2 RELAYS

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.

incl 4-20mA (or 0-10V) retransmit

ADDITIONAL FEATURES INCLUDE:

  • adjustable RESOLUTION by adjusting the position of the decimal point and scale
  • adjustable HYSTERESIS (DIFFERENTIAL)
  • START-UP DELAY: allows the current to stabalize at startup before monitoring starts
  • REACTION DELAY: prevent tripping for a pre-set time period
  • LATCH facility: to force manual reset after fault
  • LATCH can be enabled / disabled for each relay independantly (used when one relay is alarm relay)
  • independantly invert relay action, ie close while in fault condition
  • keypad lock with code
