Designed specifically for equipment
manufacturers who require high accuracy process monitoring and alarm, the 7HL
is easy to configure and use. Factory calibrated, the 7HL accepts universal
inputs selectable from the front panel and programmable with filtering and
sensor break indication. Additionally, a 10 segment linearization can be
programmed over the entire span. Display accuracy is 0.1% of span (±1
digit). The 7HL has 2 independent latchable alarm relays, programmed with
password protection for high or low process alarms with a hysteresis of 0.1 to
5% of span. Alarms can be acknowledged |

automatically, or manually from the keypad. A bright 4-digit
LCD numeric display, a 2-digit LCD alphanumeric display and 6 panel beacons
provide process variable, engineering units, alarm status and other important
process and configuration information to the operator. There is also a peak
high/peak low detection feature that remembers the highest and lowest detected
process variable reading. This sequence can be reset and restarted from the
front panel. The 7HL is IP54 rated for dusty environments. |
