Configurable indicators for temperature, pressure, force, current and AC voltage, position, normalized inputs, with up to 4 alarm outputs, analog retransmission output, serial communication
The model 1390 indicator offers a field scalable display and dual, configurable alarms to meet your changing pressure indication requirements. The available optically isolated mA/VDC linear retransmission enables the user to log process trends, a valuable feature for SPC and SQC. A simple front panel instrument calibration and compact profile make the model 1390 the ideal indicator for your process.
The LHL, LHI meets or exceeds factory Mutual (FM) Approval Standard temperature Limit Switches Class 3545.
They are designed to automatically shut down a process when the measured value exceeds a pre-programmed value.
Alarm masking:
Puts the alarms in the stand by condition (mask) during instrument power up or masks a deviation or band alarm if the alarm condition is a
result of a set point change. In both situations the instrument maintains the alarm masking for the duration of the alarm condition.
Logic input:
These instruments are equipped with a logic input used to acknowledge an alarm condition by an external contact.
Maximum and/or minimum data hold:
The LHI is able to memorize the maximum and the minimum measured value. This function is automatically enabled at instrument power up
and it is always active.
Power supply failure indication:
These instruments are able to signal if a power failure occurs during normal instrument operation.
Power fail recovery settings are user configurable.
