Function:
The TUA-XHL HI-LO Alarm Trip is a microprocessor based instrument. It operates as a combined high trip
and low trip to detect conditions that fall outside a specified operating window. The relay can be configured
as a normally-energized or normally de-energized. A built in two wire supply can be used to connect two wire
sensors to the TUA-XHL.
The output is a SPDT (form "C") contact rated at 10 Amps, 1/8 Hp at 125 VAC. The High and Low setpoints
can be adjusted individually to allow for monitoring virtually any operating window. The delay is adjustable
from 0-1 minute and can be configuerd as ON delay only or as ON and OFF delay. This feature helps prevent nuisance
alarms.
