Designed specifically for equipment manufacturers who need process monitoring and alarm, the 7HI/ 7HK are easy to configure and use. Factory calibrated, they accept thermocouples, 3-wire Platinum RTD, and mV, mA and Vdc inputs, selectable from the front panel and programmable with filtering and sensor break indication. High or low process alarm setpoints can be programmed and password protected. Alarms can be acknowledged automatically, or manually from the keypad. A bright 4-digit LED display and 6 panel beacons provide process variable, alarm status and other important process information to the operator. Both models are NEMA 4X rated.
Both have a peak high/peak low feature that remembers the highest and lowest detected process variable readings. This sequence can be reset and restarted from the front panel.
7HI - The 7HI has up to 3 independent latchable alarm relays (2 SPDT and 1 SPST) programmed for high or low process alarms. The 7HI is also available with an optional 24 Vac/Vdc supply.

Alarm Standby Function
The
7HI/7HK have an Alarm Standby function to allow masking of the process low
alarm condition if the process variable has not traversed the low alarm
threshold for the first time. |
|
Measurement Offset
A
programmable sensor offset is provided for instances when it is not possible to
locate the sensor in the ideal location. This offset can be applied to all
inputs and is programmable for °C or °F. |
