UNLATCHED Unlatched mode: the relay
goes into its active state
when the control setpoint is
in active (operated) state,
and returns into its non-
active state when the setpoint
is released.
Latched mode: the relay goes
into its active state when the
control setpoint goes into
active state and remains in
the active state until it is
returned into its non-active
state by a remote command.
Pulse mode (normal pulse):
the relay goes into its active
state for the specified time,
goes into non-active state for
the specified time and
remains in the non-active
state.
KYZ mode (transition pulse):
the relay generates transition
pulses. The relay changes its
output state upon each
command and remains in this
state until the next
command.
Polarity
NORMAL (N.O.)
INVERTING
(N.C.)
NORMAL
Normal polarity: the relay is
normally de-energized in its
non-active state and is
energized in its active
(operated) state.
Inverting polarity: the relay is
normally energized in its non-
active state and is de-
energized in its active
(operated) state. It is called
failsafe relay operation.
Pulse width
20-1000 ms
100 ms
The actual pulse width is a
multiple of the 1-cycle time
rounded to the nearest bigger
value.
The pause time between
pulses is equal to the pulse
width.
