5.0 DESCRIPTION
The Dynisco model 1392 Linear Input Indicator is a flexible, programmable indicator designed
for analog sensors. The five digit, 0.52” LED display provides a precise, readable indication of
the measured value.
You can program the 1392 to display °C, °F, or None up to a Full Scale Value (F.S.U.) of 99,900
with an accuracy of ± 0.1%. The span value, alarm set points and other constants are stored
indefinitely in non-volatile memory. Easy-to-remember pushbutton sequences simplify
transducer calibration routines.
Two independent SPDT alarm relays are a standard feature of the 1392. The dual high or low
set points are easily programmed from the front keyboard and are displayed on the digital
display. The low alarms can be set as low alarm masked to inhibit alarm action during start up.
Relay contacts are provided to activate an annunciator, or to initiate automatic shutdown if
operating conditions exceed preset limits.
A programmable voltage to current retransmission output is available as an option. You can
select a voltage output of 0 - 5Vdc or 0 - 10Vdc or current outputs of 4 - 20mA or 0 - 20mA to
drive chart recorders or data acquisition equipment.
The Model 1392 can also be supplied with bidirectional and half duplex RS-485 serial
communications. All signals are optically isolated and the baud rate is adjustable between 150
and 19200 baud.
