intended purpose of providing relay contacts
is to operate relatively low power alarm annunciators, act
as a dry or low dc voltage contact closure input to other
systems, or act to actuate an appropriately sized slave
relay for larger loads such as shutting down a motor.
