• The relay can be energized or de-energized
in alarm state (selection via keyboard).
• The outputs can be assigned to alarm
setpoints directly or via logic functions
(AND, OR).
• The outputs can be delayed or assigned
to a hysteresis value (selectable in engineering
units).
• 4 (10) alarm setpoints settable in absolute
value, with functions configurable via
keyboard (direct, reverse, deviation, symmetrical
deviation).
• Setpoint can be set over the entire
selected scale.
• Minimum or maximum setpoint with
latch.
• Setpoint can be excluded in power-up
phase until the input variable has exceeded
the set limit.
A subsequent drop below such limit causes
the relay to trip
