DC VOLTAGE INDICATOR / MONITOR / WINDOW COMPARATOR OVER / UNDER VOLTAGE PROTECTION
TThis device is used to display and monitor DC voltage.
Maximum & Minimum values are logged for 24 hours (updated every 60 min).
The latch facility may be de-activated for one or both the relays allowing one relay to be used for control (not latched), and the other as a latched alarm.
Use the “ScAL” parameter for calibration purposes, or to change the number of decimal places displayed (see notes).
Other features include adjust able signal damping, adjustable start-up and reaction delays, the ability to swap the relay’s functionality.
All settings may be locked & code protected to avoid changes from being made by unauthorised personnel.
