OFF: Relay normally open
NCHSH: If input signal is higher than the top alarm(contains dead band), the output relay
closes.
NOHSH: If input signal is lower than the top alarm(contains dead band), the output relay
closes.
NCLSL: If input signal falls below the alarm(contains dead band), the output relay closes.
NOLSL: If input signal falls below the alarm(contains dead band), the output relay closes.
NCOUS: If input signal exceeds the top alarm, or falls below the alarm(contains dead
band),the output relay closes.
NOOUS: If input signal exceeds the top alarm, or falls below the alarm(contains dead
band),the output relay closes.
Alarm relay
Relays are normally open and SPST type. after power, After power up, the relay is set to
normally open or normally closed state according to the user about the configuration of the
relay by microcontroller. Relays can be arbitrary, independent setting one of seven kinds of
alarm modes. The alarm states of relay for measurement exceeds the range and for
measurement exceeds the alarm point are the same.
Normally open output: two relay contacts normally open(OFF)when the measered value
in normal.
Normally close output: two relay contacts normally closed(ON) when the measered value
in normal.
